Scientists have created a microgel that can replace human saliva | November 21, 2023

Scientists from the University of Leeds have created a microgel whose properties are comparable to natural saliva: it moisturizes the oral cavity and acts as a lubricant when chewing food. About it writes Daily Mail.

Under a microscope, the molecules of the substance appear as a latticework or sponge that attaches to the surface of the mouth. The microgel is surrounded by a polysaccharide-based hydrogel capable of retaining water. Both components of the saliva substitute will keep your mouth feeling moist longer.

The microgel comes in two forms: milk protein based and a vegan version using potato protein. The substances used in the production of saliva substitute, that is, milk and vegetable proteins and carbohydrates, are non-toxic to humans and non-caloric.

The authors of the development intend to introduce microgel into food products to improve the quality of life of people experiencing debilitating dry mouth.

Previously, Russian scientists created artificial cornea.
