Stimuli-responsive low molecular weight hydrogel interventions for Biomedical challenges are a rapidly evolving paradigm in the bottom-up approach recently. Peptide-based self-assembled nano biomaterials present safer alternatives to their non-degradable counterparts as demanded for today's most urged clinical needs.Although a plethora of work has already been accomplished, programming hydrogelators with appropriate functionalities requires a better understanding as the impact of the macromolecular structure of the peptides and subsequently, their self-assembled nanostructures remain unidentified. Henceforth this review focuses on two aspects: Firstly, the underlying guidelines for building biomimetic strategies to tailor scaffolds leading to hydrogelation along with the role of non-covalent interactions that are the key components of various self-assembly processes. In the second section, it is aimed to bring together the recent achievements with designer assembly concerning their self-aggregation behaviour and applications mainly in the biomedical arena like drug delivery carrier design, antimicrobial, anti-inflammatory as well as wound healing materials. Furthermore, it is anticipated that this article will provide a conceptual demonstration of the different approaches taken towards the construction of these task-specific designer hydrogels. Finally, a collective effort among the material scientists is required to pave the path for the entrance of these intelligent materials into medicine from bench to bedside.
刺激响应型低分子量水凝胶干预物是近年来从下至上方法中快速发展的范例。基于肽的自组装纳米生物材料作为当今最迫切的临床需求的替代物,提供了更安全的选择,因为它们是非可降解的。尽管已经完成了大量的工作,但要对水凝胶剂进行适当的功能编程,需要更好地了解肽的高分子结构及其随后的自组装纳米结构的影响仍然未知。因此,本综述重点关注两个方面:首先,构建仿生策略以定制支架的基本指导原则,从而导致水凝胶化,以及非共价相互作用的作用,这是非凡自组装过程的关键组成部分。在第二节中,旨在汇集与设计师组装有关的最新成就,涉及它们的自组装行为及其在生物医学领域的应用,如药物输送载体设计、抗菌、抗炎以及伤口愈合材料。此外,预计本文将为构建这些特定任务的设计水凝胶的不同方法提供概念性演示。最后,需要材料科学家们共同努力,为这些智能材料从实验室到临床进入医学铺平道路。
