Brazilian researchers have developed an electrochemical sensor that can detect pancreatic cancer in its early stages. The device identifies the biomarker molecule CA19-9, which is associated with the ...
Hand-held biosensor using saliva sample makes breast cancer screening fast, affordable, and accurate
Breast cancer is on the rise, but new tools for early detection could save lives. In Journal of Vacuum Science & Technology B, researchers from the University of Florida and National Yang Ming Chiao ...
Surface plasmon resonance (SPR) is an optical methodology widely used to detect and quantify molecular interactions. SPR is considered the gold standard for quantification of protein interactions, but ...
Schematic of a generic biosensor architecture. The target analyte interacts with an immobilized bioreceptor layer, and the resulting molecular recognition event is translated by a physico-chemical ...
Wearable and implantable biosensors that can accurately detect biological molecules in a non- or minimally invasive manner have vast potential for monitoring patients' physiology and response to ...
Since its origins in the 1960s, the biosensors field has grown to encompass a wide range of sensors, from enzyme-based to immunosensors to thermal biosensors. Along with this, a diverse set of ...
Scientists can do some nifty things with microbes, including engineering bacterial cells to sense and signal the presence of specific compounds. These microbial whole-cell biosensors have numerous ...
