Especially for diagnostic applications PolyAn is offering a broad range of functionalized microarray polymer slides. For reasons of reliability and bio-safety, patient-centric biomarker testing is always performed in single-use cartridges with a one-step process (sample in – result out). These cartridges should be disposable after use, so the materials of the cartridge should be non-hazardous and recyclable.
PolyAn's Polymer Slides are comprised of a low auto fluorescence plastic. The material is highly robust against breakage making it the material of choice when working with hazardous materials. It is suitable for injection molding and hot embossing processes.
The slides are produced with standard dimensions of 25 x 75 x 1 mm. Additionally, we offer the functionalization of your plastic including microfluidics with a surface modification that is tailored to your specific application. Please also have a look at our ProPlate, HybriWell and SecureSeal products that facilitate handling of slides.
3D-Amino Polymer Slide, 25 slides/box

3D-Aldehyde Polymer Slide, 25 slides/box
104 00 351
3D-NHS Polymer Slide, 25 slides/box
104 00 451
PolyAn's 3D-NHS functionalized slides are used for covalent immobilization of biomolecules. The NHS-ester react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface.
3D-Activated Amino (PDITC) Polymer Slide, 25 slides/box
104 00 481
PDITC (1,4-phenylenediiso-thiocyanate) activated amino groups react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface (420 kJ/mol).
3D-Thiol Polymer Slide, 25 slides/box
104 00 551
Covalently coated Poly-L-Lysin Polymer Slide, 25 slides/box
104 01 251
Poly-L-Lysin surfaces are well suited for coupling of biochemical species. Especially, when the storage buffer contains glycerol Poly-L-Lysin surfaces are an interesting alternative to reactive matrices.
3D-Maleimid Polymer Slide, 25 slides/box
104 01 441
Maleimide-surfaces for „click chemistry“ for oriented covalent coupling (immobilization) of thiolated biochemical species.
Covalently coated Streptavidin Polymer Slide, 25 slides/box
104 02 255
Covalently coated Neutravidin Polymer Slide, 25 slides/box
104 03 255
Covalently coated Avidin Polymer Slide, 25 slides/box

PolyAn’s 3D-functionalised microarray Slides are functionalized with a three-dimensional (3D)-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.|
hydrophilicity / hydrophobicity (contact angle).
|Uniform spot morphology||Narrow variation of surface properties and homogeneous distribution of reactive groups.|
|Optimal density and high accessibility of reactive groups||Morphology and thickness of functional layer tailored to the desired application.|
The slides are packaged in inert atmospheric boxes, with a capacity of 25 or 5 slides per box.
PolyAn’s slides are characterised by a long shelf-life when stored dry, at 4-8°C and protected from sunlight. All slides are packaged in boxes under Argon atmosphere to avoid contamination with particles. The Argon atmosphere also minimises degradation of the reactive surface through contact with air or humidity.
