摘要：

The detection of some metal ions has been investigated using an optical sensor based on surface plasmon resonance (SPR). A multilayer sensing chip was prepared with a dithiosquarylium (DTSQ) dye sensing layer coating on a gold layer. Using the DTSQ dye as a metal ion sensing molecule, a highly selective response for Ag+ was observed. (C) 2000 Elsevier Science Ltd. All rights reserved.
