Application: | Functionalized Particles have been extensively used to study cellular uptake of nanoparticles and targeted drug delivery. |
Application: | Gold nanoparticles 30 nm diameter, carboxylic acid functionalized, PEG 3000 coated, OD 50, dispersion in H2O 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. |
Application: | The carboxylic acid group binds with various proteins and are used in targeted drug delivery and gene therapy. |
Features and Benefits: | Decreases the cytotoxicity and increases efficiency of GNPs in targeted drug delivery. PEG increases the stability of the nanoparticles and prevents agglomeration. |
General description: | 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. |
Packaging: | 1 mL in poly bottle |
