Development of highly sensitive electrochemical immunosensor using PPy-MoS-based nanocomposites modified with 90 MeV C ion beams.

The evaluation of electrochemical sensing activity of hydrothermally derived PPy-MoS-based nanocomposites subjected to 90 MeV C ion beam with fluence ranging, 1.0 × 10-1.0 × 10 ions/cm, is reported.

Electrochemically deposited bimetallic SERS substrate for trace sensing of antibiotics.

Electrochemically deposited bimetallic copper-gold nanoparticles on indium tin oxide (Cu-AuNPs on ITO) glass are demonstrated to be a sensitive and reproducible surface-enhanced Raman scattering (SERS) platform. An optimal signal enhancement with reasonably good degree of homogeneity was obtained by tuning the deposition parameters of the electrochemical setup. For Raman active analytes such as malachite green (MG) and rhodamine 6G (R6G), the developed SERS platform yields a limit of detection (LOD) of 0.
