Gold Nanoparticle-Enhanced Photodynamic Therapy from Photosensitiser-Entrapped Ormosil Nanoparticles.

Journal of Nanoscience and Nanotechnology, 2019
Herein, we investigate the effect of the surface attachment of gold nanoparticles (AuNPs) on photosensitiser-entrapped organically modified silica (ormosil) nanoparticles for enhanced photodynamic therapy (PDT).

P-Containing ORMOSILS for bone reconstruction

Progress in Solid State Chemistry, 2006
Abstract PDMS–CaO–SiO 2 –phosphatoethylsilane (PES) ORMOSILS with different P content were prepared as monoliths. The use of a phosphorous source such as diethyl phosphatoethyl triethoxysilane (DEPETES) allowed the introduction at a molecular level of P into an ORMOSIL network.

Optical limiting property of gold nanorods/ormosil gel glass composites

Optics Communications, 2019
Sol–gel derived ormosil gel glass can act as matrix for different functional molecules or nanomaterials due to its many advantages. Gold and silver colloidal nanoparticles have great application potential in nonlinear optical field due to their ultrafast

Zirconia-ormosil films doped with PbS quantum dots

Journal of Non-Crystalline Solids, 1999
Abstract Zirconia-ormosil (organically modified silicates) films doped with different concentrations of PbS quantum dots were synthesized by sol–gel processing. A sol containing 3-(trimethoxysilil)propylmethacrylate as matrix precursor was mixed with a PbS colloidal doping sol.

Structural investigation of ormosils with potential as host photonic materials

Journal of Sol-Gel Science and Technology, 1997
Class II ormosils in the systems: methyl, propyl, vinyl and phenyl silicates have been structurally investigated for their suitability as photonic materials and this paper is a precis of many data. From visible and near-infrared spectroscopy these ormosils have: (i) intrinsic optical windows in the visible and at 1.06, 1.3 and 1.55 μ m and (ii) low ...

Polarity studies on ormosils using a solvatochromic fluorescent probe†

The Analyst, 1998
Ormosils (organically modified siloxanes) are a relatively new family of materials, prepared by the sol–gel method, with properties that are intermediate between those of glasses and polymers. To probe the micropolarity of various solvents and ormosils, a ketocyanine dye (KC) with unique solvatochromic properties in fluorescence was used.

Ormosil Nanocomposite Materials as Modifiers for Acrylic Coating Systems

Journal of Nanoscience and Nanotechnology, 2006
Organically modified silica (ormosil) particles were prepared using hydrolytic sol-gel methods and the miniemulsion polymerisation approach. Methyl-, ethyl-, and phenylsilsesquioxane nanoparticles with diameters in the range 50-180 nm were obtained using the modified Stöber method with an aqueous sodium silicate solution used as a seed for further ...

Ormosil-Nafion Composite Membranes for PEM Fuel Cells

ECS Transactions, 2006
Composite Nafion-based membranes were prepared and characterized, using an organosilane derivative (sulfonated diphenylsilanediol, SDPSD) as a filler. The formation of the composite substantially modified the properties of the Nafion matrix in terms of proton conductivity and thermal stability.
