This is great! If we could do away with animal trials, that'd be one fat plus in our "good deed as a species" list. Only we must be 100% sure that this new technology works, and not just on paper but is completely fool-proof and failsafe. It's a complex piece of tech so there's many points where human error can creep in, potentially throwing off results. Wouldn't trust the safety of medicine on tech that could throw false negatives due to poorly cleaned lab vials or something.
