From the author: Contamination of the environment with pathogens and heavy metal ions can have adverse effect on human health and environment. Since world population is expected to be 8 billion by 2025, it is impossible to improve living standards without affecting the environment. Due to contaminations by toxic metals, about half a billion people around the world face shortages of drinking water of good quality. To detect low concentration of such contamination, scientists need to develop sensors for real-time detection of toxic metals and pathogen in water supplies for ensuring the safety of municipal and recreational water supplies. Nanomaterial based method can have advantages compared to conventional methods in terms of the time of analysis, selectivity and sensitivity. This review discusses our and other group recent effort on the development of gold nanomaterials based probe to detect mercury from environmental sample with excellent selectivity and sensitivity and which can improve the analytical figures of merit, such as detection limits, sensitivity, selectivity, and dynamic range, relative to the commercial systems.
