JANUARY 5TH, 2023 CONN HASTINGS DIAGNOSTICS, ENT, ONCOLOGY Researchers at the University of Florida have created a point-of-care biosensor that can rapidly detect a biomarker for oral cancer. The device uses test strips, such as those used in blood glucose tests, to spot cell proliferation regulating inhibitor of protein phosphatase 2A (CIP2A), a protein biomarker that can...
by American Chemical Society Graphical abstract. Credit: ACS Nano (2022). DOI: 10.1021/acsnano.2c04187 Despite significant advances, mortality from brain tumors remains high with five-year survival rates of 36%, according to the National Cancer Institute. More accurate diagnoses might improve the situation, but tissue biopsies are invasive and can miss important information about a tumor’s make-up. Imaging-based methods, meanwhile,...
Scientists have successfully tested in the lab a tiny biosensor they developed that can detect biomarkers tied to traumatic brain injuries. In a study published recently in the journal Small, the Ohio State University researchers say their waterproof biosensor includes an “unprecedented combination of features” that may allow it to detect changes in the concentrations of various...

Buscaglia/IFSC-USP The challenges posed by the COVID-19 pandemic have stimulated innovation on several fronts. One is the development of low-cost methods of clinical diagnosis. Genosensors are a case in point. Based on nucleic acids that...
Posted Today Assistant professor of medical engineering Wei Gao is enriching the field of personalized and precision medicine with an abundant source of chemical data: sweat. Gao’s perspiration-analysis technology enables early detection of physiological aberrations, customized treatment plans, and greater accuracy in drug monitoring. Low energy, for example, is a symptom that could be associated with a multitude of...
The iQ Group Global, an Australian consortium, has announced that it developed a biosensor capable of accurately measuring glucose in a person’s saliva. The technology, originally acquired from the University of Newcastle in Australia, uses modified organic thin film transistors, which work in combination with glucoseoxidase, to measure the concentration of glucose in a sample. The complete system consists of a Glucose Biosensor Unit, which does the measurements, and...
