Researchers have designed a new small-molecule probe that binds to a protein and emits a fluorescent signal only when a drug molecule displaces it (J. Am. Chem. Soc., DOI: 10.1021/ ja301204z). The chemists hope that the probe will provide a simple, rapid method to screen drug candidates.

“There is a need for easy systems for screening drugs,” says . . .
