Scientists are developing technology inspired by butterflies.

GE has received a million dollar grant by DARPA to develop nanostructured sensors that would allow quick detection of dangerous chemical threats. GE scientists had earlier discovered that nanostructures from butterflies’ wing scales have sharp chemical sensing properties, which they were trying to replicate in a new bio-inspired sensing platform. While GE’s sensing technology would be helpful in improving homeland security, scientists working on it say that their nano-sensors may also have industrial applications such as monitoring food and beverage safety, emissions and water purification testing.
