A simple method that generates a forest of silver dendrites on aluminum foil turns out to be ideal for creating material to use as a substrate in surface-enhanced Raman spectroscopy, or SERS (J. Am. Chem. Soc., DOI: 10.1021/ja909806t). Since the 1970s, scientists have used metal surfaces to amplify the normally weak signals generated during Raman spectroscopy. Although the mechanism . . .
