After AGTC's presentation,
I think this field is too late for me to start, then already did part of it.
they identify active compounds in Chinese Herbs by using there HerboChip & HerboLink plate form.
they got several patents for it, ex: microarray on plastic, microarray using unknown probes, microarray using natural compounds as probes, etc.
But, they need target to start.

they proved it works, already have products, already have sale lines.
can scan 400000 compounds / human day.
