Making biomolecules glow: New dye solves imaging interference problem

Phys · · 354 words · By University

Researchers at the University of Göttingen have developed a new method for labeling biomolecules with luminescent dyes that only glow upon binding to the target. This approach reduces imaging interference caused by unbound dyes and has been demonstrated across various biomolecular structures and cellular imaging.
