Ultrafast and ultra-sensitive protein detection method allows for early disease diagnoses

Protein detection based on antigen–antibody reactions is vital in early diagnosis of a wide range of diseases. How to effectively detect proteins, however, has frequently bedeviled researchers. Osaka Metropolitan University scientists have discovered a new principle underlying light-induced acceleration of the antigen–antibody reaction, allowing for simple, ultrafast, and highly sensitive detection of proteins. Their findings were published in Communications Biology.
