Bioadhesion mechanism |
Electrostatic: Electrostatic forces between the tissue and the bioadhesive material. |
Wetting: Ability of the bioadhesive to spread and develop intimate contact with the target surface. |
Adsorption: Surface forces resulting in chemical bonding between the target material and the bioadhesive. |
Diffusion: Results in physical entanglements of the tissue and the bioadhesive’s flexible polymer chains. |
Mechanical: Interlocking of the bioadhesive into irregularities on the rough surface of the tissue. |
