Researchers have made a biochip that could help replace animal testing for new cosmetics and pharmaceuticals.
Drug candidates that seem promising in preliminary laboratory tests often fail once they are tested for toxicity in animals--a waste of time and money for a pharmaceutical company. What's more, chemical and cosmetics companies are increasingly looking for cheap and efficient ways to test potential products for toxicity problems without resorting to animal testing. Now, researchers have designed a biochip that could screen out compounds with toxicity problems much earlier in the drug-development process. It could also be useful for rapidly screening chemicals and cosmetics for potential toxicity.
