This book has shown that research into drug engineering becomes an exciting activity, once fruitful feats have been achieved. This, is probably due to the majority of scientists, under pain, to find a hobby, accompanied by a responsible and tranquil mind. This modest manuscript will help you, in a reliable way, to capture the advances of science, at the level of galenic formulation, of dressings, for wounds and infected wounds, at the level of human skin. These exist in the form of a hydrogel or hemostatic dressing for local application. More specifically, we are interested in the design of antibacterial, anti-inflammatory and wound-healing bionanocomposites with optimal therapeutic effects and high long-term stability for benign skin diseases, which are thought to be responsible for superficial or even deep ulcerative complications due to neglect.
