The present study attempts to demonstrate the potential of nitrogen doped carbon nanotubes for electrochemical determination heavy metal ions (especially Pb and Cd) without any prior pre-concentration step.
Metallic nanostructures are considered attractive candidates for designing novel biosensors due to their enormously significant surface area, accelerated kinetics, and improved affinity. Controllable morphological tuning of metallic on sensing interfaces is crucial attaining clinically relevant sensitivity exquisite selectivity in a complex biological environment. Therefore, facile, convenient, robust one-step electroreduction method was employed develop different variants palladium (Pd)...
Abstract The composites of IL (BmimBF 4 ) and various nitrogen doped carbon nanotubes (NCNTs) synthesized by post treatment under NH 3 at different temperatures have been explored as a novel composite material for the sensitive selective detection dopamine (DA). electrocatalytic activity these NCNTs‐IL DA was examined voltammetric rotating disc electrode (RDE) measurements. These exhibit superior sensitivity selectivity towards oxidation in presence higher concentration AA (500 µM). A linear...
The present work shows a multiplexed lab-on-printed circuit board (PCB) platform for label-free immunosensing of SARS-CoV-2 nucleocapsid and spike antigens based on electrical impedance measurements. sensor consists an interdigitated electrode soft gold integrated PCB with microwells sample loading. A mercaptoundecanoic acid–protein-G-based site-specific biofunctionalization strategy is employed to efficiently immobilize dual antibodies the device surface toward sensitive rapid antigen test...
We present a novel electrochemical biosensor for myeloperoxidase (MPO), cardiovascular disease biomarker, using gold screen printed electrodes with hierarchical nanostructures formed through in situ electrodeposition process. Incorporation of polyethylene glycol (PEG) enables immobilization desired antibodies target-specific biosensing and offers high sensitivity excellent anti-fouling capability when working complex samples such as serum. The utility this sensor is demonstrated by detection...
