摘要：

Plasmid DNA was immobilized on positively-charged gold nanoparticles (GNPs). Pulsed-laser irradiation induced fragmentation and dissociation of DNA from the GNP-DNA complexes. Dissociation of DNA without degradation was achieved when 80- mJ/pulse of laser light irradiated the GNP-DNA complexes.
