Key Features

Core Technology

The P4SPR uses benchmark Kretschmann configuration. The total internal reflection setup enables detection in complex media such as serum, milk or waste water. 

Flexible Design

The chip-based P4SPR requires users to inject various solutions to get real-time data. The three-channel sample port provides high-quality data that can be referenced by the fourth channel. For flow sensitive experiments, the P4SPR can easily be fitted to a pump or put inline with another instrument. See our Spec sheet to learn more.

Rapid Data Processing

The P4SPR Control™ software allows for easy data acquisition and processing of P4SPR data. The intuitive data processing method allows users to get a titration curve or affinity data in a very short amount of time.

MICROHOLE ARRAY SPR

Enhanced sensitivity with microhole arrays

The analytical technique surface plasmon resonance (SPR) is mainly defined by two classes of plasmonic materials: nanoparticles (mostly nanospheres) and thin films. Both classes exhibit nanometric physical features and present distinct optical characteristics fitting different applications. For instance, nanoparticles are the most sensitive materials but they cannot be deployed in complex media such biofluids (e.g., blood, serum, urine) for SPR measurements as the media will generate optical interferences.

Although less sensitive, thin films address all the complex media issue in addition to be easier to manufacture for large scale deployment in industry applications. Effort to combine the strength of both plasmonic materials into a single one have been driven by researchers. Most successful efforts started from the thin film end of the spectrum and moved towards integrating nanoparticle features to thin films.

Afficoat Surface Chemistry

Lower non-specific adsorption with Afficoat

The AffiCoat forms a protective self-assembled monolayer on metallic materials that significantly improves molecular recognition by minimizing non-specific adsorption. The proprietary heteropeptide sequence of AffiCoat has proven to be better than other broadly used anti-fouling chemistry such as Dextran, PEG-COOH and alkanethiols.
