“…[16c] Nanozymes can be used with target analytemediated redox processes to achieve detection of target analytes through signal conversion, and are therefore widely used in biosensing. [68] Porphyrin-based nanozymes have been used to detect CO 2 , [28] bacteria, [45] glucose, [44,51] heparin, [32] and other biological indicators of disease substances. Porphyrins have been utilized as fluorescent detectors due to their strong light absorption.…”

“…Nonplanar porphyrins are characterized by excellent catalytic activity, high stability, and adjustable axial binding strength. [ 28 ] A nonplanar porphyrin, 2,3,7,8,12,13,17,18‐(octaethyl)−5,10,15,20‐tetrakis(4‐carboxybiphenyl)porphyrin (OETPP), was used as the linker to synthesize a MOF nanozyme (PPF‐100) through the combination with Cu(NO 3 ) 2 ·2.5H 2 O ( Figure A). The nanozyme was formed by in situ metallization of OETPP and formation of a 2D mesh structure using Cu paddlewheel cluster as the building block (Figure 2B,C).…”
