Abstract

We propose a novel method for highly sensitive SERS detection of Cd2+ ions based on TMPyP-triggered Ag aggregates, which is achieved via a simple electrostatic interaction. In particular, this sensing system is relatively simple, but provides high sensitivity and excellent selectivity in a high-throughput fashion.
