Plasmonics has the potential to boost the efficiency of several technologies, from catalysis to solar cells. To this day, most plasmonic materials are made based on a trial and error approach. In this article published in the Journal of Physical Chemistry Letters, PhD students Nicolas Macia and Vladimir Kabanov, and RISE intern Mélanie Côté-Cyr working in Dr. Belinda Heyne's group established a set of guidelines in the design of hybrid metal nanoparticles used as plasmonic platforms for enhancing the singlet oxygen production of common photosensitizer molecules that are promising candidates as more efficient antimicrobial agents.
