Pick the correct pair.

The correct pairing of "Steric Stabilization forces - repulsive force" is significant in the context of tissue engineering and material science. Steric stabilization refers to the mechanism where large polymer chains or grafted molecules occupy space around particles, preventing them from coming too close to each other. This creates a form of repulsion between the particles, enhancing the stability of colloidal suspensions or surfaces by reducing the likelihood of aggregation or flocculation.

In practice, if particles are stabilized sterically, they maintain a distance from one another due to these repulsive interactions. This concept is crucial when formulating hydrogels or composite materials in tissue engineering, where ensuring the proper dispersion of different components is essential for achieving desirable mechanical and biological properties.

Others options might involve forces that can act differently under varying conditions, such as Van der Waals forces which are generally weak attractive forces, or electrostatic forces that may vary based on charge interactions. Polar forces can also attract, depending on the molecules involved and their orientation. However, the unique role of steric stabilization in providing repulsive interactions makes it a fundamental principle worth noting in tissue engineering applications.
