The aim of the present work was to develop and characterize two different nanosystems, nanospheres and nanocapsules, containing either xanthone (XAN) or 3-methoxyxanthone (3-MeOXAN), with the final goal of improving the delivery of these poorly water-soluble compounds. The xanthones-loaded nanospheres (nanomatrix systems) and nanocapsules (nanoreservoir systems), made of poly(DL-lactide-co-glyc...

We have synthesized plasmonic nanocapsules and studied their induced cellular responses in 3D melanoma models towards its perspective use as photothermal therapeutic agent. The nanocapsules’ wall is composed of polyelectrolytes. inner part functionalized with discrete gold nanoislands. cavity contains a fluorescent payload to show ability for loading cargo. exhibit simultaneous two-photon lumin...

The improvement of the rutin photostability and its prolonged in vitro antioxidant activity were studied by means of its association with nanostructured aqueous dispersions. Rutin-loaded nanocapsules and rutin-loaded nanoemulsion showed mean particle size of 124.30 ± 2.06 and 124.17 ± 1.79, respectively, polydispersity index below 0.20, negative zeta potential, and encapsulation efficiency clos...

Platinum-based drugs are widely used in cancer chemotherapy. However, their clinical use is limited by systemic toxicity, rapid blood clearance, and the occurrence of resistance. Our research is aimed at increasing the therapeutic index of these drugs by encapsulation in a lipid formulation. Previously, we developed a method for efficient encapsulation of cisplatin in a lipid formulation, yield...

INTRODUCTION Nanocapsules, existing in miniscule size, range from 10 nm to 1000 nm. They consist of a liquid/solid core in which the drug is placed into a cavity, which is surrounded by a distinctive polymer membrane made up of natural or synthetic polymers. They have attracted great interest, because of the protective coating, which are usually pyrophoric and easily oxidized and delay the rele...

Hollow polymeric nanocapsules have attracted great interest in recent years due to their broad applications in controlledrelease carriers, catalysis, nanoreactors, and encapsulation of guest molecules. Polymeric nanocapsules have been typically fabricated via the selfassembly of block copolymers, 5 polymerization within lipid vesicles, emulsion polymerization, 14 and the sacrificial core-templa...

Recently, nanobiotechnology has a very wide range of applications, and one them is the application nanoparticles for delivery systems active substances. Nanoparticles are most unique entities that enhance performance, expand provide an opportunity to develop materials can address many scientific challenges. Hollow nanoparticles-nanocapsules built from plant proteins have suitable physico-chemic...

The fabrication of polymer nanocapsules with tailored dimensions has been accomplished by microemulsion polymerization using different surfactants.

It is challenging to image fluorescence objects with high spatial resolution in a highly scattering medium. Recently reported temperature-sensitive indocyanine green-loaded pluronic nanocapsules can potentially alleviate this problem. Here we demonstrate a frequency-domain temperature-modulated fluorescence tomography system that could acquire images at high intensity-focused ultrasound resolut...

The aim of this data article is to provide data for a basic knowledge of the properties of lipid nanocapsules, a new colloidal system with very promising applications in drug delivery. Firstly, we pay attention on how it is possible to determine their surface composition by means of electrokinetics measurements. On the other hand, we provide experimental evidences for a better understanding of ...
