New biosensor can detect dopamine in unprocessed blood samples

Researchers at the University of Central Florida have developed a new, cost-effective biosensor capable of rapidly detecting and measuring dopamine levels directly from unprocessed blood samples. This innovation could help diagnose and monitor Parkinson’s disease and other conditions related to abnormal dopamine levels, particularly in remote areas without access to complex lab equipment. The sensor uses a synthetic DNA molecule called an aptamer, which binds to dopamine with high specificity, offering a faster and more accurate alternative to current methods that require complex procedures. The sensor’s design also makes it more affordable and easier to store compared to traditional biosensors. Researchers hope it can advance medical diagnostics and treatments.
