Description

Application

NHS ester functionalized gold nanoparticles conjugation kit (15 nm) can be used in the surface modification of indium tin oxide (ITO) electrodes for potential usage in electrocatalysis, and electrochemical sensing.
AuNPs may be used to prepare SARS-CoV-2 conjugate for COVID-19 detection using lateral flow immunoassay technique. It can be potentially used in immobilization of antibodies to improve the sensitivity of optical fiber sensors for the screening of COVID-19. It can also be deposited on the titanium electrode for the formation of a miniaturized device for the electrochemical detection of DNA hybridization.
