Abstract

Using high-intensity ultrasound, we have developed a method for the synthesis of magnetic microspheres. The microspheres are composed of iron oxide-filled and coated globular bovine serum albumin (BSA). The magnetic microspheres are prepared from BSA and iron pentacarbonyl, or from BSA and iron acetate. Transmission electron microscopy and scanning electron microscopy show spherical particles. The particle size distributions are gaussian, with a mean diameter of a few micrometers. Using chemical analysis, it was found that the total percentage of iron oxide in the microspheres is between 39% and 42%. Mössbauer measurements were also performed.
