The ResoSens bioassay system can help speed up your cell-based and biochemical assays by eliminating the need for chemical labels and labor-intensive processing.
The system utilizes 96-well and 384-well Bionetic microarray plates that are integrated with advanced label-free optical sensor technology.
The ResoSens system provides dynamic monitoring of binding interactions throughout your entire experiment (as shown in Figure 1) – not just endpoint data.
Our information-rich data provides kinetic binding profiles and the ability to customize your assay to reduce testing time and increase throughput.

Our innovative label-free approach is based on our proprietary guided-mode resonance sensor technology. High resolution monitoring of biochemical interactions are monitored using reflected light off the Bionetic microarray plate base. The surface of the Bionetic plate is nanostructured and designed to reflect a particular wavelength of light at a specific angle (Figure 2a). A wavelength shift occurs (Figure 2b) during the biochemical interaction – and the results are displayed in real-time on the screen.

produce resonance-peak shifts that can be tracked in real time.
