Fluorescent nanoparticles guide the way in a single living cell
Scientists from the University of Twente have successfully exploited the optical properties of fluorescent nanoparticles to broaden the scope of single-cell microscopy. By using nanoparticles, they succeeded in combining two different optical microscopy techniques on the same cell. This opens exciting new possibilities for cellular imaging.

Gold Nanoparticles Help Detect a Toxic Metal: Mercury
With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources.

Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer
A cancer-suppressing gene has been successfully delivered into the tumors of stage 4 lung cancer patients via an intravenously administered lipid nanoparticle in a phase I clinical trial at The University of Texas M. D. Anderson Cancer Center. The gene, FUS1, also was found to be active in the metastatic non-small cell lung cancer tumors.

Nanoparticles can track cells deep within living organisms
To the delight of researchers at Washington University School of Medicine in St. Louis, living cells gobbled up fluorine-laced nanoparticles without needing any coaxing. Then, because of the unusual meal, the cells were easily located with MRI scanning after being injected into mice.

Watery Nanoparticles Deliver Anticancer Therapy
Ultrafine nanoparticles made of a lacy web of polymer and tiny pockets of water may prove to be an ideal vehicle for delivering light-activated drugs to tumors. Preliminary experiments, published in the journal Angewandte Chemie International Edition, show that cancer cells die quickly when treated with these nanoparticles and exposed to light.
