Researchers at Karolinska Institutet in Sweden have
developed a tiny sensor for detecting pesticides on fruit in just a
few minutes. The technique, described as a proof-of-concept in a
paper in the journal Advanced Science, uses flame-sprayed
nanoparticles made from silver to increase the signal of chemicals.
While still at an early stage, the researchers hope these
nano-sensors could help uncover food pesticides before
consumption.

The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
