Novel biosensor could help optimise cancer treatment

Drug Discovery World

Scientists from Korea have developed a new biosensor that uses fluorescence resonance energy transfer (FRET) to detect DNA double-strand breaks in living specimens in real time. This biosensor has the potential to aid the development of new treatments for DNA damage-related diseases by revealing how our bodies repair damaged DNA.
