Abstract Nanozymes hold great promise for biosensing applications, yet their practical implementation is hampered by limitations in signal enhancement, reusability, and device integration. Herein, the development of a hydrophilic shape‐memory nanozyme aerogel that addresses these challenges reported. The platform constructed embedding chitosan‐protected platinum nanoparticles (Pt‐CS NPs), which exhibit intrinsic peroxidase (POD) activity, within polyacrylic acid (PAA) matrix. This hybrid Pt‐CS/PAA retains effect PAA component as well POD activity Pt‐CS NPs. Importantly, exhibits differential adsorption behaviors toward two distinct oxidation products, oxidized 3,3′,5,5′‐tetramethyl‐benzidine (oxTMB) 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (oxABTS), driven differing electrostatic potentials with aerogel. By integrating effect, catalysis, exceptional probe performance, enables realization signal‐amplified or reusable nanozyme‐based assay, when employing TMB ABTS chromogenic substrates, respectively. Furthermore, architecture allows straightforward deviceization, transforming analysis from conventional test paper formats into practical, sensing devices. work establishes generalizable blueprint engineering smart materials shape memory characteristics, opening up new avenues developing advanced platforms enhanced performance user‐friendly operability.

The recovery of valuable gold from wastewater is great interest because the widespread use precious metal in various fields and pollution generated by gold-containing wastes water. In this paper, a water-insoluble cross-linked adsorbent material (TE) based on cyanuric chloride (TCT) ethylenediamine (EDA) was designed used for adsorption Au(III) wastewater. It found that TE showed extremely high selectivity (D = 49,213.46) capacity (256.19 mg/g) under acidic conditions. rate remained above 90% eVen after five adsorption-desorption cycles. process followed pseudo-first-order kinetic model Freundlich isotherm model, suggesting physical with multilayer molecular overlay dominates. Meanwhile, mechanism obtained DFT calculation XPS analysis, mainly electrostatic interaction electron transfer between protonated N atoms AuCl
