Diagnostics In The Palm Of Your Hand

Electrochemiluminescence: A camera phone quantitatively captures signals
Department: Science & Technology, Government & Policy
Keywords: Paper, diagnostic, camera phone, electrochemiluminescence, NADH

A sheet of paper and a mobile phone together could create a cheap, portable alternative to typical laboratory-based and expensive diagnostic techniques. Researchers in Australia have created a simple medical device that generates signals based on electrochemiluminescence (ECL) that camera phones can capture (Anal. Chem., DOI: 10.1021/ac102392t).

Colorimetry and electrochemistry are already standard ways to detect molecules in paper devices. But analytical chemist Conor . . .
