具有生物力学和生化活性的敷料在伤口护理和皮肤组织再生中起着至关重要的作用.然而,机械失配和药物释放管理所涉及的问题限制了当前敷料的有效使用.在本工作中,我们报道了一种简单的策略,即采用聚偏二氟乙烯(PVDF)作为底物,通过嵌入不同尺寸的沸石咪唑酸盐框架(ZIF-8)种子,以推动具有均匀蜂窝结构的高柔性金属有机框架(MOF)复合膜的受控生长,用于药物负载和释放.以嵌入的种子为控制中心,形成的多孔膜具有约0.7-3μm的宽孔隙.这种可调节的微尺度孔与ZIF-8中的固有纳米孔不仅可以有效地提高抗炎类药物的负载(姜黄素,CCM),而且还能够快速并可控地释放药物,大大提高了抗菌活性,同时促进细胞生长.其中,在40 nm种子上生长的0.7μm多孔膜的表现优于其他蜂窝膜,与2μm多孔膜(相当于裸PVDF基质)相比,细胞增殖能力提高了约2倍,针对金黄色葡萄球菌(***)和大肠杆菌(***)的抗菌活性分别提高了5倍和2.4倍,是基底抗菌活性的5倍,这是因为这种最佳孔几何结构具有CCM和Zn2+释放特性的平衡效应.这种可控分层孔阵列膜的独特性质有望真正用于伤口愈合,同时也为生物医学设计提供了新的指导.

校园安全与学生校内违纪问题近年来关注热度逐渐上升,随着数智时代的到来,应对和防范学生违纪问题的措施越来越多,当前广泛使用的视频监控和校园一卡通等相关技术有一定的局限性,无法有效地防范违纪问题的发生,因此,通过三种场景将物联网与可安装在校园内的传感器连接起来,及时收集和处理数据,实现低能耗、广覆盖、低成本的数据处理并将数据上传到云端,通过MapReduce在云端进行数据处理,根据不同的违纪行为产生预警,使大数据技术与校园霸凌、旷课、吸烟等违纪识别相结合,为学校工作人员监控学生记录和安全问题提供有价值的信息。
