Bio-gold Nanoparticle Synthesis by Metalophilic Bacterium Cupriavidus necator
Background and Aims: Gold nanoparticles have potential applications in the areas of medicine, target drug delivery, cancer diagnosis and therapy, electronic, etc. Recently, biological system is considered as an environmental friendly method for synthesis of stable nanoparticles. Methods: We demonstrated a biological system for formation of stable gold nanoparticle by using Cupriavidus necator w...
متن کاملSelf Trapping of a Single Bacterium in its Own Chemoattractant
– Bacteria (e.g. E. Coli) are very sensitive to certain chemoattractants (e.g. asparate) which they themselves produce. This leads to chemical instabilities in a uniform population. We discuss here the different case of a single bacterium, following the general scheme of Brenner, Levitov and Budrene. We show that in one and two dimensions (in a capillary or in a thin film) the bacterium can bec...
متن کاملReal-time RNA profiling within a single bacterium.
Characterizing the dynamics of specific RNA levels requires real-time RNA profiling in a single cell. We show that the combination of a synthetic modular genetic system with fluorescence correlation spectroscopy allows us to directly measure in real time the activity of any specific promoter in prokaryotes. Using a simple inducible gene expression system, we found that induced RNA levels within...
متن کاملSingle-Setup-Multiple-Deliveries for a Single Supplier-Single Buyer with Single Product and Backorder
This article investigates integrated production-inventory models with backorder. A single supplier and a single buyer are considered and shortage as backorder is allowed for the buyer. The proposed models determine optimal order quantity, optimal backorder quantity and optimal number of deliveries on the joint total cost for both buyer and supplier. Two cases are discussed: single-setup-singl...
متن کاملA fluorescent nanoprobe for single bacterium tracking: functionalization of silver nanoparticles with tryptophan to probe the nanoparticle accumulation with single cell resolution.
The investigation of the interaction of silver nanoparticles and live bacteria cells is of particular importance for understanding and controlling their bactericidal properties. In this study, the process of internalization of silver nanoparticles in Escherichia coli cells was followed by means of synchrotron excitation deep ultraviolet (DUV) fluorescence imaging. Antimicrobial nanostructures t...
