The discovery of unexpected magnetic interactions between ultrasmall specks of rust is leading scientists at Rice University's Center for Biological and Environmental Nanotechnology (CBEN) to develop a revolutionary, low-cost technology for cleaning arsenic from drinking water.   view more (2006-11-10)

Brown Chemists Create Cancer-Detecting Nanoparticles
A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the particles emit stronger signals that MRI scans can... view more... (2008-05-28)

Gold nanoparticles could improve antisense cancer drugs
In the fight against cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow.   view more (2006-05-19)

Therapeutic nanoparticles give new meaning to sugar-coating medicine
A research team at the National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be.   view more (2009-09-23)

Rice fine-tunes attack on cancer
Two lasers may be better than one when attacking cancer cells, according to a paper by Rice University scientists.    view more (2009-03-26)

Safer nanoparticles spotlight tumors, deliver drugs
Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless by-products.   view more (2009-02-23)

Topical erectile dysfunction therapy shows promise
An innovative drug-delivery system - nanoparticles encapsulating nitric oxide or prescription drugs - shows promise for topical treatment of erectile dysfunction (ED), according to a new study by scientists at Albert Einstein College of Medicine of Yeshiva University.   view more (2009-09-21)
