Self‐Assembly of Unprotected Dipeptides into Hydrogels: Water‐Channels Make the Difference

Unprotected dipeptides are attractive building blocks for environmentally friendly hydrogel biomaterials by virtue of their low‐cost and ease of preparation. This work investigates the self‐assembling behaviour of the distinct stereoisomers of Ile‐Phe and Phe‐Ile in phosphate buffered saline (PBS) to form hydrogels, using transmission electron microscopy (TEM), attenuated total reflectance infrared spectroscopy (ATR‐IR), circular dichroism (CD),...
