Clemson researchers create biosensors to protect nation's food and water supplies

...ng food or water that has been contaminated. "The nanoparticle can move into crevices in the food source, where a pathogen could be hidden from microscopic view," Dawson said. "The particle's extremely small size increases the odds that the antibody and antigen will link, enabling the sensor to give off a glow. ...

Non-invasive imaging technique detects plaques beginning to form in vessels

...ted only new capillaries, the team also packed the nanoparticle with molecules that specifically detect a protein called avb3, which is abundant in rapidly growing capillaries. In so doing, the nanoparticles mainly latched onto cells that contain avb3. "You can load these nanoparticles with whatever you want, lik...

Beyond patches and pills: the remarkable future of drug delivery

...efore they start. To this end, they are developing nanoparticle sensors -- tiny particles on the order of a single atom that will recognize compounds, such as glucose and cholesterol, whose overproduction may signal disease. The particles will then trigger a mechanism that tells a system (like the pharmacy on a c...
