Also included are pharmaceutical compositions containing the dendron-micelles, methods of making the dendron-micelles, and therapeutic methods including administering the dendron-micelles to a subject in need thereof.

A pharmaceutical composition containing a mixed polymeric micelle and a drug enclosed in the micelle, in which the mixed polymeric micelle, 1 to 1000 nm in size, includes an amphiphilic block copolymer and a lipopolymer. Also disclosed are preparation of the pharmaceutical composition and use thereof for treating cancer.

Described herein are therapeutic pH responsive compositions comprising a block copolymer and a therapeutic agent useful for the treatment of cancer.

Provided herein are nanoparticle-lipid composite carriers as theranostic agents, particularly for diagnosis and/or treatment of cancers and related diseases and conditions. In particular embodiments, the carrier composites comprise a lipid core and an outer shell of functionalized nanoparticles (fNPs).

Disclosed herein are conjugated polymers comprising a polymer and an all-trans retinoic acid (ATRA) prodrug covalently bound to the polymer by a hydrolysable linker L or a pharmaceutically acceptable salt thereof, and methods of using same to treat certain disorders. In an embodiment, the conjugated polymer comprises poly (vinyl alcohol) covalently bound to ATRA through an ester linkage.

Provided herein are glycosylated peptide amphiphiles (GPAs), supramolecular glyconanostructures assembled therefrom, and methods of use thereof. In particular, provided herein are glycosaminoglycan (GAG) mimetic peptide amphiphiles (PAs) and supramolecular GAG mimetic nanostructures assembled therefrom that mimic the biological activities of GAGs, such as heparin, heparan sulfate, hyaluronic acid etc.

Disclosed herein are nanoparticle compositions containing that may be created by functionalizing polyethylenimine (PEI) with fatty acids and carboxylate terminated poly(ethylene glycol) (PEG). The disclosed compositions may be delivered to an individual in need thereof via delivery into blood circulation, where the nanoparticle compositions show an exceptionally high specificity to the pulmonary microvascular endothelium with minimal targeting of other cell types in the lung, to provide delivery of therapeutic agents such as stabilized nucleic acids. Methods of using the compositions are also disclosed.

The present invention relates to a gas-generating micelle for reducing localized fat. In the present invention, by forming a micelle using a material having high biocompatibility and also introducing a cell-targeting ligand (peptide) onto the surface of the micelle, delivery to surrounding cells and tissues other than adipocytes can be minimized, and delivery into adipocytes can be maximized. The gas-generating micelle for reducing localized fat according to the present invention can be produced as an injectable preparation, and can be applied to local lipolysis supplements or diet beauty products that break down localized fat.

Provided herein are block copolymers comprising a hydrophilic polymer segment and a hydrophobic polymer segment, wherein the hydrophilic polymer segment comprises a polymer selected from the group consisting of: poly(ethylene oxide) (PEO), poly(methacrylate phosphatidyl choline) (MPC), and polyvinylpyrrolidone (PVP), wherein the hydrophobic polymer segment comprises
