PolyAn offers a range of functionalized Microarray Slides for immobilization of biomolecules such as nucleic acids (DNA), peptides, proteins, saccharides. Our high-quality functional materials are used for miniaturization of high-throughput screening and production of biochips and new products for the biotech and pharmaceutical industries.
Additionally, we offer customized slides with a surface modifcation that is tailored to your specific application.
PolyAn’s Microarray Slides are functionalized with a 3-D surface chemistry comprised of a long-chain polymer containing a defined number of reactive groups. This polymer is covalently linked to the surface of the slide.
Our MSE-technology gently binds the functional layer onto the surface without damaging the base substrate. The morphology of the functional surface and thus also the number of the reactive groups can be fine tuned within a narrow range. This yields a number of advantages:
Low fluorescence background Covalent binding of functional layer on the substrate without changing the initial autofluorescence.
Low unspecific binding Combination of reactive functional groups with PolyAn antifouling matrix.
Surfaces for all biomolecules Tuneable surface hydrophilicity / hydrophobicity.
Uniform spot morphology Narrow variation of surface properties e.g. contact angle. Homogeneous distribution of reactive groups.
Optimal density and high accessibility of reactive groups Morphology and thickness of functional layer tailored to the application.
