Tetracycline (TC), a widely used antibiotic, poses environmental persistence and contributes substantially to the formation of drug-resistant bacteria, warranting urgent actions for effective detection and degradation. Recent progress in micro/nanomotor technology has opened a compelling avenue, enabling active maneuverability in aqueous environments while improving interaction efficacy and functionality. In this study, a succulent-like ZnO/metal-organic framework (MOF)/Fe3O4hybrid micromotor designed for dynamic fluorescence detection and efficient photocatalytic degradation of TC is proposed. By leveraging micro- and nano-fabrication approaches and the seeded growth method, the fabrication of ZnO micromotors with succulent-like structures is realized. Notably, chemical modifications are employed to manipulate the surface potential and precisely control the motion direction of the micromotor. Further incorporation of fluorescent MOF nanoparticles renders the micromotors capable of dynamic TC detection. Furthermore, under ultraviolet irradiation, the micromotors exhibit dynamic TC degradation and can be conveniently recovered and reused by magnetic separation. The rational design of functional micromotors may offer promising platforms for various applications such as dynamic detection and environmental remediation.

The all-day passive radiative cooler has emerged as one of the state-of-the-art energy-saving cooling tool kits but routinely suffers from limited processability, high cost, and complicated fabrication processes, which impede large-scale applications. To address these challenges, this work exploits a polymer-based passive radiative cooler with optimized turbidity, reconfigurability, and recyclability. These cooling membranes are fabricated viaselective condensation of octyl side chain-modified polyvinyl alcohol through a non-solvent-induced phase separation method. The rational tuning over spatial organization and distribution of the air–polymer interface renders optimized bright whiteness with solar reflectance at 96%. Meanwhile, the abundant −C–O–C– bonds endow such membranes with infrared thermal emittance over 90%. The optimized membrane realizes a subambient cooling of ∼5.7 °C with an average cooling power of ∼81 W m–2under a solar intensity of ∼528 W m–2. Furthermore, the supramolecule nature of the developed passive radiative cooling membrane bears enhanced shape malleability and recyclability, substantially enhancing its conformability to the complex geometry and extending its life for an eco-friendly society.
