PEG Gold Nanoparticles are functionalized with methoxy-terminated polyethylene glycol (PEG), offering a non-reactive and hydrophilic surface. The methoxy group prevents further conjugation, making these particles ideal for minimizing nonspecific interactions in biological systems.
Applications:
- In vivo imaging and biodistribution studies
- Development of long-circulating therapeutic nanoparticles
- Reducing background in diagnostic assays
These nanoparticles are monodisperse, optically tunable, and highly stable in complex media.
