All microfluidic elements and functions are integrated in a toolbox approach in the spinit® discs. biosurfit explores advanced proprietary microfluidics to perform all the required steps for any diagnostic test: allowing samples to be prepared, suspended or modified as required, resuspension of reagents, aliquoting, mixing and fluid delivery to detection areas. This is all integrated inside a plastic DVD-like disc and operated by a simple rotation protocol using a standard DVD drive.

The spinit® system combines three different methods, that currently cover the vast majority of blood analysis.

Immunoassays are performed with Surface Plasmon Resonance detection, using a polarised laser beam focused on the detection spots. The resonance of the light, detected by a phototransistor is altered by the presence of any molecules bound to the antibodies and this change 

(or SPR shift) quantifies the amount of protein present in the patient’s blood.Automated cytology is performed using an integrated microscopy module, specific microfluidic structures and standard haematology dyes.

Clinical chemistry assays are performed by measuring the absorbance of light at different wave lengths using multiple LEDs.
