Soft biological tissue is almost completely transparent to short-wave infrared (SWIR) light but nanoscale probes emitting at these wavelengths that can be injected into the body are still lacking. A team of researchers in the US and Germany has now overcome this problem with a new class of SWIR-emitting indium-arsenide-based quantum dots. Thanks to their intense brightness, the dots could be used to obtain detailed images of internal body structures like fine networks of blood vessels….
