The enzyme-linked immunosorbent assay (ELISA) has been an integral part of in vitro
diagnostic tests due to its high specificity, standard configuration, and convenient readout …

Based on the keen interest in biological and pharmaceutical laboratories, herein, we intend
to develop a nonenzymatic electrochemical sensor for the detection of NADH using silver …

Heavy metal contamination of water bodies has an adverse effect on human health and the
environment even at very low concentrations. In this paper, we report U-shaped fiber optic …

In the present study, a systematic investigation has been carried out for the first time to
assess the potential of three different shapes of gold nanoparticles (AuNPs), viz. nanorods …

Surface-enhanced Raman scattering (SERS) is a widely used analytical tool that allows
molecular fingerprint-based ultra-sensitive detection through an enhanced electromagnetic …

In this study, stable gold nanoparticles (AuNPs) are fabricated for the first time on
commercial ultrafine glass coverslips coated with gold thin layers (2 nm, 4 nm, 6 nm, and 8 …

Mercury and its compounds are widely distributed in the environment and have a significant
negative impact on human health. In this paper, we report the development of a rapid and …
