A) Schematic of the design and assembly of DNA micelles. (Top) Oligonucleotide micelles contain a DNA corona, a pyrene unit (fluorescence reporter), and a lipid core. (Bottom) Molecular structure of pyrene and lipid unit.[29b] Copyright 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim B) Structure of aptamer-coated PLGA hybrid nanoparticles and co-delivery of two drugs to cancer cells. PTX is encapsulated in the PLGA core and DOX is loaded in the lipid-PEG-aptamer shell. Lecithin and DSPE-PEG are used to stabilize the structure.
