Thiolated Polyethylene Glycol

Photochemical reactions can cause significant transformations of manufactured nanomaterials and their surface coatings in sunlit environments. In this study, loss of thiolated polyethylene glycol from gold nanoparticle surfaces by chain scission was observed under UV irradiation and resulted in diminished colloidal stability.
