Magnetic nanoparticles that are currently explored for various biomedical applications exhibit a high propensity to minimize total surface energy through aggregation. This study introduces a unique, thermoresponsive nanocomposite design demonstrating substantial colloidal stability of superparamagnetic Fe3O4 nanoparticles (SPIONs) due to a surface-immobilized lipid layer. Lipid coating was acco...

The present review compiles the applications of lipid nanoparticles mainly solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) for the delivery of pharmaceutical actives. The attempts to overcome the low solubility and bioavailability of some drugs by their incorporation into lipid nanocarriers have been summarized. A special focus of this review is on different routes of ad...

INTRODUCTION Gemcitabine hydrochloride is an antimetabolite (pyrimidine analog) with poor oral bioavailability (9%) due to the first pass metabolism. GEM is a water soluble drug (log p = -1.4) with a short half-life of 42 to 94 minutes (short infusions) and 245 to 638 minutes (long infusions) respectively. Extensive first pass metabolism, low bioavailability, high dosing frequency and less half...

This paper aims to encapsulate into solid lipid nanoparticles a mixture of two bioactive compounds, a photoprotective agent and an antioxidant compound. The co-encapsulation effect of octocrylene sunscreen and flavonoid (luteolinon) has been studied on the specific properties like antioxidant activity, sun protection factor and photostability. Using the high preasure homogenization technique li...

Topical delivery has the advantages including being user friendly and cost effective. Development of topical delivery carriers for lutein is becoming an important issue for the ocular drug delivery. Quantification of the partition coefficient of drug in the ocular tissue is the first step for the evaluation of delivery efficacy. The objectives of this study were to evaluate the effects of lipid...

Colloidal lipid particles such as solid lipid nanoparticles and liquid crystalline nanoparticles have great opportunities as drug carriers especially for lipophilic drugs intended for intravenous administration. In order to evaluate drug release from these nanoparticles and determine their behavior after administration, emulsion droplets were used as a lipophilic compartment to which the transf...

Lipid nanoparticles (LNP) are promising soft matter nanomaterials for drug delivery applications. In spite of their interest, little is known about the supramolecular organization of the components of these self-assembled nanoparticles. Here, we present a molecular dynamics simulation study, employing the Martini coarse-grain forcefield, of self-assembled LNPs made by tripalmitin lipid in water...

Small interfering RNA (siRNA) is a highly potent drug in gene-based therapy with a challenge of being delivered in a sustained manner. Nanoparticle drug delivery systems allow for incorporating and controlled release of therapeutic payloads. We demonstrate that solid lipid nanoparticles can incorporate and provide sustained release of siRNA. Tristearin solid lipid nanoparticles, made by nanopre...

We report that Fe3O4 nanoparticles are able to catalyse lipid peroxidation in liposomes at acidic but not neutral pH. The oxidation is dependent on either pre-existing lipid peroxides or hydrogen peroxide as a substrate. This is the first evidence for metal oxide nanoparticles as peroxidase mimetics oxidising biomolecules in a relevant environment.
