Stabilising hydrogels using dipeptides

在我的项目中，三个二肽（一种含有两个氨基酸残基的分子）在非常低的浓度（1mm）被用来稳定水泡沫和乳液。通过将二肽分散在碱性溶液中，可以通过添加适当的盐形成水凝胶。这些水凝胶既可以充气形成泡沫，也可以用不同的油乳化。通过改变色散相的物理化学条件，我们研究了如何在很长一段时间内稳定这些系统。

For my project three dipeptides (a molecule containing two amino-acid residues) at a very low concentration (1 mM) are used to stabilise aqueous foams and emulsions. By dispersing the dipeptide in a basic solution, hydrogels can be formed via addition of an appropriate salt. These hydrogels can then be either aerated to form a foam, or emulsified by using different oils. By changing the physicochemical conditions of the dispersion phase, we study how to stabilise these systems for long periods of time.
