Analytical chemistry: Sense and versatility
A. Prasanna de Silva1
Abstract
Molecules that detect chemicals are the workhorses of analytical devices, but most recognize only one kind of target. A molecular sensor has now been devised that measures the concentrations of several metal ions.
What do the following things have in common: industrial effluents in a lake, signalling pathways in a cell and the blood status of a patient? The answer is that they can all be monitored by studying the concentrations of metal ions.
