On the Trail of Proteins: Scientists electrochemically detect protein binding on semiconductors

Scientists have succeeded in electrochemically detecting protein binding on semiconductor materials for the first time, thanks to a newly developed investigative method based on differences in electrical charge. Now the physicists are working on an optical process to detect and localize protein binding directly under a microscope, for example, a method that could launch new applications in medical research and diagnostics.
