We report the synthesis of ZnSe:Mn quantum dots (QDs) in the dispersed phase of a microemulsion template consisting of p-xylene as the continuous phase, water as the dispersed phase, and an amphiphilic block copolymer (Pluronic P105) as the surfactant. The Zn and Mn precursors were Zn-acetate and Mn-acetate, respectively, dissolved in the aqueous dispersed phase. Hydrogen selenide gas was bubbl...
ABSTRACT: This research aims to prepare microemulsion from Tea Tree and Rosemary essential oil treat gram-positive gram-negative bacterial infections. A phase titration has been used make the proposed microemulsion, which contained 71% water, 23% of a 1:1 mixture propylene glycol (surfactant), tween 80 (co-surfactant), 6% tea tree/rosemary oil. In pale yellowish transparent droplet size, zeta p...
A topical preparation containing aceclofenac was developed using an o/w microemulsion system. Isopropyl myristate was chosen as the oil phase as it showed a good solubilising capacity. Pseudo-ternary phase diagrams were used to obtain the concentration ranges of the oil, surfactant (Labrasol) and co-surfactant (plurol oleique) for microemulsion formation. Five different formulations were formul...
Polydimethylsiloxane (PDMS) has been synthesized by ring-opening polymerization of octamethylcyclotetrasiloxane (D4) in microemulsion with acidic catalyst. The structure and properties of microemulsion were characterized by Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), Photo Correlation Spectroscopy (PCS). The effect of the variation in pH value, amoun...
Objective(s): Sesame oil is a lipophilic compound and has low aqueous solubility and low oral bioavailability. It is possible to enhance sesame oil solubility in aqueous media by applying the microemulsion system in the form of oil-in-water. In this study, the anti-cholesterol and anti-Apoptotic effects of a new combination of sesame oil and honey in a microemulsion form for cardiac muscle cell...
This mini review article, intends to provide the essential information about microemulsion technique as a reliable approach toward the synthesis of zeolitic nano crystallites. The strategy discussed here provides a unique, effective, and potentially general methodology to the preparation of uniform and high purity nano crystallites of template-free zeolitic materials including LTA, faujasite ty...
BACKGROUND Propofol is used as an induction and maintenance agent for general anesthesia but it can cause adverse reactions like hyperlipidemia, growth of microorganisms, and pulmonary embolisms. Microemulsion propofol was developed to avoid these side effects but incidence and severity of pain on injection is higher than with lipid emulsion propofol. We aimed to compare the effects of sufentan...
Background: Sesame oil can be used to treat cardiovascular diseases, such as atherosclerosis, by reducing the levels of fibrinogen and factor VII. The aim of this study is to prepare a microemulsion containing sesame oil as a drug nanocarrier for improving the aqueous solubility and therapeutic effects of this vegetable oil on the reduction of the fibrinogen and factor VII levels in animal mode...
The purpose of this study was to investigate microemulsions as delivery systems for diclofenac sodium (DS). Microemulsion systems were composed of: soybean oil, nonionic surfactants (Brij 58 and Span 80), and different alcohols: ethanol, and 1-buthanol as cosurfactant. The optimum surfactant: cosurfactant (S:CoS) weight ratios and microemulsion areas were detected by the aid of ternary phase di...
The effect of a doubly hydrophobically end-capped water soluble polymer (C18-PEO150-C18) on the properties of an oil-in-water (O/W) droplet microemulsion (R ∼ 2.85 nm) has been studied as a function of the amount of added telechelic polymer. Macroscopically one observes a substantial increase of viscosity once a concentration of ∼5 hydrophobic stickers per droplet is surpassed and effective cro...
