Quick and Inexpensive DNA Testing
..., the fluorescently tagged probe adsorbs on a gold nanoparticle
and its fluorescence is quenched. If the probe sequence is able to hybridize to the target, it will not adsorb on the gold and its fluorescence persists. The new method is simple and effective. It costs very little, and it's very quick. The most wi...
Link Between Nanoparticles and Kidney Stones
...s so small that some scientists question whether a nanoparticle
can live and if so, play a viable role in the development of kidney stones. The presence of proteins, RNA and DNA does not prove that nanoparticles are viable living forms because a genetic signature has not been identified, says the study’s author...
