Immunosensing of Trinitrotoluene using Sol-Gel Glasses
Research in recent years has demonstrated that biological molecules such as enzymes, immunoglobulins, and other proteins can be immobilized in sol-gel derived matrices and retain their biological function. Development ofglasses with encapsulated biomolecules has opened the possibility of solid-state optical biosensors for the detection and measurement of desired analytes. In this work, we repor...
متن کاملAnalysis of Bioactive Glasses Obtained by Sol-Gel Processing for Radioactive Implants
This paper presents the chemical and physical characterizations of SiO 2 and SiO 2 -CaO bioactive glasses incorporated with samarium atoms, produced by sol-gel synthesis. The objective is to provide biocompatible and biodegradable radioactive seeds as an alternative to be used in Brachytherapy for the treatment of prostate cancer. The glasses were produced and analyzed by X-ray fluorescence spe...
متن کاملSynthesis of quantum dot doped chalcogenide glasses via sol-gel processing
Semiconductor quantum dots (QDs) are used to dope wide-bandgap chalogenide glasses via sol-gel processing. Such chalcogenides enhance surface passivation of the quantum dots, as evidenced by the increased PL emissions of both core and core shell species used, while a ZnO glass leads to irreversible oxidation of the embedded quantum dots. The embedded QDs are photostable. VC 2011 American Instit...
متن کاملSynthesis, characterization, of Fluorohydroxyapatite nanopowders by sol-gel processing
In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...
متن کاملSol-Gel Processing of Nanostructured Inorganic ScintillatingMaterials
The development of scintillating materials is believed to reach a new step by controlling their preparation on a nanometric level. Sol-Gel chemistry offers very unique tools for nanoscale mastering of the materials preparation. In particular, shaping of the materials as thin films or nanoparticles offers new application in medical imaging. The control of doping ions dispersion thanks to soft ch...
