Solid lipid nanoparticles (SLNs) may be considered as a new approach for therapeutics for many diseases. In addition to drug delivery, their use as non-viral vectors for gene delivery can be obtained by including cationic lipids, which provide a positive

Mode-of-action studies concluded that alkyldimethylbenzylammonium chloride (ADBAC) (a blend of C(12), C(14) and C(16) alkyl homologues) and didecyldimethylammonium chloride (DDAC) are both membrane-active agents, possessing subtly different modes of action reflecting early cell interactions against Staphylococcus aureus. ADBAC and DDAC

Nanomaterials with particular nanostructures which usually possess special properties always attract considerable attention. A novel bimetallic Pt/Cu hexapod nanostructure was prepared by a facile one-pot strategy. The formation mechanism was investigated by the time sequential evolution experiments and the hexapod

Despite considerable interest and investigations on cationic lipid-DNA complexes, reports on lipid-RNA interaction are very limited. In contrast to lipid-DNA complexes where lipid binding induces partial B to A and B to C conformational changes, lipid-tRNA complexation preserves tRNA folded

In this work, we aimed at developing an improved topical SLN formulation combining itraconazole delivery with a coating layer of didodecyldimethylammonium bromide, thus repurposing the drug effectiveness by synergistic skin anticancer effectiveness. In order to obtain a stable SLN formulation
