    Abstract

    Gold nanorods were modified with two types of doublestranded DNAs (dsDNA) with different melting temperatures. Irradiated by near-infrared laser light, the modified gold nanorods were heated, and single-stranded DNAs were released faster from the dsDNAwith the lower melting temperature. Such combinations of different kinds of dsDNA allow us to construct a two-step release system of different types of oligonucleotides.
