BIOSENSOR Assay TechnologyBIOSENSOR Assay Technology

1. MIX Sample is mixed with sensing solution: Magnetic microspheres and fluorescent tag.

2. BIND Sensing materials bind spores during

mixing and incubation.

3. MAGNETIZE All bound and unbound magnetic

material separate to surface.

4.WASH Unbound TAG remains in solution

and is washed away.

5. READ Concentrated sample (pellet) is illuminated

and emits a signal if target is present.
