Description

Application

Functionalized Particles have been extensively used to study cellular uptake of nanoparticles and targeted drug delivery.

The carboxylic acid group binds with various proteins and can be used in targeted drug delivery and gene therapy.

Packaging

1 mL in poly bottle

Features and Benefits

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

General description

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.
