FLASH! Paper-based Microfluidics

The Whitesides group at Harvard have hit on yet another great idea.  By preimpregnating paper with photoresist, a simple means of preparing paper-based microfluidics has been created.  They call it “FLASH” for Fast Lithographic Activation of Sheets.  Paper-based microfluidics devices for electrochemical sensing have been prepared by the group using similar techniques.
