Researchers Investigate Remote Control of Enzymes Using Laser Light
Written by AZoOpticsMar 17 2021
The activity of enzymes in industrial processes, laboratories, and living beings can be remotely controlled using light. This requires their immobilization on the surface of nanoparticles and irradiation with a laser.
Near-infrared light can penetrate living tissue without damaging it. The nanoparticles absorb the energy of the radiation and release it back in the form of heat or electronic effects, triggering or intensifying the enzymes catalytic activity. This configures a new field of study known as plasmonic biocatalysis.
Research conducted at the University of São Paulo s Chemistry Institute (IQ-USP) in Brazil investigated the activity of enzymes immobilized on gold nanoparticles controlled by infrared laser irradiation. An article reporting the results is published in
