Fluorogen-Functionalized Mesoporous Silica Hybrid Sensing Materials: Applications in Cu2+ Detection

Abstract

Since Cu²⁺ ions play a pivotal role in both ecosystems and human health, the development of a rapid and sensitive method for Cu²⁺ detection holds significant importance. Fluorescent mesoporous silica materials (FMSMs) have garnered considerable attention in the realm of chemical sensing, biosensing, and bioimaging due to their distinctive structure and easily functionalized surfaces. As a result, numerous Cu²⁺ sensors based on FMSMs have been devised and extensively applied in environmental and biological Cu²⁺ detection over the past few decades. This review centers on the recent advancements in the methodologies for preparing FMSMs, the mechanisms underlying sensing, and the applications of FMSMs-based sensors for Cu²⁺ detection. Lastly, we present and elucidate pertinent perspectives concerning FMSMs-based Cu²⁺ sensors.
