摘要：

Increasing reaction temperature produces photoluminescent polymer nanodots (PPNDs) with decreased particle size and increased quantum yield. Such PPNDs are used as an effective fluorescent sensing platform for label-free sensitive and selective detection of Cu(II) ions with a detection limit as low as 1 nM. This method is successfully applied to determine Cu 2+ in real water samples. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
