Fabrication of red blood cell membrane-camouflaged Cu2−xSe nanoparticles for phototherapy in the second near-infrared window†
Abstract
Cu2−xSe nanoparticles (Cu2−xSeNPs) were camouflaged with a red blood cell membrane (RBC) to create nanoparticles with improved biocompatibility, longer blood retention times, excellent absorption properties, superior photothermal conversion efficiency (67.2%) and singlet oxygen production capabilities for the synergistic photothermal and photodynamic therapy of cancer in the second near-infrared (NIR-II) window.
