Photobleaching Offers Coded Microspheres

Facebook X LinkedIn Email
Daniel S. Burgess

Using a technique they call spatial selective photobleaching, scientists at Ghent University and at Tibotec in Mechlin, both in Belgium, are producing optically encoded polymer microspheres that may find use in biomedicine, chemistry and anticounterfeiting applications. In contrast to other proposed color-coding schemes, they say, the new method yields massive numbers of unique patterns that are easily read for high throughput. Researchers typically employ 96-well plates in drug-screening applications, said Stefaan C. De Smedt of Ghent University, but these systems face physical...Read full article
