Biosensor (IMAGE) University of California - Santa Barbara Caption By mimicking natural sensors, Vallée-Bélisle, Ricci and Plaxco have created biosensors that are highly precise (ideal for monitoring the concentration of highly toxic drugs used to treat many cancers) or that can detect a very large change in target concentrations (ideal to monitor HIV virus progression). The researchers believe that these strategies can be applied to a wide range of biosensors, which may significantly impact efforts to build better point-of-care biosensors for the detection of disease biomarkers.
