Aruna, Neelam Sharma, Suman Swami, Ritu Mathur, Rashmy Nair and Rahul Shrivastava

Abstract

Fluorescent nanosensors are capable of sensitive and selectively sensing target heavy metal ions under physiological conditions. In recent years, these sensors have attracted enormous interest as they offer outstanding features such as high selectivity, simplicity, extraordinary sensitivity, simple manipulations, rapid response rate, low cost, facile visualization real-time detection, and spatiotemporal resolution. Generally, fluorescent chemosensors exhibit significant noticeable changes in their physicochemical properties upon interaction with target guest analytes and generate detectable fluorescent signal. In the previous times, a wide range of fluorescent nano-chemosensors with sensing capabilities have been designed and evaluated for sensing purposes. Coumarins are a family of 2H-chromen-2-one scaffold, generally found in plants in nature. In recent years, coumarin scaffold has been extensively utilized in designing of fluorescent chemosensors because of its high fluorescence quantum yield, stable and strong fluorescence emission, excellent biocompatibility, low toxicity, and good structural flexibility. This review article emphasis on decennary development of coumarin derived fluorescent and nano-chemosensors for metal ions sensing during the time of 2013 – 2022. This piece of review article could facilitate the scientific community for the advancement of more efficient fluorescent chemosensors and nano-chemosensors for exciting wide range applications in the future.
