Abstract

The increasing development of biomedicine and bioelectronics has highlighted the requirement for smart materials that can respond to changes in physical and chemical properties under external environments, such as magnetic fields, electric fields, and temperature. Accordingly, hydrogels have been widely evaluated as promising candidates for smart materials owing to their intriguing structures comprising a cross-linked network of polymer chains with interstitial spaces filled with solvent water. This feature endows hydrogels with soft and wet characteristics, which not only induce high tissue affinity but also allow the introduction of environmentally responsive nanoparticles to release specific smart properties. Herein, we reviewed novel smart hydrogels that can be applied in biomedicine and bioelectronics, and highlighted and discussed existing challenges in current technologies and research.

生物医学和生物电子学领域智能水凝胶研究进展
随着生物医学和生物电子学的不断发展,对能够响应外部环境(如磁场、电场和温度)下物理和化学性质变化的智能材料的需求日益突出。因此,水凝胶被广泛评价为智能材料的有前途的候选者,因为它们的有趣结构包括一个交联的聚合物链网络,间隙充满了溶剂水。这一特性赋予了水凝胶柔软湿润的特性,这不仅可以诱导高组织亲和力,还可以引入对环境敏感的纳米颗粒来释放特定的智能特性。本文综述了可用于生物医学和生物电子学的新型智能水凝胶,并重点讨论了当前技术和研究中存在的挑战。
