title: A visual volumetric hydrogel sensor enables quantitative and sensitive detection of copper ions.
abstract: We propose a visual volumetric sensor with 5,6-dicarboxylic fluorescein cross-linked amine-functionalized polyacrylamide hydrogel. The sensor undergoes volume response to Cu(2+) ions at the μM level, which enables naked-eye quantitative detection by reading the graduation on a pipette.
