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 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.

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.

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.
