Surface functionalized Microparticles

PolyAn’s high-performance polymer microparticles are functionalized with a 3D surface chemistry comprised of a long-chain polymer with a defined number of reactive groups. In contrast to conventional coating procedures, the reactive polymer is covalently linked to the surface.

By using MSE-technology, a thin polymer shell of a few nanometers, consisting of carboxyl groups, is formed on the surface. This occurs without changing the excellent physical and optical properties of the PMMA-core. Our 3D-Carboxy microparticles are suitable for EDC/EDAC mediated coupling of amine-containing molecules or for ionic interaction.

PolyAn offers the following surfaces for immobilization of DNA, peptides and proteins:

Unspecific binding and aggregation of biomolecules is reduced by our antifouling functionality. Our rigorous quality control procedures according to ISO 9001 ensure the constant loading and low batch-to-batch variation necessary for molecular diagnostics and pharma screening.
