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.
應用
Carboxylic acid functionalized, PEG 3000, OD 50, and H2O dispersed gold nanoparticles (10 nm) (AuNPs) can be potentially used in the development of biosensors, cancer-cell imaging, drug delivery, and photothermal therapy. AUNPs may also be used in the 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.
The carboxylic acid group binds with various proteins and is used in targeted drug delivery and gene therapy.
功能化颗粒已被广泛用于研究纳米颗粒的细胞摄取和靶向药物递送。
