| Abstract: | We report a hybrid singlet oxygen production system, where strong resonance coupling between plasmonic nanoparticles and photosensitizing molecules results in exceptionally high singlet oxygen production under both visible light and near‐infrared light excitation, even for the photosensitizing molecules without near‐infrared absorption. The light‐harvesting property of the plasmon‐photosensitizer hybrids leads to an enhanced, broad‐spectrum photodynamic inactivation of bacteria under a wide range of excitations, including that with near‐infrared light. |
