Advice to my younger self
If I were to start all over again, I would focus on the development of cutting-edge analytical technologies, and the application of these technologies to address major chemical and biomedical problems.
My proudest moment came 20 years ago, when my student Steve Emory and I discovered “hot” nanoparticles that were able to amplify the efficiency of surface-enhanced Raman scattering (SERS) by 14–15 orders of magnitude.
Biggest game changers
The biggest breakthroughs in nanoscale science have been the development of semiconductor quantum dots, plasmonic nanostructures, and smart stimuli-responsive nanoparticle imaging probes.
