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‐on‐surface 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.
