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

In this study, we developed a simple and sensitive colorimetric sensing method for the detection of UO 2 2+ , which was built to release MB from the molybdenum disulfide with a phosphate group MoS 2 -PO 4 ) gated mesoporous silica nanoparticles functionalized phosphate group (MSN-PO 4 ) with UO 2 2+ chelating.
