Silicon photomultiplier (SiPM) detectors operated in Geiger mode are recently enabling a wide variety of biophotonics applications due to several advantageous features over traditional photomultiplier tubes. Silicon photomultiplier technology combines highly sensitive photon counting with miniaturized packaging, providing portability, low voltage operation, immunity to magnetic field...
Inadequate oxygen delivery to the brain is a major cause of cerebral injury. Near-infrared spectroscopy (NIRS) is a portable and non-invasive technique that can detect brain injury by monitoring cerebral oxygenation. However, the use of NIRS for adult neuromonitoring has been stymied by significant signal contamination from their thick (~10mm) extracerebral layers (ECL; scalp and skull)....
The experimental discovery of graphene has largely relied on making it visible by optical microscopes when deposited on silicon wafers coated by a 300-nm SiO2 layer, leading to constructive optical interference in the visible photon energy range [1]. While such a discovery has enabled exciting new areas of research, so many of them do not use graphene on 300-nm SiO2/Si. Thus, methods to image...
The analysis of human nail clippings to determine the concentration of certain elements is often used to assess exposure to elements and their absorption into the body. When nail clippings are used as a biomarker, they are usually analyzed by a “gold standard” method such as inductively coupled plasma-mass spectrometry (ICP-MS). Our group has investigated the use of a novel portable X-ray...
