A4CELL develops New technology named SPAchip (Suspended Planar-Array Chips) offering you a perfect way to track living single cell. SPAchips are intracellular silicon microchips for monitoring extraordinarily small volumes as a single cell. SPAchip technology has reduced the planar array concept over one billion times !! SPAchip device can be easily internalized in living cells without affecting cell viability or inducing physiological changes. Microarray technology, but NOW in a living single cell.!
