Metal sensor slides
Metal sensor slides contains glass substrate coated with a metal layer. Use metal sensors as they are or functionalize them ex situ. suitable methods include: spin-coating, atomic layer deposition (ALD), chemical vapour deposition (CVD), Langmuir-Blodgett (LB).
Gold sensor slides
Gold (Au) sensor slides provide a versatile platform and are typically used for biosensor development, thin film characterization and cell studies.
The surface is highly stable which makes it the most widely used metal sensor. Typically, gold sensor slides can be cleaned using ammonium hydrogen peroxide wash or in UV-ozone chamber and re-used multiple times.

Custom inorganic sensor
Sensors for biomolecular interactions
A wide range of functionalized sensors is available for life science research and biosensor development. Select the surface depending on the functional groups of the ligand such as amine, thiol, biotin or histidine. Optimize also the surface binding capacity depending on the size of the analyte molecules such as small molecules, antibodies, viruses or nanoparticles.
3D carboxymethyl dextran sensors CMD-3D
3D carboxymethyl dextran sensors coated with dextran hydrogel layer of low, medium or high density. Medium density (3DM) is recommended for most biological assays like protein-small molecule or protein-protein interactions.
NID sensors
NID sensors are Ni chelator modified carboxymethyl dextran surfaces which allows capturing of His6-tagged ligand on a sensor. Binding is reversible and ligand can be removed. Tens up to hundred regenerations can be carried out.
Planar carboxymethyl dextran CMD-2D
Planar carboxymethyl dextran coating (less than 5 nm) allowing immobilization of ligands in a single monolayer. Much lower binding capacity surface as compared to CMD-3D sensors, recommended for binding of high molecular weight analytes such as antibodies or nanoparticles.
Biotin sensors
Biotin functionalized sensor slides: 2D monolayer (PEG) or medium density 3D CMD hydrogel.
BioNavis dextran like sensors BND
The BND sensor allows higher ligand binding capacity and lower non-specific binding compared to planar carboxymethyl dextran sensors. The BND sensors allow similar chemistry and protocols to be used as CMD sensors.
Streptavidin sensors
Streptavidin functionalized sensor slides: Streptavidin covalently immobilized on a CMD-2D sensor. CMD-3D sensor available on request.
Unique Regenerable Avidin – Kit
Biotinylated sensor slide functionalized with the newest technology!
Revolutionizing regenerable avidin kit allows reversible binding of biotinylated ligands and thus same sensor slide can be used to measure interaction of multiple ligand molecules.
Biotinylation enables control of ligand orientation on the surface for interaction measurement. Surface is planar with moderate binding capacity. Avidin and thus biotinylated ligand can be removed from the surface using regeneration solution included in the kit. This means that the same sensor slide can be used not only for several analyte molecules but also for several ligand molecules. Kit contains reagents enough for 80 complete cycles of regeneration. Possibility to regenerate the surface allows longer unattended runs and reduces consumable costs.
Contents of the kit:
- 2 sensor slides
- regeneration solutions for mild and complete regeneration (Reg. 1 and 2)
- regenerable avidin
