Folic Acid-Doxorubicin-Double-Functionalized-Lipid-Core Nanocapsules: Synthesis, Chemical Structure Elucidation, and Cytotoxicity Evaluation on Ovarian (OVCAR-3) and Bladder (T24) Cancer Cell Lines.

Purpose: Folic acid-doxorubicin-double-functionalized-lipid-core nanocapsules (LNC-CS--Zn-DOX-FA) were prepared, characterized, and evaluated in vitro against ovarian and bladder cancer cell lines (OVCAR-3 and T24).

Methods: LNC-CS--Zn-DOX-FA was prepared by self-assembly and interfacial reactions, and characterized using liquid chromatography, particle sizing, transmission electron microscopy, and infrared spectroscopy. Cell viability and cellular uptake were studied using MTT assay and confocal microscopy.

Larvae as an Model to Evaluate the Toxicity of Polymeric Nanocapsules.

larvae is an invertebrate that has been extensively used as experimental model in the investigation of microbial virulence and efficacy of antimicrobial agents and can be used to provide faster and cheaper data than traditional test systems. Our objective was to propose the use of larvae as an model to evaluate the toxicity of lipid-core nanocapsule (LNC) formulations having different surface coatings. Blank LNC formulations were coated with polysorbate 80 (LNC-1), lecithin and polysorbate 80 (LNC-2), and lecithin, chitosan and polysorbate 80 (LNC-3).
