Direct Formation

Hydrophilic honeycomb films are directly fabricated by the self-assembly of complexes of polylacticacid and dodecyl trimethyl ammonium chloride in ‘breath figure’ templating. The presence of a cationic surfactant not only improves film regularity, but also imparts them with excellent wettability.

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).

One Step

Non-close-packed breath figure arrays were observed to form at the periphery of close-packed arrays. We propose a mechanism for their formation and show a proof-of-concept that these non-close-packed pore arrays are formed due to a reversal of breath figure formation, and hence introduce a novel route to the self-assembly of such non-close-packed structures.

Materials Used

Cationic surfactant alkyl trimethyl ammonium chloride was synthesized by quartenerisation of tertiary amines. Materials used in quartenerization are tertiary amine and alkyl halide. Alkyl halide is a hydrocarbon derivative in which one or more hydrogen is replaced with halogen. In this research, thionyl chloride is used as a reactant . Thionyl chloride (SOCl2) is often used because it is easier to make, the yield is greater and byproducts are volatile. Alkyl halide is synthesized from the reaction of hexadecyl alcohol with thionyl chloride (SOCl2) at a temperature of 80 C for 24 hours in a reflux reactor. This study managed to get hexadecyl chloride from the reaction hexadecyl alcohol and thionyl chloride. It can be seen from the results of FTIR, LC/MS and GC/MS
