based on hollow Au nanostructures have gained considerable
attention in theranostics applications because of their unique plasmonic
structures and attractive physicochemical properties. The exploration
of feasible and facile methods for constructing multifunctional nanocomposites
combined with bioactive molecules is greatly needed for the development
of multifunctional theranostics platforms. In this work, resveratrol,
a natural polyphenol with antioxidant activity and cancer-chemopreventive
propertyies is employed as the reducing agent cum coating agent for
the surfactant-free preparation of Au@resveratrol hollow NPs (Au@Res
HNPs). The as-prepared Au@Res HNPs were found to present good photothermal
performance and chemical inhibition for cancer therapy. In vitro experiments
indicated that the Au@Res HNPs can block cell cycles to inhibit cell
division and lead to cell apoptosis after 808-nm laser irradiation.
Because no toxic surfactants are introduced, the current protocol
avoids the tedious surfactant separation and surface modification
processes that are necessary for most theranostics materials.
