一般說明
Carboxylic acid functionalized GNPs form conjugates with various protein molecules due to the electrostatic attraction between negatively charged carboxylate groups and positively charged amino groups of protein.[1]
應用
Carboxylic acid functionalized, PEG 5000 coated, OD 50, and H2O dispersed gold nanoparticles 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]

The carboxylic acid group binds with various proteins and can be used in targeted drug delivery and gene therapy. [8]
特點和優勢
Decreases the cytotoxicity and increases efficiency of GNPs in targeted drug delivery. The PEG increases the stability of the nanoparticles and prevents agglomeration.[8]
