What Factors Affect Dermal Absorption of Nanoparticles?
The dermal absorption of nanoparticles is influenced by several factors:
Particle Size: Smaller nanoparticles can penetrate deeper into the skin layers. Surface Charge: Positively charged particles often show better skin penetration. Surface Modifications: The presence of specific ligands can enhance targeted delivery and absorption. Formulation Matrix: The base formulation (e.g., creams, gels) can impact the absorption rate.
