This contribution discusses methods for transferring exogenous materials and drugs, particularly, into biological tissues. The focus is on matrices such as micelles, vesicles, and oil-based dispersions as well as carbon nanotubes. An ensemble of physical forces takes a fundamental role in drug dispersion and includes van der Waals (vdW), steric (ST), double layer, (DL), osmotic (OS), etc. Combination of these forces is responsible for drug uptake in matrices and for their release in tissues.
