Sibidou Yougbare et al.

Summary: Gold-based plasmonic nanocrystals, specifically gold nanobipyramids with (111) plane, showed higher photothermal performance compared to gold nanorods with (200) plane in noninvasive photothermal therapy, as demonstrated by experimental studies and density function theory (DFT) simulations. Water desorption energy on the Au(111) surface was found to be lower than on the Au(100) surface, indicating easier desorption for photothermal heating. Additionally, AuNBPs with (111) plane exhibited higher efficiency in photothermal therapy against Escherichia coli (E. coli) under near-infrared (NIR) laser irradiation compared to AuNRs.
