Nanometer-Scaled Hollow Spherical Micelles with Hydrophilic Channels and the Controlled Release of Ibuprofen

Chiral liquid membrane for enantioselective separation of racemic ibuprofen by l-tartaric acid derivatives

Use of a chiral liquid membrane is an attractive separation method for racemic ibuprofen, and the separation factor could be up to 1.38 under optimal experimental conditions.

Self-assembly strategy for the preparation of polymer-based nanoparticles for drug and gene delivery

Nanoparticulate drug-delivery systems have attained much importance because of their injectable property, the possibility to achieve passive targeting and active targeting, and unique advantages to realize stimuli tailored delivery. Molecular self-assembly is a powerful method for fabricating polymer-based nanoparticles, which involves various driving forces, such as hydrophobic interactions, electrostatic interactions, stereocomplexation, host/guest interactions and hydrogen bonding. By fine tuning one or many types of these interactions, self-assemblies with a wide range of structures and functions could be fabricated. In this article, recent developments in different self-assembly strategies for the preparation of polymer-based nanoparticulate delivery systems are discussed.
