The nanoscience revolution that sprouted throughout the 1990s is having great impact in current and future DNA detection technology around the world. In this review, we report our recent progress on gold nanoparticle based fluorescence resonance energy transfer assay to monitor DNA hybridization as well as the cleavage of DNA by nucleases. We tried to discuss a reasonable account of the science and the important fundamental work carried out in this area. We also report the development of a compact, highly specific, inexpensive and user-friendly optical fiber laser-induced fluorescence sensor based on fluorescence quenching by nanoparticles to detect single-strand DNA hybridization at femtomolar level.
