Figures for Mucoadhesion

Mode of action of mucoadhesion. Dry mucus will not adhere to a mucoadhesive, but in the presence of moisture the mucus becomes plastic and can form intermolecular bonds.

Places where fractures can occur when testing fracture theory. Fracture theory looks for force required to separate at the interface, but fractures can occur due to cohesive failure within either of the layers.

Interpenetration of a bioadhesive with mucus. In the contact stage, the two materials are brought into contact. In the consolidation stage the interpenetration of the polymers occurs.

Interpenetration of a bioadhesive with mucus. Interpenetration occurs after a certain time, t.
