A multi-pH-dependent, single optical mesosensor/captor design for toxic metals.

The fabrication of low-cost, simple nanodesigns with sensing/capture functionality has been called into question by the toxicity and non-degradability of toxic metals, as well as the persistent threat they pose to human lives. In this study, a single, pH-dependent, mesocaptor/sensor was developed for the optical and selective removal of toxic ions from drinking water and physiological systems such as blood.
