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...

Now, Silica Nanobubbles for Targeted Drug Delivery

...loxacin (a known antibiotic) molecules on the gold nanoparticle surface with subsequent growth of a silica shell over that. This was followed by removal of the gold core -- using a method they have patented -- leaving behind a "nanobubble" inside which the antibiotic was trapped. "A hollow nanobubble or nanoshe...

New Multi-Modal Contrast Agents, A Boon For Medical Imaging

...M&M candy -- functions as a spacer, preventing the nanoparticle from undergoing a chemical reaction when it comes in contact with water. It also keeps the nanoparticles from clumping and behaving erratically. ‘The M&M analogy is really a great one because it says you can put things on the outside and you can ha...
