Cationic Niosomes

Cationic niosomes have become important non-viral vehicles for transporting a good number of small drug molecules and macromolecules. Growing interest shown by these colloidal nanoparticles in therapy is determined by their structural similarities to liposomes. Cationic niosomes are usually obtained from the self-assembly of non-ionic surfactant molecules. This process can be governed not only by the nature of such surfactants but also by others factors like the presence of additives, formulation preparation and properties of the encapsulated hydrophobic or hydrophilic molecules. This review is aimed at providing recent information for using cationic niosomes for gene delivery purposes with particular emphasis on improving the transportation of antisense oligonucleotides (ASOs), small interference RNAs (siRNAs), aptamers and plasmids (pDNA).

The behavior of amphiphilic block copolymers in solution has attracted considerable attention in recent years. In this paper, the self-assembly behaviors of the amphiphilic fluorinated ABC-type triblock copolymer (MeOPEO16-PSt220-PFHEA22) in different mixed solutions were studied. Also, the effect of ionic concentration on the self-assembly aggregates of the copolymer in toluene-ethanol-water was studied.

Induced Crystallization

To date, amphiphilic block copolymers (BCPs) containing poly(vinylidene fluoride-co-hexafluoropropene) (P(VDF-co-HFP)) copolymers are rare. At moderate content of HFP, this fluorocopolymer remains semicrystalline and is able to crystallize. Amphiphilic BCPs, containing a P(VDF-co-HFP) segment could, thus be appealing for the preparation of self-assembled block copolymer morphologies through crystallization-driven self-assembly (CDSA) in selective solvents. Here the synthesis, characterization by 1H and 19F NMR spectroscopies, GPC, TGA, DSC, and XRD; and the self-assembly behavior of a P(VDF-co-HFP)-b-PEG-b-P(VDF-co-HFP) triblock copolymer were studied. The well-defined ABA amphiphilic fluorinated triblock copolymer was self-assembled into nano-objects by varying a series of key parameters such as the solvent and the non -solvent, the self-assembly protocols, and the temperature. A large range of morphologies such as spherical, square, rectangular, fiber-like, and platelet structures with sizes ranging from a few nanometers to micrometers was obtained depending on the self-assembly protocols and solvents systems used. The temperature-induced crystallization-driven self-assembly (TI-CDSA) protocol allowed some control over the shape and size of some of the morphologies.

Assembly Behavior

Self-assembly behavior of an cationic amphiphilic triblock copolymer Q-PVBC -b-PS-b-Q-PVBC in DMF/water and DMF/methanol were studied. Well defined triblock copolymer PVBC-b-PS-b-PVBC was synthesized by RAFT polymerization and the cationic amphiphilic block copolymers Q-PVBC-b-PS-b-Q-PVBC was obtained by the quaternization of hydrophobic precursors with triethylamine. It is concluded that that selective solvents had a great effect on the self-assemble morphologies of the polymer. Comparing to the micelles treating water as the selective solvent, the aggregates using methanol were irregular spheres and had larger diameter.
