Abstract:

Nanotechnology has allowed various coatings and modifications to nanostructures for applications of biomedicine. The constructions of simple, economical, controllable and biocompatible drug delivery systems(DDS) are still in demand. Here, we report a NaYF4：Yb/Tm nanoparticle-based DDS that anticancer drug doxorubicin(Dox) could be quantitatively carried by double stranded DNA thereon that self-assembled through a hybridization chain reaction(HCR). The HCR DNA was absorbed on the surface of upconversion nanoparticles(UCNPs) through linkage to photocleavable 1-(4,5-dimethoxy-2-nitrophenyl) diazoethane(DMNPE) molecules, which can be cleaved by near ultraviolet light emitted by UCNPs under 980 nm laser light excitation. The controllable release of model drug Dox by near-infrared(NIR) should facilitate selective cytotoxicity to target region and reduced side effects and could prove promising in biomedical applications.

Key words: upconversion nanoparticles, DNA hybridization chain reaction, controllable release, doxorubicin hydrochloride
