✦ Synopsis

Sherif El-Safty and co-workers report on the synthesis of large-scale optical nanosensor arrays. In this work, sensitivity and fast-response detection of multiple toxic ions are retained despite the implementation short fabrication times and the use of low-cost materials. Highly accessible, flexible, finely tuned surface probes lead to pool-onsurface sensing systems in which high flux of the metal analytes across the indicator molecules is rapidly achieved. These sensing pools show promising sensitivity up to sub-picomolar recognition, long-term stability, reversibility, and selectivity for the detection of most pollutant cations.
