The nano-scaffold, made of short peptides, is biodegradable and non-toxic, causes no immune response, is injectable -- it self-assembles when the molecules come together in a salty solution -- and, because it is composed of nanofibers, allows an intimate interaction between the peptide matrix and the surrounding tissue. The researchers say that it provides a 'permissive environment' that helps cells, such as neurons, regrow and knit together damaged tissue."
