Abstract
Deep tissue imaging has been limited by the low brightness of probes emitting in the second near-infrared window. Here, the authors use femtosecond laser irradiation to grow a protective shell on Ag2S nanoparticles, achieving 80-fold quantum yield enhancement and imaging with low excitation intensities.
