title: Photochemistry. Twist and fluoresce.
abstract: Catalytic antibodies, or artificial enzymes, act as catalysts by lowering the energy of the transition state of a reaction. In his Perspective, Brauman highlights the study by Simeonov et al., who have applied similar principles to photochemical processes and shown that intense fluorescence can be achieved. The approach provides a way of measuring internal molecular motion within the antibody on a very fast time scale. Fluorescent antibodies may find applications in immunochemistry, histological assays, and genomic studies.
