Magnetic C-C@Fe3O4 hollow microspheres were prepared by using aerosol-based Fe3O4@C-SiO2 core-shell particles as templates. The magnetic double-shelled microspheres efficiently worked as carriers to load Pt nanoparticles, thus making the catalyst recyclable and reusable.

Magnetic porous microspheres are widely used in modern wastewater treatment technology due to their simple and quick dye adsorption and separation functions. In this article, we prepared porous polymethylmethacrylate (PMMA) microspheres by the seed-swelling method, followed by in situ formation of iron oxide (Fe₃O₄) nanoparticles within the pore. Then, we used diazo-resin (DR) to encapsulate th...

Drug delivery systems have been used in cancer treatment to increase drug effectiveness. The hydroxyapatite (HAP) based materials this area can provide transport the target site without its deterioration. In study, porous hollow microspheres (PHHMs) were produced by using hydrothermal method. Tamoxifen (TAM) of breast has covalently attached microspheres. obtained microsphere structures (tamoxi...

In the present study, we tested the hypothesis that similar to other mechanical loads, notably cyclic stretch (simulating pre-load), glass microspheres simulating afterload will stimulate the secretion of angiogenic factors. Hence, we employed glass microspheres (average diameter 15.7 microm, average mass 5.2 ng) as a new method for imposing mechanical load on neonatal rat ventricular myocytes ...

Current technology relies heavily on composite materials, but in most cases, the size of the individual components have been micrometers or larger. The development of nanotechnology is driven in part by the desire to prepare materials that are only a few nanometers in size or that are made from components in the sub-micrometer regime. Improved preparations of various examples of monodisperse, p...

A solvothermal method was developed to prepare on a large scale monodisperse porous β-Co(OH)(2) microspheres consisting of nanoplatelets. Co(3)O(4) microspheres with porous platelets were obtained via subsequent thermal decomposition. These Co(3)O(4) microspheres show much higher ethanol sensitivity and selectivity at a relatively low temperature (135 °C) compared with those of commercial Co(3)...

The deposition behaviors of carboxylate-modified polystyrene latex microspheres (six sizes ranging from 0.1 to 2.0 microm) in packed porous media (soda-lime glass beads) were examined under a variety of environmentally relevant pore fluid velocities (4-8 m-day(-1)) in the presence of an energy barrier to deposition. Hyperexponential profiles of retained colloids were observed for all microspher...

Background: The innovative repair materials for the bones are still lacking. So, we synthesized a porous microsphere by using basic fibroblast growth factor (bFGF), polylactide-co-glycolide (PLGA), poly L-lactic acid (PLLA) and hydroxylapatite (HAP), and its biocompatibility with bone marrow mesenchymal stem cells (BM-MSCs) was investigated in vitro. Methods: A modified solvent extraction/evapo...

Nanoparticle coated microspheres are composed of two or more materials with a core/shell structure and exhibit unique abilities that allow amplification of trace targets in immunoassays. The preparation of nanoparticle coated microspheres can be accomplished using three main strategies: (1) in-situ, (2) ex-situ, and (3) hollow sphere methods. Antibodies or biomolecules can be immobilized on the...
