Intelligent wearable sensors play a crucial role in the detection of toxic gases and monitoring physiological signals, thereby effectively ensuring environmental and personal health safety. Nonetheless, achieving the requirements for antibacterial properties, comfortable wear, and multifunctional detection remains a major challenge. In this study, a novel Def‐ZIF‐8/PPY/BC‐based flexible sensor is developed by in situ growth of zeolitic imidazolate frameworks‐8 (ZIF‐8) and polypyrrole (PPY) on bacterial cellulose (BC), followed by water immersion. The Def‐ZIF‐8/PPY/BC‐based flexible sensor demonstrates effective dual‐sensitivity responses to nitrogen dioxide (NO2) toxic gas and stress‐strain behaviors at room temperature. The structural characterization and theoretical calculations affirm that the innovative water treatment method successfully introduces defects into ZIF‐8, resulting in a significant 2.57‐fold improvement in response intensity to 80 ppm NO2. Stress‐strain sensing performance analysis reveals that the Def‐ZIF‐8/PPY/BC‐based flexible sensor exhibited high sensitivity (6.44 kPa−1), rapid response and recovery times (0.7/0.4 s), and exceptional cyclic stability (8000 cycles). Further, the inhibitory effect of ZIF‐8 on common bacterial strains contributes to the exceptional antibacterial properties (antibacterial rate exceeding 99%) of the Def‐ZIF‐8/PPY/BC based on the flexible sensor. This study offers a significant advancement in metal‐organic framework defect engineering and provides an effective strategy for developing multifunctional wearable sensors.

“…According to their results, the Pb 2+ and Cu 2+ removal occurred through the adsorption mechanism and ion-exchange phenomenon, respectively. ZIF-8 is one of the most stable structures among MOF materials in aqueous solutions, which can be prepared through different synthesis routes, such as solvo-hydro thermals [14,15], microwave-assisted [16], sonochemical [17], mechanochemical [18], dry-gel [19], and microfluidic [20]. Among them, the solvo-hydro thermal methods are preferred due to the good yields and purity of the produced ZIFs.…”

A Zeolitic imidazolate framework-8 (ZIF-8) was synthesized by the solvothermal method of zinc nitrate hexahydrate and 2-methylimidazole in DMF to remove Cd(II), Ni(II), and Pb(II) ions from aqueous solutions. The synthesized ZIF-8 was distinguished by XRD, FT-IR, BET, SEM, EDX, TEM methods. Several significant variables were optimized with response surface methodology (RSM) to obtain the highest removal of metal ions. According to the achieved results, the aqueous solution pH values of 6.5, 6.5, and 6.0, ZIF-8 dosages of 0.05, 0.06, and 0.05 g⸳L-1, and metal ions initial concentrations of 50, 60, and 60 mg⸳L-1 were chosen as the optimum amount of these variables for Cd(II), Ni(II), and Pb(II) ions adsorption from solution, respectively. The equilibrium time for metal ions adsorption was found at 50 min. Three-dimensional plots demonstrate relationships between the metal ion uptakes with the paired factors, which illustrate the behavior of the sorption system in a batch process. Based on the experimental results and model parameters, maximum adsorption efficiencies were achieved 89.76, 72 and 68.43% for Cd(II), Ni(II) and Pb(II), respectively. It can be suggested that the synthetized ZIF-8 has excellent potential as an effective adsorbent and used for heavy metal sorption from water environment.
