Motivations for Using Biodegradable Microspheres in Drug Delivery

In recent years there is significant interest in using biodegradable polymeric microspheres for drug delivery. Delivering drugs through biodegradable microspheres has numerous advantages compared to conventional delivery systems. While in conventional systems the drug is usually released shortly after delivery and stops working after a brief period of time, biodegradable polymer offers a way to provide sustained release over…

Porous Ceramics: Application for Polyethylene Microspheres

Polymer microspheres offer an excellent solution to creating precise pore sizes in ceramics at reasonable prices. Polyethylene microspheres offer the added benefit of minimal residue after firing, and the availability in wide size ranges from a few micron up to 1000um (1mm). Highly spherical microspheres have the added benefit of creating strong pores without any…

Microspheres for Coatings Applications (Opaque Polyethylene)

Microspheres are well known in the coatings industry for their use as low-surface-area fillers that offer benefits in viscosity and density control, solids content, application and flow characteristics. Cospheric LLC, a Santa Barbara-based microtechnology company, recently launched a line of opaque polyethylene microspheres that act as a superior opacifying agent and provide maximum hiding power with just one monolayer…
