Colorimetric sensing for the sensitive detection of UO₂²⁺via the phosphorylation functionalized mesoporous silica-based controlled release system

Abstract

In this study, we developed a simple and sensitive colorimetric sensing method for the detection of UO22+, which was built to release MB from the molybdenum disulfide with a phosphate group MoS2-PO4) gated mesoporous silica nanoparticles functionalized phosphate group (MSN-PO4) with UO22+ chelating.
