Hint: Through attraction factors like Van der Waals forces, target species are bound and accumulated. It uses hydrogen bonds, van der Waals forces, electrostatic interactions, and hydrophobic interactions to bind the target substance on a chip.
Complete Step by Step Solution:
We know that,
Physical adsorption, Van der Waals adsorption, or physisorption are all terms used to describe the adsorption process in which molecules of the adsorbate are kept on the surface of the adsorbent by weak physical forces.
Physical adsorption, also known as physisorption, is a process in which the atoms or molecule's electronic structure is little altered as a result of adsorption.
Therefore, the correct answer is physical adsorption.
Hence, the correct answer is (A).
Additional Information: According to Le-principle, Chatelier's physical adsorption is an exothermic process that becomes less effective as the temperature rises. Any gas can be adsorbed on the adsorbate during physical adsorption. Porous materials are also superior adsorbents because they have a higher surface area, which boosts adsorption.
Physisorption develops as a result of weak physical forces known as van der Waals forces. The forces that lead to the condensation of gas into liquid are analogous to van der Waals forces.
Note: It must be noted that, Another significant phenomena that helps to stabilise the tridimensional protein structure is the van-der-Waals interaction. Van-der-Waals interactions, when considered separately, are weak attractions between molecules that are close to one another. The London Dispersion Forces are another name for them.
