This book was released on 2008 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the synthesis and characterization of functionalized biosurfaces that can be used for bioseparations and bio-nanotechnology are reported. A novel protein purification technique that incorporates chelating ligands and polymers onto the same chromatographic matrix is explored. A polysaccharide based gel, agarose, was modified systematically with hybrid ligands of the chelator iminodiacetic acid (IDA) and the polymer polyethylene glycol (PEG). The PEG molecule acts as a blocking polymer that can allow only small proteins to permeate onto the matrix surfaces and form conventional immobilized metal ion affinity chromatographic (IMAC) interactions with the chelators. Kinetic studies of chelator and polymer attachment were performed in order to effectively control the chelator and polymer densities on the matrix. Studies with different PEG surface densities and their effects on the adsorption of several proteins (e.g. myoglobin, lysozyme and bovine serum albumin (BSA)) were evaluated to characterize these new hybrid size exclusion IMAC (SEIMAC) matrices. An exclusion effect was observed while adsorption as observed in IMAC systems took place. Functionalization schemes and procedures were extended in the activation and incorporation of affinity ligands on inorganic surfaces such as gold surfaces. Functional gold platforms were explored for development of nano-interconnects via functionalized self assembled monolayers (FSAMs) on gold to attach specific affinity ligands as linkers to immobilize biomolecules, such as microtubules (MTs). MTs eventually could be utilized as self assembling structures and templates for fabrication of nano-scale bio-interconnect arrays and networks. In this work, different organothiols were used to form FSAMs and anti-glutathione S-transferase was attached as a linker to utilize the attachment of MT cap proteins, gamma-tubulin. The gamma-tubulin could recognize specifically a heterodimer of the MTs and can provide a nucleation center for MT growth. Several methodologies were employed including photolithographic methods and the use of photoreactive compounds for proper micro/nano scale dual protein functionalization of surfaces with homogeneous affinity ligands and with heterogeneous ligands as well.

This book was released on 2014 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present thesis Supramolecular chemistry is exploited to approach applications in the area of Nanomedicine, and it is, focused on the design and preparation of different micro and nanotools for sensing and therapy, in living cells. Initially, the combination of silicon surface chemistry with the incorporation of bioactive molecules has been investigated in order to obtain a potentially microtool suitable for cell tagging. Furthermore, the design and synthesis of organic compounds as intracellular chemosensors was also explored. On the other hand, this report also includes the synthesis and characterization of dissymmetrical porphyrin derivatives and their subsequent incorporation to metal nanoparticles (gold and iron oxide) for their use in photodynamic therapy (PDT), due to their capacity to produce reactive oxygen species after irradiation, inducing the cell death. The preparation of novel metallo-porphyrins as components of molecular machines was also achieved. First, the formation of self-assembled monolayers (SAM) on polysilicon surfaces was investigated, using different silanes to obtain a functionalization protocol which can be easily repetitive and effective. Thus, three silanes with different functional groups, an aldehyde, an epoxide and an activated ester, have been tested to prepare a SAM and subsequently, prompting us to immobilize a bioactive molecule. Different parameters of the functionalization methodology have been examined, such as the silanization time, deposition method, the type of solvent and silane concentration. Once the SAM formation was optimized, the immobilization of the protein what germ agglutinin (WGA) was achieved, because its ability of cell membrane recognition. The WGA used, included a fluorescent dye (Texas red) to be able to characterize the immobilization of the protein on a silicon surface by fluorescence microscopy, and similar successful results were obtained in the three different silanes used. The same methodology (SAM formation and WGA immobilization) was subsequent applied in silicon encoded microparticles designed for tagging cells. Experiments using mouse embryos have been performed to determine the extracellular adhesion level of the encoded microparticles, resulting above 90 % in all cases. Proper immobilization of WGA protein was the key factor in cell labeling, because WGA recognizes specifically certain carbohydrates expressed in the external membrane (zona pellucida) of the embryo. Synthesis and immobilization of an aminoanthracene derivative as pH sensor was carried out, and its subsequent immobilization on silicon microparticles was achieved. Fluorescence spectroscopy measurements demonstrated that the aminoanthracene derivative immobilized on silicon microparticles could be a potential microtool for sense intracellular pH. Fluorescence spectroscopy experiments showed an important increase at acid pH, whereas from pH 7 to pH 12 the fluorescence emission was very low. On the other hand, aminoanthracene incorporating an aza-crown ether was also prepared as a possible candidate for calcium sensing. Preliminary studies using fluorescence spectroscopy, demonstrated a good selectivity for calcium in comparison with other cations such as magnesium, sodium and potassium. Dissymmetrical porphyrin derivatives have been synthesized and then immobilized on gold and iron oxide nanoparticles, obtaining water soluble metallic nanoparticles incorporating the photosensitizer. The capacity to produce singlet oxygen to induce the cell death following irradiation was investigated, resulting porphyrin immobilized gold or iron oxide nanoparticles. Thus, the prepared porphyrin derivatives and their corresponding nanotools exhibited a high formation of singlet oxygen, resulting nanotools potentially suitable for PDT. Otherwise, anti-erbB2 antibody, a specific antibody for a membrane receptor overexpressed in breast cancer cells, was immobilized onto water soluble porphyrin-gold nanoparticles. Preliminary experiments in a breast cancer cell line, demonstrated the capacity of the porphyrin-antibody-gold nanoparticle to produce the cell death following irradiation. Finally a metallo-porphyrins derivative was synthesized and characterize as a promising component for molecular rotors.

Download or read book Using Biomolecular Recognition to Selectively Self assemble Microsale Components Onto Patterned Substrates written by Trevor Olsen and published by . This book was released on 2015 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern nanofabrication technology in the 21st century has continued year after year to push the boundaries of what is possible at the nanoscale. With the advent of molecular electronics, single electron devices, nanoelectromechanical systems (NEMS), and other nanotechnologies, the near future will see a requirement for the die-to-substrate assembly of components that are much smaller than conventional robotic pick-and-place technologies can accommodate. Many researchers have proposed the mechanism of self-assembly to replace robotic pick-and-place technologies and meet the micro/nanoscale assembly needs of some future technologies. Presented here is a biologically inspired approach for the selective self-assembly of micron-scale components onto lithographically patterned target sites on a substrate. Two mechanisms of selective adhesion through biomolecular recognition are explored and tested in this thesis: the strong protein-ligand interaction between avidin and biotin, and the hybridization interaction that occurs between two complementary single-stranded DNA oligonucleotides. Other than the benefits in scale, the method of integration by self-assembly may be advantageous for its parallel nature, 3D capabilities, and the ability to integrate devices made from incompatible processing technologies into a single platform (heterogeneous integration). Square silicon microtiles with widths ranging from 5 μm to 25 μm were chosen to be test devices (model 'nanochips') for the assembly. These devices, fabricated from silicon-on-insulator (SOI) substrates, were coated with a thin film of gold on one side, deposited by sputtering. A buffered oxide underetch of the buried SiO2 layer left the microtiles attached to the SOI handle substrate only by narrow SiO2 pillars. This allowed for facile release of the microtiles into solution from the front side of the substrate by ultrasound fracture of the SiO2 pillars in a bath sonicator. In the initial demonstration, self-assembled monolayers (SAMs) were employed to functionalize both the microtiles and the gold pads with biotin and avidin, respectively. Preliminary experiments employed commercially functionalized gold nanoparticles and polystyrene microspheres to develop reliable procedures for forming avidin and biotin SAMs on gold. After the gold-coated microtiles were functionalized with a biotin SAM and a target substrate had its gold pads functionalized with an avidin SAM, the microtiles were released into a solution of phosphate buffered saline (PBS) containing a low concentration of polysorbate 20. The avidin-functionalized target substrate was then placed in this solution. Self-assembly of the microtiles onto the substrate was achieved by intermittently stirring the solution over 24 hours. In the most successful demonstration, 5 μm square microtiles were self-assembled onto patterned 5 μm square gold pads on the target substrate. After rinsing, the avidin-biotin self-assembly method yielded 2.0% of the total target pads covered by assembled microtiles at a selectivity ratio of 7.3:1 in favour of microtiles affixed to the target pads as opposed to the surrounding silicon substrate. DNA-driven self-assembly of the microtiles was also successfully demonstrated at a lower yield using similar procedures.
