controlling the gelation process. However, our experimental investigation reveals that hydrogelator II, containing Tyr as the aromatic core, shows an excellent gelation ability. But the Trp analogue fails to do so under similar conditions. To validate our results we performed MD simulation in an aqueous environment which significantly justifies that hydrogelator II exhibits a better hydrogelation ability
受生物启发的自组装肽是制造具有定制功能的纳米材料的有力基础。受萘基-Phe-OH(水凝胶化剂I)的超胶凝能力的启发,我们合成了萘基-Tyr-OH(水凝胶化剂II)和萘基-Trp-OH(水凝胶化剂III),目的是探索Tyr酚羟基的倾向。和吲哚的NH用于控制胶凝过程。但是,我们的实验研究表明,水凝剂II含有Tyr作为芳族核的凝胶显示出优异的胶凝能力。但是,Trp类似物在类似条件下无法做到这一点。为了验证我们的结果,我们在水性环境中进行了MD模拟,这充分证明了水凝剂II具有比水凝剂I和III更好的水凝能力。然后使用各种分析和显微镜技术对水凝胶剂II进行详细的表征,并使用MTT分析法测试其生物相容性。为了检查水凝胶的潜力II在药物递送我们使用的概念开发水凝胶的纳米颗粒(的HNP)自组装完全由生态友好的途径支配即弱相互作用(如氢键,π–π和疏水相互作用)。我们的水凝胶纳米颗粒根据其化学结构,分子量和
