Hydrophilic agent
Web1. Introduction. Nanomaterials can enable the controlled release of drugs and improve the stability of those agents, making a new way to disease treatment (Lang et al., Citation 2024).Hydrogels are three-dimensional networks of polymers containing hydrophilic groups which are cross-linked by covalent bonds, hydrogen bonds, van der Waals forces or … WebThe arrangement of the hydrophilic head is at the interface of water and the hydrophobic groups aligns toward oil. Therefore, a surfactant contains both a water-insoluble (or oil-soluble) component and a water-soluble component.
