Biodegradable anisotropic nanoparticles based on stereocomplexes between enantiomeric polylactides for controlled release of multiple drugs and methods of preparing thereof

摘要

The present invention relates to a first compartment comprising an A block comprising a polymer exhibiting optical isomerism and an ABA block copolymer comprising a B block comprising polyethylene glycol (PEG); And a stereocomplex formed between the optical isomers of the ABA type block copolymer; The drug delivery system comprising an anisotropic nanostructure and a drug delivery system in which the drug is incorporated in each compartment.
