Nanoplasmonics - making a tiny rainbow

A scheme for greatly increasing the number of colors that can be produced by arrays of tiny aluminum nanodisks has been demonstrated by A*STAR scientists ("Plasmonic Color Palettes for Photorealistic Printing with Aluminum Nanostructures"). Three strategies for producing colors of pixels containing four aluminum nanodisks. Row 1: varying the nanodisk...

Nonprofits sue EPA for failure to regulate pesticide products created with nanotechnology

Center for Food Safety (CFS) filed a lawsuit (pdf) last month against the U.S. Environmental Protection Agency (EPA) over the agency’s failure to regulate novel nanomaterial pesticides. In 2008 CFS filed a legal petition (pdf) demanding the agency take action; today nonprofits sued the agency for its...

New microcapsules have potential to repair damage caused by osteoarthritis

A new 'microcapsule' treatment delivery method developed by researchers at Queen Mary University of London (QMUL) could reduce inflammation in cartilage affected by osteoarthritis and reverse damage to tissue ("Controlled release of C-type natriuretic peptide by microencapsulation dampens pro-inflammatory effects induced by IL-1β in cartilage explants")....

A highly sensitive nanoplasmonic biosensor for drug allergy diagnosis

The new technique is a non-invasive procedure to detect the severity of an allergic reaction to amoxicillin. The developed biosensor platform is based on gold nanodisks, is very sensitive and works label-free, detecting the changes in the refraction index occurring at its surface after the binding of IgEs specific for amoxicillin. The bio applications...
