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...

The purpose of writing this review on Hollow microspheres is to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. Hollow microsphere promises to be a potential approach for gastric retention. The recent developments of FDDS including approaches to design single-unit and multiple-unit floating systems, mechanism of floating mi...

Thermostable heat-insulating composite materials based on solid magnesium phosphate and calcium binders, fly-ash glass hollow microspheres have been developed proposed. Thermal phase transformations studied as well strength characteristics of the initial composites products their thermal treatment up to 1000 °C determined. It is shown that prepared are thermally stable in temperature range 20 –...

In porous ceramics processing, the green body shaping technique largely determines control of final structure and material properties. The study is aimed at finding affordable approaches for two different narrow-fraction fillers: F240 electro-corundum hollow alumina microspheres. results revealed influence accessible techniques (semi-dry pressing, direct casting, slip casting) on structural mec...

Here, we report the novel application of a material with self-concentrating properties for enhancing the sensitivity of immunoassays. Termed as glass microbubbles, they are antibody functionalized buoyant hollow glass microspheres that simultaneously float and concentrate into a dense monolayer when dispensed in a liquid droplet. This self-concentrating charactaristic of the microbubbles allow ...

80% except for acetaminophen, due to its lower solubility in water and higher solubility in corn oil. The release profile of the drug was pH dependent. In acidic medium, the release rate was much slower, however, the drug was released quickly at pH 7.4. Tacrine showed unexpected release profiles, probably due to ionic interaction with polymer matrix and the shell structure and the highest relea...
