The advantages of using collagen include:

• it is available in abundance and easily purified from living organisms. More than 30% of vertebrate tissues have collagen.

• orientation of fibers

• semipermeability of membranes

• positive effect on wound healing rates

• non-antigenic - since the fibers are abundant in nature they do not cause a reaction of the immune system.

• non-toxic and biocompatible

• biodegradable and bioreabsorbable - biodegradability can be regulated by cross-linking

• biological plastic due to high tensile strength and minimal expressibility

• synergic with other used bioactive components and compatible with synthetic polymers

• formulated in a number of different forms

• promotes blood coagulation

• easily modifiable to produce materials as desired by utilizing its functional groups
