abstract = {The objective of the present investigation was to evaluate
nano-dispersed systems of differently chained lipids (solid
phases) using various scattering techniques. Nanostructured
lipid carriers (NLCs) were fabricated by employing the
microemulsification methodology in which dialkyldimethyl
ammonium bromide (DxDAB) of different alkyl chain length
(x=12, 14, 16, 18) and oleic acid were used as the solid
lipid and liquid lipid, respectively. For the first time,
the effect of DxDAB as a function of the chain length of the
double alkyl chain on the structural characteristics of NLCs
was investigated. Dynamic light scattering (DLS) and static
light scattering (SLS) results showed that a small but
systematic size increase occurs with increase in the chain
length ‘x’ of the DxDAB from 12 to 16, yet D18DAB based
NLCs exhibited the smallest size irrespective of its higher
hydrophobicity. Small angle neutron scattering (SANS)
analysis revealed the structural make up of NLCs having
spherical nanoparticles and triaxial ellipsoidal core-shell
micelles in the system. In-vitro cytotoxicity evaluation
indicated that toxicity is simply concentration-dependent
phenomena and NLCs with less than 5 mg/mL are preferred for
better in-vivo tolerance.},
