Collaborating with School of Life Sciences at UJS and INRS of Canada, IQST research team shows exciting results of Plasmonic nanostructures as nanomedicine for efficient tumor treatment. Plasmonic nanohybrids are promising photo energy conversion materials in photoelectronics and biomedicine due to their unique surface plasmon resonance (SPR) property. Au and Cu2-xSx nanostructures with strong SPR in the near-infrared (NIR) spectral region are classic plasmonic systems used to convert NIR photons into heat for photothermal therapy (PTT).
The joint research team reports a synthesis of AuCu Star/Cu2-xSx nanohybrid, where the Cu2-xSx components are selectively grown on the tips of the AuCu nanostar to form “caps”. The nanohybrids show low cytotoxicity and superior photothermal conversion efficiency, enabling robust PTT to kill cancer cells in the second NIR window. Numerical simulation reveals that the coupling of Cu2-xSx on nanostar tips generates a strong interfacial electric field, improving photothermal conversion. This work has been accepted by the international journal of Small recently.
