Surface-bound anion sensors

Many aspects of anion recognition by metal-based receptors have been covered in previous reviews [1-5]. This review is not intended to be comprehensive rather, it provides an overview of the subject with particular reference to the specific properties that metal-containing sub-units impart to this class of anion sensor. The most recent advances in the field are also detailed including the use of metallo-receptors in dendrimer, functionalised nanoparticle and surface-bound anion sensors.
