Abstract: The identification of heavy metals by sensing technologies is a crucial area of study since these metals are present in the environment and are
hazardous. The in-depth analyses of the probes' structures and sensing capabilities improve our understanding of how to design and develop probes
for the same metal in the future. The third most common metal ion and trace element, copper (Cu2+), is essential to all living things and is involved
in several activities. However, different diseases are caused by excess or deficiency of Cu2+ ions, depending on what the cell requires. For all of
these reasons, optical sensors have concentrated on quick, highly sensitive, and selective real-time detection of Cu2+ ions. Fluorescence in the
refractive index-adsorption from the interactions between light and matter can be measured using optical sensors. Furthermore, due to their strong
advantages which include real-time detection, simplicity and naked eye recognition, low cost, high specificity against analytes, quick reaction, and
the requirement for less complex equipment during analysis they have attracted a lot of attention in recent years. In this review, we covered many
fluoro and chemosensors for the detection of copper, along with their sensing parameters in various mediums and thorough structural analyses.
This review also covers the extraction of copper from the aqueous medium. The use of membrane processes, adsorption, and electrocoagulation is
examined, and the difficulties associated with their application have been presented.
