Surface Functionalization with Biomolecules

We offer surface functionalization of beads with biomolecules. Our extensive experience comprises covalently linking bio-molecules (DNA, oligonucleotides, peptides, proteins, enzymes, antibodies) to cationic or anionic surfaces as well as physical adsorption of these molecules to suitable LbL treated surfaces.

The main problems in particle chemistry such as unspecific binding, leaching, aggregation, or a significant reduction of the bio-activity are well known to us and can be mostly avoided by selecting the most suitable surface and coupling procedure.
