Book excerpt: This thesis involves synthesis, derivatization and biomedical applications of mesoporous silica nanopartilces (MSNs) and Fe3O4@SiO2 core/shell nanoparticles. Chapter 1 introduces the development of MSNs including the mesopores formation mechanism, synthesis conditions and their capability to act as stimuli responsive drug delivery platforms. In chapter 2, the synthesis optimization of different kinds of particles and their surface derivatization are introduced. Chapter 3 & 4 give specific examples of successful optimization and in vitro and in vivo application of MSNs enabled with pH-sensitive nanovalves and disulfide snap-tops for delivering the antibiotic moxifloxacin. It is shown that a high release capacity is necessary to reach a high efficacy ratio, compared with free drug. Chapter 5 discusses the uptake and release capacities of Fe3O4@SiO2 core/shell nanoparticles when modified with a pH-sensitive nanovalves, and its thermally cargo release behavior when surrounding temperature increases or an oscillating magnetic field is applied. In Chapter 6, successful distribution of Fe3O4@SiO2 core/shell nanoparticles in biofilms and on-command release of cargo inside biofilms are shown. Overall, these chapters demonstrate the ability of modifying both the outer surface and interior of MSNs, and their capability to act as a biocompatible controlled release platform that is more effective than equivalent amount of free drug.

This book was released on 2019 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multifunctional mesoporous silica nanoparticles (MSNs) have aroused much attention during the past decades for drug delivery and bioimaging applications because of their intrinsic properties including extremely high surface area, large pore volume, tunable pore diameter, easy surface modification, and high biocompatibility. Even though MSNs have these preeminent properties, rendering this unique nanostructure a promising nanocarrier for biomedical applications, several hurdles still challenge the fields of drug delivery and bioimaging when using MSNs as the nanocarries: (i) high loading and high release amounts of water-insoluble drugs delivered to the site of diseases; (ii) precise control of the dosage of drugs delivered to the site of diseases using non-invasive external stimuli; and (iii) construction of MSNs-based shortwave infrared optical imaging contrast agents as an innovative tool for bioimaging and cancer diagnostics. Therefore, this dissertation primarily focuses on the development of innovative strategies that solve these unmet needs and that advance the research in the field of biomedical applications using MSNs as the nanocarriers. In this dissertation, first of all, we review the research work, which mainly focuses on the design and synthesis of multifunctional MSNs and nanomachines for biomedical applications in Accounts of Chemical Research. A wide variety of nanomachines responsive to the different stimuli (pH, redox, enzyme, heat, light, and/or magnetic field) are discussed in this Account. Additionally, we develop a facile strategy for MSNs delivery and release of the water-insoluble drug clofazimine (CFZ), which is used to treat multidrug-resistant tuberculosis. The strategy employs a companion molecule as a chaperone to improve both the loading of CFZ into the pores of MSNs and its subsequent release, thus enabling both high loading and high release of this water-insoluble drug by MSNs. In vitro treatment of macrophages infected with Mycobacterium tuberculosis with the optimized CFZ-loaded MSNs killed the bacteria in the cells in a dose-dependent manner. These studies demonstrate a highly efficient method for loading nanoparticles with water-insoluble drug molecules and the efficacy of the nanoparticles in delivering drugs into eukaryotic cells in aqueous media. Additionally, we used a noninvasive alternating magnetic field (AMF) to stimulate and control the dosage of drug release from MSNs. Noninvasive stimuli-responsive drug delivery using AMF in conjunction with superparamagnetic nanoparticles also offers the potential for the spatial and temporal control of drug release. In vitro studies showed that the death of pancreatic cancer cells treated by drug-loaded nanoparticles was controlled by different lengths of AMF exposure time due to different amounts of drug released from the carriers. Finally, to develop a new shortwave infrared (SWIR) optical imaging contrast agent which has a higher tissue penetration depth, we demonstrate that J-aggregates of near infrared (NIR) fluorophore IR-140 can be prepared inside hollow mesoporous silica nanoparticles (HMSNs) to result in nanomaterials that absorb and emit SWIR light. The use of J-aggregates stabilized in HMSNs as SWIR imaging agents has the potential to overcome the stability, toxicity, and brightness challenges of contrast agents for this compelling region of the electromagnetic spectrum. Collectively, in this dissertation, we explore and develop innovative strategies to load and deliver high amounts of water-insoluble drugs; control the dosage of anticancer drugs released from MSNs triggered by an AMF; and establish a new SWIR optical imaging contrast agent based on the superior carriers - MSNs.

Book excerpt: The publication of this book was undertaken with two purposes in view: to bring together informatian on the deposition by living organ isms of unique skeletal structures composed of amorphous silica, and to review recent data on the involvement of silicon in physiological and biochemical processes. Although widely varying viewpoints are represented, all the contributors are very interested in the events in volved in the formatian of siliceaus structures and their function. Data presented deal with these questions in a variety of plant and animal systems, and at levels ranging from the evolutionary to the biochemical and ultrastructural. Innovations in electron microscopy and, indeed, the advent of electron microscopy itself, have stimulated many ultra structural studies of silica deposition, work which has deepened and widened the interest in those organisms which routinely produce "glassy skeletons. " The question of how silicon participates in biological systems in volves a spectrum of fields that indudes the chemistry of silicon per se, its biogeochemistry, biochemistry, ecology, and so forth. In this book, however, attention is focused up on the biological aspects of silicon and siliceous structures, with emphasis on the evolutian, phylogeny, morphology, and distribution of siliceaus structures, on the cellular as peets of silica deposition, and on the physiological and biochemical roles of silicon. This volume represents the first compilatian of such data. Because such a variety of subjects and fields are covered, the reader will have to glean for himself some of the comparative aspects of the data.

Download or read book Stimuli responsive Breakable Hybrid Organic inorganic Silica Nanoparticles for Biomedical Applications written by Ricardo Totovao and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To overcome the limitations of most of the drugs avaible nowadays on the market due to their lack of solubility and specifity in cancer treatment for instance, nanomedicine plays an emerging role as an alternative. In that field, nanoparticles are endowed with several advantages, leading them to be highly considered for drug delivery systems preparation. In this respect, silica nanoparticles have recently a great deal of attention from the scientists. Nevertheless, some issues related to the in vivo elimination of silica materials represent the main obstacle impeding their clinical translation. To elucidate this problematic, we report, in this thesis, the use of breakable hybrid organosilica nanoparticles where one is mesoporous and the other one consists in a nanocapsule without porosity. Such materials have been prepared by incorporating an imine-based linker in the particles framework in order to make them pH-responsive. The advantage of the pH sensitivity relies on the fact that cancerous media present certain acidity as compared to those healthy. The particles exhibit a high pH sensitivity where, at low pH, they fully break down, while a good stability is observed in physiological conditions. Furthermore, in vitro studies performed with a drug delivery system based on the mesoporous particle and a highly hydrophobic drug show a remarkable efficiency towards a cancer cell line from human breast, which moreover, rapidly internalises the material. The nanocapsule loaded with a hydrophilic drug also demonstrates a fast internalisation towards a commonly used cancer line which does not resist to the system and thus dies by a very high rate.
