The first time I saw the P4SPR I was amazed by its small footprint. This device really addresses the lack of accessibility and cost barrier of current SPR options for academic users.

Afin de caractériser une cible biologique pouvant interagir avec une molécule d'intérêt pharmacologique, l'utilisation de la SPR s'est avéré un choix judicieux.
L'interface est facile d'utilisation et accessible pour des scientifiques dont le domaine d'expertise se rapproche de près ou de loin à la physique des plasmons.

A number of academic research labs in the university have taken advantage of the ultra-portable unit to carry out SPR based binding experiments in their own labs with publishable results.

The flexibility and modularity of the system is key for us. We were able to adapt the P4SPR to integrate electrochemistry and fluorescence spectroscopy in parallel with SPR to create a unique multi-analytical system fitting our research needs.
