Mesoporous silica nanoparticles (MSNs), based on the MCM-41 matrix, were functionalized with amino groups, and then with hyaluronic acid (HA) or chitosan (CHIT) to fabricate bioactive conjugates. The role of the functional groups toward cytotoxicity

Gold-iron oxide composites were obtained by in situ reduction of an Au(III) precursor by an organic reductant (either potassium citrate or tiopronin) in a dispersion of preformed iron oxide ultrasmall magnetic (USM) nanoparticles. X-ray diffraction,t

Ordered mesoporous silica (OMS) materials are receiving great attention as possible carriers for valuable but unstable drugs as, for example, therapeutic proteins. A key issue is to prove that the therapeutic protein is effectively able to penetrate

Effect of oxidation level of n(+)-type mesoporous silicon surface on the adsorption and the catalytic activity of Candida rugosa lipase

Publikováno v: Journal of colloid and interface science. 345(2)

In this work, we present the synthesis and characterization of n + -type porous silicon (PSi) layers. Our final aim is the fabrication of a biosensor that exploits the semiconductive properties of this material. PSi wafers were used as a matrix for e

Hofmeister series reversal for lysozyme by change in pH and salt concentration: insights from electrophoretic mobility measurements

Autor: Andrea Salis, Francesca Cugia, Maura Monduzzi, Drew F. Parsons, Barry W. Ninham

Publikováno v: Physical Chemistry Chemical Physics. 14:4343

Hofmeister series reversal can occur with change in pH, or increase in salt concentration. The phenomena are a challenge for any theory of ion specific effects. Recent theoretical work predicts how a complex interplay between ionic sizes, hydration a
