Fluorescent chitosan-BODIPY macromolecular chemosensors for detection and removal of Hg2+ and Fe3+ ions

On the Use of Polymer-Based Composites for the Creation of Optical Sensors: A Review

“…Materials obtained by covalent binding are used to increase the effectiveness of photodynamic therapy (by covalent bonding of BODIPY through hydroxyl group to DND/Pc hybrid) [ 74 ], in block materials with AIE effect [ 75 ], solar cells [ 76 , 77 ], FET devices [ 78 ], material for sensing and removal Hg 2+ and Fe 3+ (was synthesized by click reaction between NH 2 /C≡C (chitosan(CS)/dye)) [ 79 ], sensors for guanine and adenine in PBS (SWCNT matrix) [ 80 ], pH and thermo responsive nano probe (rGO matrix) [ 81 ], CO 2 adsorption (by preparing porous luminescent polymer) [ 82 ], self-healing gels [ 83 ], wastewater treatment [ 84 ].…”

TEGylated Phenothiazine-Imine-Chitosan Materials as a Promising Framework for Mercury Recovery

“…In line with this requirement, eco-materials based on biopolymers, able to detect and recover heavy metals, constituted the base of new materials designed to detect or recover mercury. Cellulose-, lignin-, chitosan-, or peptide-based hydrogels/xerogels proved to have a high ability to bond mercury, encouraging their deeper consideration, in order to create high-performance adsorbent materials [ 23 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. It was established that polysaccharides are excellent sorbents for heavy metals thanks to their ability to develop physical and electrostatic forces, which can be further improved by grafting moieties capable of coordinating metals.…”

Synthesis, “turn-on” fluorescence signals towards Zn2+ and Hg2+ and monoamine oxidase A inhibitory activity using a molecular docking approach of morpholine analogue Schiff base linked organosilanes

“…16 Even small concentrations can cause serious damage to the heart, brain, kidney and central nervous system. 17,18 Hence, reliable and sensitive detection of Zn 2+ and Hg 2+ is critical. To date, fluorescence-based probes have been chosen as the best detector for Zn 2+ and Hg 2+ due to their low cost, quick response and high sensitivity.…”
