Book Synopsis Green Nanoparticles by : Jayanta Kumar Patra
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.

Book excerpt: This dissertation presents a systematic study on gold nanoparticles: from their chemical synthesis, modification of surface functionalities, optical properties studies with emphasis on the absorption and scattering properties, to applications of gold nanoparticles in biomolecular detection, imaging and photothermal therapy. In chapter 2, we studied the kinetics of gold nanoparticle growth under Brust-Shiffrin reaction conditions. In chapter 3, we further examined the reaction mechanism and growth kinetics of gold nanoparticles using oleylamine as both a reducing reagent and particle growth passivation ligand. From these two projects, important understanding was revealed on gold nanoparticle formation and growth mechanism. Chapter 4 describes the synthesis of a monofunctional gold nanoparticle through a solid phase place exchange reaction. From Chapter 5, we moved to the optical property study of gold nanoparticles, particularly the absorption and scattering phenomenon. In this work a systematic analysis on the extinction coefficient of gold nanoparticles was performed, providing meaningful references for applications based on optical absorption properties of gold nanoparticles. In Chapter 6 and Chapter 7, we developed a one-step homogeneous immunoassay for protein detection and analysis based on the strong light scattering of gold nanoparticles and dynamic light scattering detection technique. In Chapter 8, we further improved the stability of gold nanoparticle bioconjugates using a poly(ethylene glycol)-coated gold nanoparticles and further tested this nanoparticle in the one-step homogeneous immunoassay. Finally in Chapter 9, we demonstrated the application of gold nanoparticles for in vitro bioimaging and photothermal therapy of a lung cancer cell. In summary, this dissertation presents a comprehensive study on the synthesis, surface modification, property study of gold nanoparticles and their applications in biomolecular imaging and analysis.
Book Synopsis Development of Gold Supraparticles for Nanomedicine Applications by : Surreya Paterson
Download or read book Development of Gold Supraparticles for Nanomedicine Applications written by Surreya Paterson and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold nanoparticles are widely used in bionanotechnology due to their unique optical properties and ease of surface modification with biomolecules. By assembling these gold nanoparticles into ordered structures their physiochemical properties can be fine-tuned. Gold nanoparticle assemblies have shown a remarkable increase in surface enhanced Raman signals (SERS) which can be further used for biological sensing applications. In addition, their efficient conversion of light to heat energy allows them to be promising candidates for photothermal therapies. A new method for assembling citrate capped gold nanoparticles into crystallographically aligned supraparticles is reported. These are biocompatible and have a strong SERS response. Additionally, these have been shown to convert light to heat more efficiently than their nanoparticle building blocks. Furthermore, gold nanoparticles were assembled onto a superparamagnetic iron oxide (SPION) core. These anisotropic assemblies called suprashells have a plasmon band in the near-infrared (NIR) region which makes them suitable candidates for biological applications. They also make efficient thermal transducers and promising SERS substrates due to the enhancement of signal. Finally, self-assembled structures of monomer fluorenylmethyloxycarbonyl (Fmoc) protected amino acids are used as potential templates for gold nanoparticle assemblies. Each Fmoc-amino acid assembles into its own unique structure depending on the intrinsic property of its side chain. These soft templates are used to guide the assembly of gold nanoparticles. It has been found that there is a symbiotic relationship between the gold nanoparticle and amino acid side chain which can dictate the final degree of order.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique properties of gold nanoparticles make them excellent candidates for applications in electronics, sensing, imaging, and photothermal therapy. Though abundant literature exists for isotropic gold nanoparticles, work on nanoparticles of different shapes has been gaining interest recently. Anisotropic gold nanoparticles, such as nanorods and nanoprisms, have tunable optical properties in the visible and near-infrared regions. Through synthesis and surface modification, the production of various shapes of these gold nanoparticles can be controlled to meet different applications. Two different types of gold nanorods were used in this thesis. The first type was stabilized with cetyltrimethylammonium bromide (CTAB) and had aspect ratios of 3-4 (defined as the nanorod length divided by the diameter). The second type was synthesized using CTAB and benzyldimethylhexadecylammonium chloride (BDAC) in a binary surfactant system which produced aspect ratios greater than 4. The nanorods were characterized with UV-Vis spectroscopy and transmission electron microscopy (TEM). Two types of bowl-shaped macrocyclic compounds called resorcinarenes were used to direct self-assembly of the nanorods. The first type of resorcinarene (R2S) consisted of thiol(SH)-terminated alkyl chains on both rims. The second type (R1S) contained thiol-terminated alkyl chains on only one rim. The monolayer formation of these resorcinarenes on planar gold surfaces was studied and characterized by FTIR spectroscopy. Resorcinarene-mediated assembly of gold nanorods was monitored with UV-Vis spectroscopy, dynamic light scattering (DLS), and TEM. In addition to gold nanorods, gold nanoprisms were synthesized through a kinetically-controlled reduction route in the presence of CTAB. The linking of nanoprisms using resorcinarenes was also explored.

Download or read book Surface Engineering of Gold Nanoparticles and Their Applications written by Qiu Dai and published by . This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold nanoparticles (AuNPs) with their unique sizes, shapes, and properties have generated much enthusiasm over the last two decades, and have been explored for many potential applications. The successful application of AuNPs depends critically on the ability to modify and functionalize their surface to provide stability, compatibility, and special chemical functionality. This dissertation is aimed at exploring the chemical synthesis and surface modification of AuNPs with the effort to (1) control the number of functional groups on the particle surface, and to (2) increase the colloidal stability at the physiological conditions. To control the functionality on the particle surface, a solid phase place exchange reaction strategy was developed to synthesize the 2 nm AuNPs with a single carboxylic acid group attached on the particle surface. Such monofunctional AuNPs can be treated and used as molecular nanobuilding blocks to form more complex nanomaterials with controllable structures. A "necklace"--Like AuNP/polymer assembly was obtained by conjugating covalently the monofunctional AuNPs with polylysine template, and exhibited an enhanced optical limiting property due to strong electromagnetic interaction between the nanoparticles in close proximity. To improve the colloidal stability in the psychological condition, biocompatible polymers, polyacrylic acid (PAA), and polyethylene glycol (PEG) were used to surface modify the 30 nm citrate-stabilized AuNPs. These polymer-modified AuNPs are able to disperse individually in the high ionic strength solution, and offer as the promising optical probes for bioassay applications. The Prostate specific antigen (PSA) and target DNA can be detected in the low pM range by taking advantages of the large scattering cross section of AuNPs and the high sensitivity of dynamic light scattering (DLS) measurement. In addition to the large scattering cross section, AuNPs can absorb strongly the photon energy at the surface plasmon resonance wavelength and then transform efficiently to the heat energy. The efficient photon-thermal energy conversion property of AuNPs has been used to thermal ablate the A[beta] peptide aggregates under laser irradiation toward Alzheimer's disease therapy.
