nanoscale fibers BALTIMORE, Maryland- medical engineers have long used as robust scaffolds for growing tissue . Now researchers develop nanofiber mesh that could suck insects on wounds and accelerate healing, they reported here this week at the 61st annual meeting of AVS. The scientists injected nanofibers bearing cells in wounds to stimulate tissue repair, but to design a really smart dressing, they need to know how matter interacts with bacteria. After testing nanofibres of different sizes, the researchers found that the bugs transfer most easily nanofibers with diameters corresponding to the sizes of bacteria. When scientists nanofibers placed in a Petri dish Staphylococcus aureus , a bacterium involved in chronic infection, insects were quickly attached to the fibers 500 nanometer wide (as seen below above), but only on the fibers with larger diameters. When the researchers coated nanofibers with different compounds and test them on bacteria Escherichia coli , also responsible for chronic wounds, insects form bridges on the coated fibers allylamine, a colorless organic compound, but stayed away from fibers coated with acrylic acid. The researchers, who plan to test the stitches on composites that resemble human skin, hoping that they will eventually lead to smart dressing the wound that could prevent infection. Doctors could stick the nano-Band-Aid on a wound and simply remove it to get rid of germs.
