This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials with features on the nanoscale date back hundreds of years, yet humans' ability to manipulate and control chemical systems on the atomistic level has grown immensely, particularly over the last 50 years. With expanded research capabilities, the use of nanotechnology in commercial products is also increasing, from quantum dots in television screens to novel battery materials for electric vehicles. However, along with commercialization, the risk of inadvertent release of these materials into the environment arises as well. Ecologically vital biological systems in the environment are subsequently suspectable to interaction with nanomaterials which could potentially result in harm. There are a number of complex factors associated with studying the interface between nanoparticles and cells, including nanoparticle core material, size, shape, functionalization, and transformation of the material during environmental exposure, as well as biological cell type, size, shape, and cell surface composition. As the cell membrane is likely to be the first point of contact between a cell and nanomaterial, the bacterial cell surface was modeled using phospholipids and other surface components from Gram-positive and Gram-negative bacteria. We investigated (1) cationic polymer interaction with supported lipid bilayers, as nanoparticles are often functionalized with analogous positively charged chemical groups, (2) branched polyethylenimine functionalized nanoparticle interaction with peptidoglycan and wall teichoic acids of strains of Gram-positive bacteria that differ in their wall teichoic acid composition, and (3) positively charged nanoparticle interaction with lipopolysaccharide (LPS)-containing supported lipid bilayers containing either smooth or rough LPS molecules from Escherichia coli. Using techniques sensitive to membrane surface adsorption, including quartz crystal microbalance with dissipation monitoring (QCM-D) and solid-state nuclear magnetic resonance (NMR) spectroscopy, our results demonstrate interactions between nanoparticles and cell surface structures depend on factors including electrostatic interactions, cell surface rigidity, as well as specific chemical groups present on the polycations, nanoparticles, and cell surface components. In studying the nano-bio interface on the molecular-level, the underlying goal of this research is to maintain benefit from the unique properties of nanomaterials, while reducing inadvertent negative consequences to biological systems.

Download or read book Nanostructures for Antimicrobial Therapy written by Anton Ficai and published by Elsevier. This book was released on 2017-05-29 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanostructures for Antimicrobial Therapy discusses the pros and cons of the use of nanostructured materials in the prevention and eradication of infections, highlighting the efficient microbicidal effect of nanoparticles against antibiotic-resistant pathogens and biofilms. Conventional antibiotics are becoming ineffective towards microorganisms due to their widespread and often inappropriate use. As a result, the development of antibiotic resistance in microorganisms is increasingly being reported. New approaches are needed to confront the rising issues related to infectious diseases. The merging of biomaterials, such as chitosan, carrageenan, gelatin, poly (lactic-co-glycolic acid) with nanotechnology provides a promising platform for antimicrobial therapy as it provides a controlled way to target cells and induce the desired response without the adverse effects common to many traditional treatments. Nanoparticles represent one of the most promising therapeutic treatments to the problem caused by infectious micro-organisms resistant to traditional therapies. This volume discusses this promise in detail, and also discusses what challenges the greater use of nanoparticles might pose to medical professionals. The unique physiochemical properties of nanoparticles, combined with their growth inhibitory capacity against microbes has led to the upsurge in the research on nanoparticles as antimicrobials. The importance of bactericidal nanobiomaterials study will likely increase as development of resistant strains of bacteria against most potent antibiotics continues. Shows how nanoantibiotics can be used to more effectively treat disease Discusses the advantages and issues of a variety of different nanoantibiotics, enabling medics to select which best meets their needs Provides a cogent summary of recent developments in this field, allowing readers to quickly familiarize themselves with this topic area

Download or read book Crystalline Bacterial Cell Surface Layers written by Uwe B. Sleytr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline surface layers (S-layers) represent an almost universal feature of archaebacterial cell envelopes and can be found in gram-positive and gram-negative eubacterial species from nearly all phylogenetic branches. S-layers consist of a single protein- or glycoprotein species and thus can be considered as one of the most primitive membrane structures developed during evolution. Prokaryotes carrying S-layers are ubiquitously found in every part of the biosphere. This supports the concept of a general supramolecular "porous crystalline surface layer" fulfilling a broad spectrum of functions which are strongly dependent on the particular environmental and ecological conditions. Their structural simplicity makes S-layers a suitable model for analyzing structure-function relationships as well as dynamic aspects of membrane morphogenesis.
