IDA-based Differential Sensory Arrays and Assays

Abstract

For the pattern-based recognition of various metal species and bioanalytes, nature has stimulated an emergent supramolecular domain of synthetic receptor arrays and assays. It is not always necessary for a synthetic receptor to be selective for a particular analyte in a differential receptor array, but the inclusive signal response from a typical sensory array must be diagnostic for the target analyte. This new category of molecular recognition is rapidly advancing with various groups constructing novel array platforms as well as receptors. Owing to easy operation and better selectivity, the sensory array has gained significant attention in the realm of complex system analysis. Besides the conceptual background, the authors have elaborated on the applications of various differential arrays through numerous examples. The authors believe that this chapter devoted to IDA-based differential sensory arrays and assays will bring a new episode of IDA-based chemosensors for target analytes.
