... 147 cells/ mm 2 for the negative control, 1681 cells/mm 2 for the positive control, and 1253 cells/mm 2 for the Sundew adhesive coated surface. Due to the non-uniformity i n the coating of the Sundew ... nanofiber and nanoparticle based nanocomposite from the adhesive of Sundew can be used for tissue engineering, and opens the possibility for fu...
