Abstract

Sensors play an important role in detection of various cation, anions and neutral molecules in chemical and biological samples and have found much interest in the three decades. The sensors bind with analyte species, which lead to change in electron density on sensor molecules and cause changes in its signals or color. Varieties of chemical sensors are used including cationic and anionic and neutral molecules sensors. Molecular recognition and molecular transduction take place in chemical sensing. Generally, a chemosensors consist of three parts, receptor which is binding site, unit whose properties change with binding and spacer.
