High-purity Cu nanocrystal synthesis by a dynamic decomposition method.

Cu nanocrystals are applied extensively in several fields, particularly in the microelectron, sensor, and catalysis. The catalytic behavior of Cu nanocrystals depends mainly on the structure and particle size. In this work, formation of high-purity Cu nanocrystals is studied using a common chemical vapor deposition precursor of cupric tartrate.

Nanostructured lipid carriers as novel ophthalmic delivery system for mangiferin: improving in vivo ocular bioavailability.

The aim of this study was to develop a novel nanostructured lipid carriers (NLCs) system to improve ocular bioavailability of mangiferin (MGN) for the potential treatment of cataract. The physicochemical properties of MGN-loaded NLC (MGN-NLC) formulation were characterized by particle size, polydispersity index, zeta potential, entrapment efficiency, drug loading, morphological property, and crystalline state. in vitro characteristics were investigated by drug release from NLC system, physical stability, and corneal permeation through excised rabbit cornea.

Gelucire44/14 as a novel absorption enhancer for drugs with different hydrophilicities: in vitro and in vivo improvement on transcorneal permeation.

The objective of this study was to investigate the application of Gelucire44/14 as a novel absorption enhancer in ophthalmic drug delivery system. Six compounds, namely ribavirin, puerarin, mangiferin, berberin hydrochloride, baicalin, and curcumin in the order of increasing lipophilicity were selected as model drugs. The effect of Gelucire44/14 on transcorneal permeation was evaluated across excised rabbit cornea.
