一般描述
Carboxylic acid functionalized GNPs forms conjugates with various protein molecules due to the electrostatic attraction between negatively charged carboxylate groups and positively charged amino groups of protein.[1]
应用
Carboxylic acid functionalized, PEG 3000 coated, OD 50, and H2O dispersed gold nanoparticles (5 nm) can be potentially used in the development of biosensors, cancer-cell imaging, drug delivery, and photothermal therapy.[4]
AuNPs may be used to prepare SARS-CoV-2 conjugate for COVID-19 detection using lateral flow immunoassay technique.[5][6] It may also be used in the immobilization of antibodies to improve the sensitivity of optical fiber sensors for the screening of COVID-19.[7] It can also be deposited on the titanium electrode for the formation of a miniaturized device for the electrochemical detection of DNA hybridization.[7]
