Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events ...
A similarly strong, rapidly adhering glue - which contains 171 different proteins and can adhere to wet, moist and impure surfaces - is produced by the very hard [5] [6] limpet species Patella vulgata; this adhesive material is a very interesting subject of research in the development of surgical adhesives and several other applications.
Moisture cure polyurethanes have been widely used in the adhesive and coating industries. Thermal, mechanical, and surface properties of hyperbranched polyurethane-urea (HBPU) moisture cured coatings have been studied in relationship to chemical structure. [3]
It allows the movement of water vapor, oxygen, and carbon dioxide into and out of the dressing. It also plays an additional role in autolytic debridement (removal of dead tissue) which is less painful when compared to manual wound debridement inside the operating theater. It is highly elastic and flexible, thus is closely adhered to the skin.
Body marbling on hand. Body marbling is a painting process similar to paper marbling, in which paint is floated on water and transferred to a person's skin.Unlike the traditional oil-based technique for paper, neon or ultraviolet reactive colours are typically used, and the paint is water-based and non-toxic.

In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
