摘要：

Photothermal control of the enzymatic activity of horseradish peroxidase (HRP) bound to the surface of gold nanoparticles (AuNPs) is demonstrated. Laser light is absorbed by the AuNPs and transformed into heat, which dissipates into the environment of each nanoparticle. This heat influences the enzymatic conversion of ABTS and H2O2 to ABTS+ and H2O, respectively (see image). © 2009 Wiley-VCH Verlag GmbH & Co.
