The future?
I attended a lecture at University of Westminster dealing with micro array technology with regards to Chemical Pathology in 1999 or 2000. At the time it seemed very promising. The lecture was performed by an academic but the underlying technology implementation was from Roche. It seems that this approach was subsequently mothballed. At the time, I heard it was for commercial reasons, as Roche were pushing a different immunoanalyser.
It now seems that Roche are back in the game…
