Advance could aid development of nanoscale biosensors

Imagine a hand-held environmental sensor that can instantly test water for lead, E. coli, and pesticides all at the same time, or a biosensor that can perform a complete blood workup from just a single drop. That's the promise of nanoscale plasmonic interferometry, a technique that combines nanotechnology with plasmonics - the interaction between electrons in a metal and light.

Light used to measure the 'big stretch' in spider silk proteins

While working to improve a tool that measures the pushes and pulls sensed by proteins in living cells, biophysicists at Johns Hopkins say they've discovered one reason spiders' silk is so elastic: Pieces of the silk's protein threads act like supersprings, stretching to five times their initial length.
