Evidence Details
ZnO NPs were prepared via microwave synthesis. ZnCl2 (0.15 g) and Na2CO3 (10 g) were dispersed in deionized water (50 g) and stirred for 30 min at room temperature. The solution was then placed in a microwave synthesizer (800 W, XH-MC-1, Beijing Xianghu Technology Development Co., LTD, China), reacted for 10 min at 60, 70, 80, and 90°C, respectively, cooled...
Additional source evidence: source values include 808 nm, 1.0 W, 3 min, 11.1°C. Entities: ZnO-80.
ZnO NPs (5 wt.%) with a spindle morphology and photothermal activity were synthesized and incorporated into a chitosan/gelatin (1:1) blend, acting as light-to-heat converters. When exposed to light, these ZnO NPs induced a localized temperature increase of 10.3 to 14.2°C. This rise in temperature facilitated the movement of polymer chains, triggering a rever...
After 20 minutes of light exposure, the antimicrobial rate of CS/G/ZnO/PHMG against E. coli and S. aureus reached 97.3% and 99.4%, respectively, and remained stable thereafter.
Additional source evidence: source values include 9.1°C, 5.9°C, 4.1°C. Entities: ZnO-60, ZnO-70, ZnO-90.
Additional source evidence: source values include 1%, 50°C, 30 min.
Additional source evidence: source values include 1%, 50°C, 1 h.
Release evidence: source values include 386%, 97.3%, 99.4%.
Unlike traditional approaches that rely on the ROS antibacterial properties of ZnO NPs, this study utilizes the photothermal effect to develop a light-responsive antibacterial coating. This strategy avoids the potential health risks associated with small-sized ZnO NPs (< 100 nm).
Additional source evidence: source values include 42.4 ± 11.2 nm, 195.9 ± 58.1 nm. Entities: ZnO-80.
Additional source evidence: source values include 20 min, 97.3%.
Additional source evidence: source values include 25.8%, 29.5%.
Additional source evidence: source values include 12 h, 24 h.
