Gene delivery using self-assembled polyplexes, formed between negatively charged nucleic acids and cationic polymers, have several drawbacks including low transgene expression and toxicity effects related to their positive charge. Recently, a novel cationic polymer based on dextran–spermine (D–SPM) was developed for gene delivery. This polymer showed systemic biodistribution upon local administration...
Submicron emulsions of miconazole were stabilized by using a combination of three emulsifiers comprising phospholipids, poloxamer, and deoxycholic acid (DCA). The presence of DCA was vital for prolonged emulsion stability owing to its contribution to the elevated zeta potential of the emulsion. Further, the results by the phospholipid surface labelling colorimetric technique clearly suggested that...
