Scientists at the University of Washington have discovered a simple way to raise the accuracy of diagnostic tests for medicine and common assays for laboratory research. By adding polydopamine — a material that was first isolated from shellfish — to these tests at a key step, the team could increase the sensitivity of these common bioassays by as many as 100 to 1,000 times.

Three scientists at the University of Washington have proposed a way to speed up common bioassays used in research and diagnostics. Their solution, reminiscent of the magic behind washing machines, could reduce wait times to a fraction of what they once were. As they report in the journal Small, biological assays that once took hours could instead take minutes.
