Hydrogels are water-swollen three-dimensional networks made of polymers, proteins, small molecules or colloids. They constitute a versatile platform for drug delivery because of their capacity to encapsulate and protect drugs and provide sustained and/or remotely programmable spatial and temporal release and have thus generated a substantial amount of research for the delivery of either small active compounds or biopharmaceuticals. This article discusses the features that make hydrogels attractive as matrices for delivery and reviews a range of designs, focussing on studies from recent years, in particular: ‘smart’ hydrogels (responding to temperature, light, magnetic fields, ultrasounds or combined stimuli); recent technologies: 3D printing and microneedles; and closes by discussing polymer-free drug delivery systems: peptides, small molecules and colloids.

用于药物输送的水凝胶设计策略

水凝胶是由聚合物,蛋白质,小分子或胶体制成的水溶胀的三维网络。它们具有封装和保护药物的能力,并提供持续和/或可远程编程的空间和时间释放,因此构成了用于药物输送的通用平台,因此已经为输送小型活性化合物或生物药物进行了大量研究。本文讨论了使水凝胶作为传递基质具有吸引力的特性,并回顾了一系列设计,重点是近年来的研究,尤其是:“智能”水凝胶(响应温度,光,磁场,超声或组合刺激);最新技术:3D打印和微针;最后讨论无聚合物的药物输送系统:肽,
