摘要:

传感技术是健康与环境监测的基石,但其发展受限于传统界面材料的生物相容性与机械匹配性。水凝胶作为一类亲水性三维网络软材料,凭借其仿生特性和可调物化性质,为解决该瓶颈提供了理想平台。首次系统提炼并阐述了八大设计范式,包括功能核酸编程、酶催化与生物分子识别、合成超分子模块、纳米复合材料、物理限域效应、刺激响应聚合物、微针传感以及柔性可穿戴器件集成,明确了水凝胶在不同策略中作为主动响应单元或被动优化介质的核心角色。旨在为相关研究提供系统的理性设计框架,推动该领域从经验探索向理性构建的范式转变。

Abstract:

Sensing technology serves as a cornerstone for health and environmental monitoring, yet its advancement is constrained by the inadequate biocompatibility and mechanical compatibility of traditional interface materials. Hydrogels, as a class of hydrophilic three-dimensional network soft materials, offer an ideal platform to address this bottleneck owing to their biomimetic features and tunable physicochemical properties. For the first time, this review systematically summarized and elaborated on eight rational design paradigms for hydrogel-based sensors, including functional nucleic acid programming, enzymatic catalysis and biomolecular recognition, synthetic supramolecular modules, nanocomposite integration, physical confinement effects, stimulus-responsive polymer systems, microneedle-based sensing, and flexible wearable device integration. These paradigms clarified the central role of hydrogels as either active responsive units or passive optimization matrices across different strategies. The work aims to provide a systematic rational design framework for relevant research, facilitating a paradigm shift in the field from empirical exploration toward rational construction.

Key words: hydrogel, sensor, detection, rational design
