Chitosan (CHT) is a known piezoelectric biomacromolecule; however, its usage limited due to rapid degradation in an aqueous system. Herein, we prepared CHT film via solvent casting method and cross-linked alkaline solution. Sodium hydroxide facilitated deprotonation, leading increased intramolecular hydrogen bonding mechanical properties. The remained intact for 30 days environments. A systematic study revealed gradual increase the output voltage from 0.9 1.8 V under external force (1-16 N). In addition, showed remarkable antibacterial anti-inflammatory activities ultrasound stimulation inhibition of inflammatory cytokines. films also displayed enhanced cellular proliferation ∼5-fold faster migration NIH3T3 cells US stimulation. Overall, this work presents robust, biocompatible, wearable device that can transform biomechanical energy into electrical pulses modulation cell fate processes other bioactivities.

Herein, we first report an eco-friendly and easily retrievable piezo-responsive membrane fabricated by encapsulating chemically synthesized cobalt chromate quantum dots (CCOQDs) at varying concentrations (0%, 10%, 20%) in poly(vinylidene fluoride) (PVDF) using a facile solution-casting method. The with 10% CCOQDs (PCCO 10) exhibited high β-phase fraction (75.93%), significant dielectric constant (56.22) notable piezo-coefficient (d33= 65.1 pC/N), demonstrating strong piezocatalytic activity. It effectively generated reactive oxygen species (ROS), which reacted dye solutions, leading to 98.7% congo red (CR), 89.9% methylene blue (MB), 87% mixed (1:1 of CR MB) degradation within 50 min soft ultrasonic stimulation, primarily due •OH radicals, as confirmed scavenger trapping experiments. Additionally, the removed 81.98% total organic carbon (TOC) 75 min. Optimization alkaline pH solution, 60 W power, 1 ppm concentration enhanced its catalytic efficiency, selectivity, stability. Real-world testing on drinking wastewater showed efficiencies 94.65% 98.31%, highlighting versatility for industrial household applications. flexible PCCO 10 also demonstrated excellent reusability (97.2% efficiency after four cycles) maintained structural integrity under low-frequency such centrifugation, vortexing, stirring, confirming activity degradation. Furthermore, products were identified LC-MS technique. Also, pot study established that these molecules have no phytotoxic effects neem (Azadirachta indica) plants. Hence, this multifunctional free-standing holds promising potential alternative sustainable treatment.
