Effective Targeted Photothermal Ablation of Multidrug Resistant Bacteria and Their Biofilms with NIR‐Absorbing Gold Nanocrosses

With the rapid evolution of antibiotic resistance in bacteria, antibiotic‐resistant bacteria (in particular, multidrug‐resistant bacteria) and their biofilms have been becoming more and more difficult to be effectively treated with conventional antibiotics. As such, there is a great demand to develop a nonantibiotic approach in efficiently eliminating such bacteria. Here, multibranched gold nanocrosses with strong near‐infrared absorption...
