UW Bioengineering assistant professor Dr. Daniel Ratner has developed a paper-based diagnostic system which uses plain paper. When treated with a divinyl sulfone and water solution, the paper becomes sticky to materials that could be of medical interest. The treated paper is run through a modified inkjet printer and printed with a biomolecule in an invisible pattern, and the pattern is revealed when a toxin is present. This proof of concept will be now used to develop actual diagnostic tests.
