Mikrosphären

Microspheres usually consist of a spherical shell that is made of a biodegradable or resorbable plastic polymer, that has a very small diameter usually in the micrometer or nanometer range, and is often filled with a substance (such as a drug or antibody) for release as the shell is degraded. New miniaturised, high throughput technologies for bioseparation, diagnostics, DNA sequencing, flow cytometry, drug discovery, proteomics and genomics are in many instances reliant on attachment of functional biological molecules to a microsphere support.
