摘要：
Arsenic ion is a well-known harmful heavy element widely existing in the environment. Arsenic pollution occurring frequently has become increasing a serious worldwide threat to human health and the environment. The development of sensitive and reliable methods to detect As3+ in water is of great importance to biochemical research and monitoring applications. Herein, a label-free fluorescence sensing platform was elaborately designed for As3+ monitoring using exonuclease III (Exo III)-assisted cascade target recycling amplification strategy. The triple-helix molecular switch was employed as the...
