BIOMEDICAL IMAGING/NANOTECHNOLOGY: Extreme low-light imaging to benefit from photodetector material

Ultrathin "nanosheets" -- indium selenide (In2Se3)-based material made of highly efficient nano-sized light detectors -- could provide a huge benefit to low-light biomedical imaging, and with little cost.

"Future cameras based on these nanosheet photodetectors may be able to provide a robust, real-time picture in even the most extreme low-light conditions," said SUNY College of Nanoscale Science and Engineering (CNSE; Albany, NY) research assistant Robin Jacobs-Gedrim, who is first author on a paper describing the development.1 The CNSE innovation could lead not only to more efficient imaging devices, but also impact smartphones along with many other everyday devices. End results could include improved healthcare outcomes and new biomedical discoveries.
