How hydrophobic polymers as cellulose and lignin can be used as efficient nanoparticles for poorly water-soluble agent delivery in aqueous environment (blood, extracellular fluid, in vitro culture media) ??
Using appropriate surfactants in biological environments that can accommodate the desired nanoparticles in the environment, otherwise the body's immune system automatically detects and remove the nanoparticles quickly. You really need to increase the biocompatibility of the hydrophobic nanocarreirs with use of substances mentioned above.
