[PMID: 31170324 DOI: 10.1002/jgm.3101] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 05/25/2019] [Accepted: 05/29/2019] [Indexed: 12/15/2022] Open
Abstract
Micelles have demonstrated an excellent ability to deliver several different types of therapeutic agents, including chemotherapy drugs, proteins, small-interfering RNA and DNA, into tumor cells. Cationic micelles, comprising self-assemblies of amphiphilic cationic polymers, have exhibited tremendous promise with respect to the delivery of therapy genes and gene transfection. To date, research in the field has focused on achieving an enhanced stability of the micellar assembly, prolonged circulation times and controlled release of the gene. This review focuses on the micelles as a nanosized carrier system for gene delivery, the system-related modifications for cytoplasm release, stability and biocompatibility, and clinic trials. In accordance with the development of synthetic chemistry and self-assembly technology, the structures and functionalities of micelles can be precisely controlled, and hence the synthetic micelles not only efficiently condense DNA, but also facilitate DNA endocytosis, endosomal escape, DNA uptake and nuclear transport, resulting in a comparable gene transfection of virus.

Abstract
A surfactant-free emulsion-based approach is developed for preparation of nanogels. A water-in-oil emulsion is generated feasibly from a mixture of water and a solution of disulfide-containing hyperbranched PEGylated poly(amido amine)s, poly(BAC2-AMPD1)-PEG, in chloroform. The water droplets in the emulsion are stabilized and filled with poly(BAC2-AMPD1)-PEG, and the crosslinked poly(amido amine)s nanogels are formed via the intermolecular disulfide exchange reaction. FITC-dextran is loaded within the nanogels by dissolving the compound in water before emulsification. Transmission electron microscopy and dynamic light scattering are applied to characterize the emulsion and the nanogels. The effects of the homogenization rate and the ratio of water/polymer are investigated. Redox-induced degradation and FITC-dextran release profile of the nanogels are monitored, and the results show efficient loading and redox-responsive release of FITC-dextran. This is a promising approach for the preparation of nanogels for drug delivery, especially for neutral charged carbohydrate-based drugs.

Abstract
Generally, it is very difficult to control the size of large compound vesicles. Here, we introduce a novel method for the preparation of biodegradable large compound vesicles with controlled size and narrow size distribution by using aqueous nanodroplets as templates.
