Detection of bacterial contaminants via frequency manipulation of amino-groups functionalized FeOnanoparticles based resonant sensor.

Bacterial infections have a large impact on public health. Through this study, we report on the development of complementary split-ring resonators (CSRR) supplemented by functionalized nanoparticles to detect bacteria in the aqueous medium. Iron oxide (FeO) nanoparticles were functionalized with amino groups using (3-aminopropyl) triethoxysilane (APTES) to form (APTES@FeO) nanoparticles, which have a specific affinity towards the bacterial species.

Sorption of brilliant green dye using soybean straw-derived biochar: characterization, kinetics, thermodynamics and toxicity studies.

The present study was aimed to investigate brilliant green (BG) dye sorption onto soybean straw biochar (SSB) prepared at 800 °C and further understanding the sorption mechanism. Sorption kinetic models such as pseudo-first and pseudo-second order were executed for demonstrating sorption mechanism between the dye and biochar. Results of kinetics study were fitted well to pseudo-second-order kinetic model (R 0.

Ampicillin-mediated functionalized gold nanoparticles against ampicillin-resistant bacteria: strategy, preparation and interaction studies.

Antibiotic resistance is a highly challenging concern of infectious diseases, and it requires a rational approach to overcome. Through this work, we have synthesized ampicillin-capped gold nanoparticles (Amp-Au NPs) and studied its interaction with bacterial cells. In this process of synthesis, the primary amine group of ampicillin acts as both reducing as well as capping agent.

Development of IFN-γ secretory ELISPOT based assay for screening of ADCC responses.

Antibody dependent cell mediated cytotoxicity has been established as one of the important protective immune mechanisms against HIV making it essential to evaluate it while testing immunogenicity of emerging vaccine candidates. IFN-γ secretory ELISPOT assay, widely used for evaluation of CTL response in HIV vaccine trials, was adapted for measuring ADCC responses and the results were compared with the standard ICS based assays. IFN-γ responses elicited by plasma samples of 23 HIV infected individuals against Env and Gag peptides using granulocytes as antigen presenting cells were assessed by both the methods.
