1. Surface Area: A larger surface area allows for more interaction sites, enhancing absorption efficiency. 2. Functionalization: Modifying the surface of nanomaterials with specific functional groups can improve their selectivity for certain molecules. 3. Particle Size: Smaller particles have higher surface energy, which can increase their absorption capabilities. 4. Environmental Conditions: Temperature, pH, and the presence of other substances can affect the absorption efficiency of nanomaterials.
