Up for aution is a vial of monodispersed polystyrene microspheres with nominal diameter of 2.8 micron in dry form 250 mg. They are prepared by emulsion polymerization and cleaned thoroughly by centrifugation. The dry powder can be dispensed in any solution of your choice by conventional mixing methods such as vortex or ultrasonication. Specifications: Particle Diameter: 2.8 um Matrix: Polystyrene Surface functionality: Plain Potential Applications of Microspheres (Referred to Microspheres in Wikipedia at https://en.wikipedia.org/wiki/Microsphere): New applications for microspheres are discovered every day, below are just a few: Assay - Coated microspheres provide measuring tool in biology and drug research Buoyancy - Hollow microspheres are used to decrease material density in plastics (glass and polymer) Particle image velocimetry - Solid microspheres used for flow visualization, typically with density matching that of the fluid.[5] Ceramics - Used to create porous ceramics used for filters (microspheres melt out during firing, Polyethylene Microspheres) or used to prepare highstrength lightweight cocnrete.[6] Cosmetics - Opaque microspheres used to hide wrinkles and give color, Clear microspheres provide "smooth ball bearing" texture during application (Polyethylene Microspheres) Deconvolution - Small fluorescent microspheres (<200 nanometers) are required to obtain an experimental Point spread function to characterise microscopes and perform image deconvolution Drug delivery - As miniature time release drug capsule made of, for example, polymers. A similar use is as outer shells of microbubble contrast agents used in contrast-enhanced ultrasound. Electronic paper - Dual Functional microspheres used in Gyricon electronic paper Insulation – expandable polymer microspheres are used for thermal insulation and sound dampening. Personal Care - Added to Scrubs as an exfoliating agent (Polyethylene Microspheres) Spacers - Used in LCD screens to provide a precision spacing between glass panels (glass) Standards - monodispere microspheres are used to calibrate particle sieves, and particle counting apparatus. Retroreflective - added on top of paint used on roads and signs to increase night visibility of road stripes and signs (glass) Thickening Agent - Added to paints and epoxies to modify viscosity and buoyancy Drugs can be formulated as HBS floating microsphere. Followings are list of drugs which can formulated as microsphere: Repaglinide, Cimetidine, Rosiglitazone, Nitrendipine, Acyclovir, Ranitidine HCl, Misoprostol, Metformin, Aceclofenac, Diltiazem, L-Dopa and beneseragide, Fluorouracil
