Abstract

An ultrasensitive surface-enhanced Raman scattering (SERS) substrate with large area uniform subnanometer “hot spots” is used to detect mercuric ions in water and sandy soil, by Hongbing Deng, Fubing Wang, Xiangheng Xiao, and co-workers in article number 1603347. The detection limit is as low as 8.3 × 10−9 m. The uniformity of the SERS substrate is proved by Raman mapping, and the physical mechanism of SERS enhancements is supported by the finite difference time domain method.
