A novel enzyme-free long-lasting chemiluminescence system based on a luminol functionalized β-cyclodextrin hydrogel for sensitive detection of H2O2 in urine and cells

In this work, a biocompatible hydrogel with long-lasting chemiluminescence properties was synthesized using a simple method, and it was used as an enzyme-free biosensor interface and bioimaging probe for the detection of H 2 O 2 in urine and tumor cells.
