Nanosensors Could Help Reduce Laboratory Animal Testing

This idea is decades old -- testing substances in tissue culture. The Frauenhofer guys have come up with an interesting improvement.

It will never replace most of the animal testing.

Researchers do tissue culture testing all the time. Then after the tissue culture tests, they have to see if it still works in the rats. Lots of times it doesn't. That's especially true with cancer treatments. There are lots of pathways in real animals, and they interfere with each other, particularly liver enzymes.

We cured cancer in tissue culture many times. Then they try to repeat it in animals and it doesn't work.

And lots of animal testing has nothing to do with activating a receptor. How can you send a tissue culture through a maze?
This is especially a problem for discovering harmful effects of consumer products.
