Protein adsorption onto organically modified silica glass leads to a different structure than sol-gel encapsulation.
The secondary structures of two proteins were examined by circular dichroism spectroscopy after adsorption onto a series of organically modified silica glasses. The glasses were prepared by the sol-gel technique and were varied in hydrophobicity by incorporation of 5% methyl, propyl, trifluoropropyl, or n-hexyl silane. Both cytochrome c and apomyoglobin were found to lose secondary structure af...
متن کاملMolecular dynamics simulations of organically modified layered silicates
Molecular dynamics ~MD! simulations are used to study the static and dynamic properties of 2:1 layered silicates ion exchanged with alkyl-ammonium surfactants. These systems are in the form of oligomeric alkanes grafted by cationic groups on atomically smooth crystalline layers 10 Å thick and several microns wide. The organically modified layers self-assemble parallel to each other to form alte...
متن کاملZnO films prepared by modified sol-gel technique
Zinc oxide films with different thicknesses have been synthesized by modified sol-gel technique. The films are polycrystalline in nature with average grain size between 32 and 57 nm. The thicker films are less strained than the thinner ones. The optical band gap of the films is ~ 3.22 eV. PL spectra are dominated by a strong luminescence peak at ~387 nm followed by a low intensity peak ~469 nm....
متن کاملNano-structured ZnO films by sol-gel process
Thin films of ZnO grown by sol-gel spin method using two different precursors viz. zinc nitrate and zinc acetate have been characterized for their crystalline nature and associated nanostructures. In some cases, the films consist of nanostructures in the form of nanocrystals and nanoneedles of dimensions in the range 15-60 nm. A comparison between the physical characterization and the nanostruc...
متن کاملBaFe12O19 thin film grown by an aqueous sol-gel process
In this communication we present a new sol–gel route to obtain high quality BaFe12O19 thin films. X-ray analysis confirmed the crystal structure with a crystal size of 32 nm. Atomic force microscopy images determined the film thickness to be around 250 nm and a roughness factor of less than 40 nm where the grain size averaged around 150 nm. SQUID magnetometer data shows a magnetic behavior simi...
