Colorimetric and Fluorimetric Chemosensors
for Detection of Anions, Cations, pH and Small
Molecules

Chemosensors are the tools that provide us with rapid and easy ways to understand and determine what happens in our environment. Colorimetric and fluorimetric changes are promising in real-world situations and applications. In particular, many chemosensors have been developed for sensing and imaging small molecules such as cations, anions, neutral species, and biologically important molecules (such as DNA and proteins) associated with human living systems, as well as therapeutic and diagnostic applications. In this thematic issue, various chemosensors have been covered in design and their applications.
