From: Retrievable hydrogel networks with confined microalgae for efficient antibiotic degradation and enhanced stress tolerance

Fig. 4

a–c Fluorescence images depicting the distribution of live and dead CZ cells in SM (a), MHN (b), and MHN@TA (c) systems before and after incubation in 400 mg L−1 TC. Red indicates live cells and green indicates dead cells. d, e Relative Chl content of microalgae in SM (d), and MHN@TA (e) systems under different TC concentrations. Each experimental group consisted of three biological replicates. f Changes of Fv/Fm in SM, MHN, and MHN@TA systems under different TC concentrations. Each experimental group consisted of four biological replicates. g Diffusion dynamics simulation in SM and MHN@TA systems. h Photo of a free-standing and flexible MHN@TA fencing system (70 cm × 40 cm × 0.5 cm). i Photo of wastewater sampled from a contaminated pond in Sichuan, China. j Removal efficiency of MHN@TA system for simulated antibiotic-containing wastewater. Each experimental group consisted of three biological replicates. k Comparison of the degradation performance of MHN@TA with other reported methods. Data were presented as the mean ± s.d. (n = 3). Source data are provided as a Source Data file.
