Oligochitosan-stabilized photoluminescent gold nanoconstructs for optical bioimaging
2017
Background
Gold nanoclusters (AuNCs) are typically composed of several to tens of gold atoms which are stabilized with biomacromolecules such as bovine serum albumin (BSA). Au NCs fluoresces in the visible to near infrared region, in a size-dependent manner. AuNCs solutions have potential as fluorophore in a wide range of biomedical applications such as biodetection, biosensing and bioimaging in vitro and in vivo. However, their stability and harsh condition of preparation limit their biomedical application.
