FocusThe activity is focused on the development of single-photon avalanche diodes (SPADs) and associated electronic instrumentation and systems for low-light-level detection, with special attention to applications in life-science, such as micro- and nano-analytical techniques for biomedical and genetic diagnostics, and high-sensitivity and high frame-rate imaging, like 2D spectroscopy and 3D time-of-flight ranging. A driving force is the widespread interest to rapid and efficient detection of fluorescent emission from extremely small biological samples down to single molecules of DNA and proteins. Main goal is the development of new miniaturized detection systems that overcome drawbacks and limitations of existing systems, which rely on bulky and costly equipment and discrete sensors. High attention and remarkable efforts are devoted to imaging with ultrafast time-resolved capability at single-photon level with array detectors in linear and 2D geometries.
