A new rhodamine-based fluorescence probe (AG-RB) is reported. This probe exhibits favorable cell-permeable due to the introduction of d-glucosamine and has been successfully used to detect intracellular Hg 2+ by fluorescence imaging method. The modified-rhodamine chitosan material (CS-RB) is able to recognize and adsorb Hg 2+ by spectroscopic and “naked-eye” method in water.
A novel hybrid material (SBA-P1) is prepared through the functionalization of mesoporous silica (SBA-15) with a 1,8-naphthalimide-based dye by sol–gel reaction. The characterization results of elemental analysis (EA), X-ray powder diffractometer (XRD) and spectroscopic methods demonstrate the fluorescence dye P1 is successfully grafted onto the inner surface of SBA-15 and the organized structure is...
