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.[1]

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 is used in targeted drug delivery and gene therapy. [2]
