Light-Triggered Self-Assembly of Gold Nanoparticles Based on Photoisomerization of Spirothiopyran

摘要

Gold nanoparticles (AuNPs) are unique building blocks with sophisticated optical, electronic and chemical properties that differ dramatically from those of the bulk metal. They have potential for cancer diagnosis and therapy on account of their surface plasmon resonance (SPR) enhanced light scattering and absorption properties. Owing to their high surface-to-volume ratio and high surface energy, AuNPs exhibit unusual catalytic and photocatalytic activities as well as electronic properties These properties are strongly size-dependent therefore, accurate size control of AuNPs is a challenge for advanced processing of AuNPs.
