<p>A novel aqueous lubricant technology designed to help people who suffer from a dry mouth is between four and five times more effective than existing commercially available products, according to laboratory tests. </p>
<p>Developed by scientists at the University of Leeds, the saliva substitute is described as comparable to natural saliva in the way it hydrates the mouth and acts as a lubricant when food is chewed. </p>
<p>Under a powerful microscope, the molecules in the substance - known as a microgel - appear as a lattice-like network or sponge which bind onto the surface of the mouth. Surrounding the microgel is a polysaccharide-based hydrogel which traps water. This dual function will keep the mouth feeling hydrated for longer. </p>
<p>Professor Anwesha Sarkar, who has led the development of the saliva substitute, said: “Our laboratory benchmarking reveals that this substance will have a
