Proteins (IMAGE) Max-Planck-Gesellschaft Caption Researchers from Erlangen can identify individual unlabeled proteins by the weak shadow that the biomolecules produce when they scatter light. For their biosensor, the scientists use a very sensitive method to detect scattered light. In addition, they have found a way to suppress the disturbing optical background noise.
