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...

The correlation between the textural properties and the photocatalytic activity of nanocrystalline Titanium dioxide (TiO2)-anatase films obtained by sol–gel has been investigated. Mesoporous and mesostructured TiO2-anatase films were prepared using different titanium precursors and Pluronic (F127) and polyethylene glycol hexadecyl ether P5884 (Brij58) surfactants via acid catalysis. Ca(NO3)2 an...

Using a test mixture consisting of standard proteins (cytochrome c, chymotrypsinogen A, hen egg albumin, bovine serum albumin, aldolase, catalase and ferritin) and synthetic polypeptides (polylysine, polyaspartic, polyglutamic acid and polyproline) it was revealed that using sodium dodecyl sulfate (SDS) as background electrolyte modifier at acid pH (2.5) allows selective separation of highly po...

In the present study solid dispersions of the antifungal drug Ketoconazole were prepared with Pluronic F-127 and PVP K-30 with an intention to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, Differential scanning calorimetery (DSC), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obta...

Pluronic poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers are grafted with poly(vinyl pyrrolidone) by free radical polymerization of vinyl pyrrolidone with simultaneous chain transfer to the Pluronic in dioxane. This modified polymer has both thermal responsiveness and remarkable capacity to interact with a wide variety of hydrophilic and hydrop...

The objective of this study was formulation and evaluation of mucoadhesive nanoparticles of acyclovir. Nanoparticles were prepared by one step desolvation method by using gelatin as a mucoadhesive polymer. The effects of amount of gelatin and Pluronic F-68 on particle size, polydispersity index, entrapment efficiency, loading efficiency, mucoadhesive strength were studied. Nanoparticulate formu...
