Journal ArticleDOI
The chemical and structural analysis of graphene oxide with different degrees of oxidation
TL;DR: In this article, the formation of different types of oxygen containing functional groups in GO and their influences on its structure were analyzed using X-ray diffraction (XRD), Fourier transform infra-red spectra, x-ray photoelectron spectra (XPS), zeta potential analysis and Raman spectroscopy.
Journal ArticleDOI
Antibacterial Efficiency of Graphene Nanosheets against Pathogenic Bacteria via Lipid Peroxidation
TL;DR: The minimum inhibitory concentration (MIC) of Graphene nanosheets against pathogenic bacteria was evaluated by a micro-dilution method in this article, which showed that 1 μg/mL (against Escherichia coli and Salmonella typhimurium).
Journal ArticleDOI
Biosynthesis of silver nanoparticles by Streptomyces hygroscopicus and antimicrobial activity against medically important pathogenic microorganisms.
TL;DR: Biological reduction of aqueous silver ions by extracellular components of Streptomyces hygroscopicus could be employed as a potential nanomedicine to eliminate pathogenic microorganisms.
Journal ArticleDOI
Fluorescent Gold Nanoclusters for Selective Detection of Dopamine in Cerebrospinal fluid.
TL;DR: Stable, nontoxic and red fluorescent emission BSA-Au NCs for selective detection of L-dopamine (DA) in cerebrospinal fluid (CSF) and as-prepared BSA -AuNCs will gain possible strategy and good platform for biosensor, drug discovery, and rapid disease diagnosis such as Parkinson’s and Alzheimer diseases.
Journal ArticleDOI
Synthesis, characterization and electrochemical properties of functionalized graphene oxide
TL;DR: Graphene oxide (GO) was functionalized by a simple reaction of its carboxylic acid groups with a silanized-metalloid polymer, which gave the resulting hybrid GO the property of efficient dispersion in a variety of solvents as discussed by the authors.
