This book was released on 2011 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron oxides magnetic nanoparticles (MPs) of high crystallinity, high magnetization, and size-monodispersity were synthesized with oleic acid as their native ligands. These hydrophobic and non-functionalized MPs have magnetic properties that are suitable for various biological applications. Surface modifications were studied for transferring these MPs into biological environments as well as transforming them into functional nanoparticles. Certain surface modifications of MPs, such as attaching silane groups and silica coating, lead to formation of more complex structures of superparamagnetic and fluorescent silica microspheres and nanostructures. These microspheres and nanostructures comprising MPs and semiconductor quantum dots (QDs) are useful tools for biological applications such as for magnetically controlling with fluorescent tracking of particles and for bimodal imaging. Surface modifications of MPs with hydrophobically-modified polyacrylic acid (mPAA) amphiphilic polymer and catechol-derivative surfactants resulted in hydrophilic MPs that are stable in physiological environment and small in their hydrodynamic size. These MPs are also designed to possess active functional groups that are necessary for further conjugations with proteins and molecules of interest. These hydrophilic and functional MPs are useful in biological applications such as magnetic resonance imaging and sensing applications.

This book was released on 1999-09-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timely information on scientific and engineering developments occurring in laboratories around the world provides critical input to maintaining the economic and technological strength of the United States. Moreover, sharing this information quickly with other countries can greatly enhance the productivity of scientists and engineers. These are some of the reasons why the National Science Foundation (NSF) has been involved in funding science and technology assessments comparing the United States and foreign countries since the early 1980s. A substantial number of these studies have been conducted by the World Technology Evaluation Center (WTEC) managed by Loyola College through a cooperative agreement with NSF. The National Science and Technology Council (NSTC), Committee on Technology's Interagency Working Group on NanoScience, Engineering and Technology (CT/IWGN) worked with WTEC to develop the scope of this Nanostucture Science and Technology report in an effort to develop a baseline of understanding for how to strategically make Federal nanoscale R&D investments in the coming years. The purpose of the NSTC/WTEC activity is to assess R&D efforts in other countries in specific areas of technology, to compare these efforts and their results to U. S. research in the same areas, and to identify opportunities for international collaboration in precompetitive research. Many U. S. organizations support substantial data gathering and analysis efforts focusing on nations such as Japan. But often the results of these studies are not widely available. At the same time, government and privately sponsored studies that are in the public domain tend to be "input" studies.

Download or read book Synthesis Surface Functionalization and Biological Testing of Iron Oxide Nanoparticles for Development as a Cancer Therapeutic written by Stanley Eugene Gilliland (III) and published by . This book was released on 2015 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron oxide nanoparticles are highly researched for their use in biomedical applications such as drug delivery, diagnosis, and therapy. The inherent biodegradable and biocompatible nanoparticle properties make them highly advantageous in nanomedicine. The magnetic properties of iron oxide nanoparticles make them promising candidates for magnetic fluid hyperthermia applications. Designing an efficient iron oxide nanoparticle for hyperthermia requires synthetic, surface functionalization, stability, and biological investigations. This research focused on the following three areas: optimizing synthesis conditions for maximum radiofrequency induced magnetic hyperthermia, designing a simple and modifiable surface functionalization method for specific or broad biological stability, and in vitro and in vivo testing of surface functionalized iron oxide nanoparticles in delivering effective hyperthermia or radiotherapy. The benzyl alcohol modified seed growth method of synthesizing iron oxide nanoparticles using iron acetylacetonate as an iron precursor was investigated to identify significant nanoparticle properties that effect radiofrequency induced magnetic hyperthermia. Investigation of this synthesis under atmospheric conditions revealed a combination of thermal decomposition and oxidation-reduction mechanisms that can produce nanoparticles with larger crystallite sizes and decreased size distributions. Nanoparticles were easily surface functionalized with (3-Glycidyloxypropyl)trimethoxysilane (GLYMO) without the need for organic-aqueous phase transfer methods. The epoxy ring on GLYMO facilitated post-modifications via a base catalyzed epoxy ring opening to obtain nanoparticles with different terminal groups. Glycine, serine, [gamma]-aminobutryic acid (ABA), (S)-( - )-4-amino-2-hydroxybutyric acid (SAHBA), ethylenediamine, and tetraethylenepentamine were successful in modifying GLYMO coated-iron oxide nanoparticles to provide colloidal and varying biological stability while also allowing for further conjugation of chemotherapeutics or radiotherapeutics. The colloidal stability of cationic and anionic nanoparticles in several biologically relevant media was studied to address claims of increased cellular uptake for cationic nanoparticles. The surface functionalized iron oxide nanoparticles were investigated to determine effects on cellular uptake and viability. In vitro tests were used to confirm the ability of iron oxide nanoparticles to provide effective hyperthermia treatment. S-2-(4-Aminobenzyl)-1,4,7,10-tetraazacyclododecane tetraacetic acid (DOTA) was coupled to SAHBA and carboxymethylated polyvinyl alcohol surface functionalized iron oxide nanoparticles and radiolabeled with 177Lu. The capability of radiolabeled iron oxide nanoparticles for delivering radiation therapy to a U87MG murine orthotopic xenograft model of glioblastoma was initially investigated.

Download or read book Iron Oxide Nanoparticle Surface Modification written by Richard Hoff and published by . This book was released on 2019 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multifunctional nanomaterials can be engineered to aid in the diagnosis of diseases, enable efficient drug delivery, monitor treatment progress over time, and evaluate treatment outcomes. This strategy, known as theranostics, focuses on the combination of diagnostic and therapeutic techniques to provide new clinically safe and efficient personalized treatments. The evaluation of different nanomaterials' properties and their customization for specific medical applications has therefore been a significant area of interest within the scientific community. Iron oxide nanoparticles, specifically those based on iron (II, III) oxide (magnetite, Fe3O4), have been prominently investigated for biomedical, theranostic applications due to their documented superparamagnetism, high biocompatibility, and other unique physicochemical properties. The aim of this thesis is to establish a viable set of methods for preparing magnetite (iron oxide) nanoparticles through hydrothermal synthesis and modifying their surfaces with organic functional groups in order to both modulate surface chemistry and facilitate the attachment of molecules such as peptides via covalent bond formations. Modifying their surfaces with biomolecules such as peptides can further increase their uptake into cells, which is a necessary step in the mechanisms of their desired biomedical applications. The methods of nanoparticle synthesis, surface functionalization, and characterization involving electron microscopy (e.g., SEM, TEM), zeta potential measurements, size analysis (i.e., DLS), and FT-IR spectroscopy will be presented.

Download or read book Green Nanoparticles written by Jayanta Kumar Patra and published by Springer Nature. This book was released on 2020-04-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is the application of science to control matter at the molecular level. It has become one of the most promising applied technologies in all areas of science. Nanoparticles have multi-functional properties and have created very interesting applications in various fields such as medicine, nutrition, bioenergy, agriculture and the environment. But the biogenic syntheses of monodispersed nanoparticles with specific sizes and shapes have been a challenge in biomaterial science. Nanoparticles are of great interest due to their extremely small size and large surface-to-volume ratio, which lead to both chemical and physical differences in their properties (e.g., mechanical properties, biological and sterical properties, catalytic activity, thermal and electrical conductivity, optical absorption and melting point) compared to bulk of the same chemical composition. Recently, however, synthesizing metal nanoparticles using green technology via microorganisms, plants, viruses, and so on, has been extensively studied and has become recognized as a green and efficient way for further exploiting biological systems as convenient nanofactories. Thus the biological synthesis of nanoparticles is increasingly regarded as a rapid, ecofriendly, and easily scaled-up technology. Today researchers are developing new techniques and materials using nanotechnology that may be suitable for plants to boost their native functions. Recently, biological nanoparticles were found to be more pharmacologically active than physico-chemically synthesized nanoparticles. Various applications of biosynthesized nanoparticles have been discovered, especially in the field of biomedical research, such as applications to specific delivery of drugs, use for tumor detection, angiogenesis, genetic disease and genetic disorder diagnosis, photoimaging, and photothermal therapy. Further, iron oxide nanoparticles have been applied to cancer therapy, hyperthermia, drug delivery, tissue repair, cell labeling, targeting and immunoassays, detoxification of biological fluids, magnetic resonance imaging, and magnetically responsive drug delivery therapy. Nanoparticle synthesis for plant byproducts for biomedical applications has vast potential. This book offers researchers in plant science and biomedicine the latest research and opportunity to develop new tools for the synthesis of environmentally friendly and cost-effective nanoparticles for applications in biomedicine as well as other various fields.
Download or read book Multifunctional Iron Oxide Nanoparticles for Biomedical Applications written by Yaolin Xu and published by . This book was released on 2014 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the preparation of multifunctional nanoparticles through the integration of iron oxide nanoparticles with other desired moieties. Iron oxide nanoparticles have been widely explored in localized therapy, targeted delivery, and magnetic resonance imaging. However, inaccessible MRI instruments for most research labs and lack of targeting ligands limits the further exploration of iron oxide nanoparticles in routine tumor diagnosis and efficient therapy. Therefore, the preparation of dual-imaging or targeted nanoparticles is highly desirable. In our studies, fluorescent gold nanoclusters or anti & ndashdisialoganglioside & ndashGD2 monoclonal antibodies are integrated onto iron oxide nanoparticle surfaces. The gold nanoclusters provide additional fluorescent imaging capability, which can be easily accessed in common research labs. The conjugation of cancer cell & ndashtargeting antibodies allows for specific localization of nanoparticles. Indeed, these are the two central themes of this dissertation. To prepare multifunctional nanoparticles, high & ndashquality iron oxide nanoparticles were first synthesized in organic solvents following a modified & ldquoheat & ndashup & rdquo method. During synthesis, a modification was made by introducing a co & ndashsurfactant (trioctylphosphine oxide & ndashTOPO). TOPO facilitated the subsequent ligand exchange process because it weakly bound to nanoparticle surfaces and prevented the formation of densely & ndashpacked surfactant coatings. As a result, hydrophilic molecules (such as polyacrylic acid, polyethylenimine, glutathione and dopamine) were capable of replacing the original ligands, yielding water & ndashsoluble iron oxide nanoparticles. In addition to water solubility, dopamine coatings offered nanoparticles additional conjugation capability upon surface oxidization. These surface & ndashoxidized nanoparticles can directly conjugate with amine and/or thiol group & ndashcontained molecules through Michael addition and/or Schiff base formation. Using this conjugation strategy, dual & ndashimaging nanoparticles were prepared by integrating dopamine & ndashcoated nanoparticles with protein (such as bovine serum albumin, trypsin and lysozyme) & ndash encapsulated fluorescent gold nanoclusters. All integrated nanoparticles maintained their functionalities and structural integrity in biological environments. Furthermore, effects of protein characteristics on the photo & ndashchemical properties of gold nanoclusters and integrated nanoparticles were systematically examined. Similarly, cancer cell & ndashtargeting molecules (e.g. anti & ndashGD2 monoclonal antibodies) were conjugated onto dopamine & ndashcoated nanoparticles. After conjugation, antibodies retained their high targeting specificity, suggested by our cellular targeting studies. More promisingly, conjugated nanoparticles were capable of transporting into cytosols, which opens up new possibilities in cancer & ndashcuring drug loading and targeted therapy. Besides these already & ndashpublished works, we have studied the biological responses of human monocytes to different surface & ndashcharged iron oxide nanoparticles (manuscript in preparation). For dual & ndashimaging nanoparticles, their stability and bio & ndashimaging potential will be evaluated in phorbol myristate acetate (PMA) & ndashtreated monocytes using differential interference contrast (DIC) and confocal microscopy.
