Why choose MP-SPR for electrochemical biosensor development?

Easy ex-situ modification of SPR sensor surfaces

MP-SPR instruments do not require refractive index oil and thanks to a fast locking holder for sensors, there is no need for two-sided tape either. Sensors can be functionalized in-situ with electrodeposition or ex-situ with a number of methods including spin-coating, dip coating, Langmuir Blodgett, ALD, sputtering, CVD, etc.

Reuse of our sensors is possible. Our gold sensors use a superior adhesion layer that allows for repeated cleaning with strong acids. We provide many other sensor surfaces including Cr, Al, Ag, Pt, and more.

Simultaneous recording of electrochemical and MP-SPR signals

In-situ combination of MP-SPR with electrochemical recording is possible thanks to a dedicated electrochemical flow-cell. Other flow-cells can be easily exchanged by the user. 

Compatible with most organic solvents

The electrochemical flow-cell as well as all of the instrument are built of materials that are resistant to most organic solvents. Beyond organic solvents, MP-SPR works also with gas and vapors. The samples can be purified or crude including sea water or serum. The sample can contain even metallic nanoparticles and still be measured by MP-SPR. Ask about the compatibility of your sample

Conformational changes in real-time

MP-SPR reveals changes at the surface, whether it is protein adsorption, thickness change due to swelling or change in optical properties of the layer. Currently, MP-SPR is the only SPR instrument in the market able to quantify also conformational changes using LayerSolver and measurements at multiple wavelengths.

No swelling artifacts

MP-SPR is an optical method and thus, the measurements are not hampered by liquid trapped in the interfacial layers. See why!
