应用

The carboxylic acid group may be used to bind with various proteins and can be used in targeted drug delivery and gene therapy.
Carboxylic acid functionalized, PEG 3000 coated, OD 50, and H2O dispersed gold nanoparticles (50 nm) 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.
Functionalized Particles have been extensively used to study cellular uptake of nanoparticles and targeted drug delivery.

包装

1 mL in poly bottle

特点和优势

Decreases the cytotoxicity and increases efficiency of GNPs in targeted drug delivery. PEG increases the stability of the nanoparticles and prevents agglomeration.
