Nature has developed excellent biolubricating systems but onnce biolubrication for instance of synovial joints of osteoarthritis patients breaks down, relief has to come from partially or fully synthetic biolubricants - such as polymeric micro- or nanoparticle-based lubricants - that replace the depleted natural substances. Researchers have now demonstrated that phytoglycogen nanoparticles - single-molecule highly branched polysaccharides extracted from sweet corn kernels - are a highly ...
