Surfactants: The “Invisible Engineers” Behind Nanomedicine — and Why PEG Matters So Much
Surfactants are one of the key materials behind modern nanomedicine. These amphiphilic molecules contain both hydrophilic and hydrophobic structures, allowing them to reduce surface tension and stabilize systems such as liposomes, micelles, nanoemulsions, and nanocrystals. Traditional drug formulations often face major limitations: Poor water solubility Low bioavailability Rapid clearance in the body Difficulty achieving targeted…
