Lipid shell lipid nanocapsules as smart generation lipid nanocarriers

2019, Materials Science and Engineering CCitation Excerpt :This ‘drop’ of injected LNCs remained as is for the duration of the experiments and did not diffuse throughout the tissue. This can be attributed to the direct injection into the tissue; since the LNCs circumvent the washout and biodistribution associated with an intravenous injection [36–39] this allows for the formulation's sustained presence within the tissue. Thus, the persistence of a ‘drop’ of injected LNCs within the tissue is to be expected, as the normal gastrocnemius muscle is a highly hierarchized tissue and the bolus injection takes place over a short period of time, thus not allowing the liquid to disperse throughout the tissue.
Intracellular availability of poorly soluble drugs from lipid nanocapsules
2019, European Journal of Pharmaceutics and BiopharmaceuticsCitation Excerpt :Lipophilic 99mTc-oxine incorporated in the lipid core of LNCs remained inside the particles even when submitted to aggressive release conditions such as dialysis. This made the labeled nanoparticles an ideal tool to evaluate LNC biodistribution in vivo [74]. In summary, these results raise doubts as to whether it is possible to improve the intracellular bioavailability of poorly soluble drugs by the encapsulation into lipid nanoparticles.

2014, Journal of Controlled ReleaseCitation Excerpt :In a previous study, the co-labeling of LNEs with the DiD dye and two radiotracers led to different elimination phases in vivo depending on the imaging agent [40]. Similarly, a first attempt to monitor the LNC integrity was carried out through the co-labeling of the LNC shell with 125I and LNC core with 99mTechnetium-oxine [40]. However, both radionuclides showed distinct distributions which did not permit to evaluate the LNC integrity.
Quantitative assessment of nanoparticle surface hydrophobicity and its influence on pulmonary biocompatibility
2014, Journal of Controlled ReleaseCitation Excerpt :Nanoparticles fabricated from two different grades of polyvinyl acetate (PVAc) were included as representative of polymeric systems previously investigated to serve as inert reference particles in inhalation toxicology studies [30] and are also found in some aerosolized consumer products, including hairsprays [31]. Two lipid nanocapsule (LNC) formulations (nanocarriers characterized by a liquid triglyceride core and a solidified phospholipid shell containing pegylated 12-hydroxystearate) were included in the study to exemplify promising nanomedicine formulations for pulmonary delivery of poorly soluble compounds [32–36]. The nanoparticle systems included in the study were designed such that they would display a range of surface hydrophobicities.
