The chip is just one centimetre in size and could identify as many as 40 different genes. Huang Xinhua, an executive with Shanghai Boxing Gene Chip Corporation, the chip maker, said the chip could screen out transgenic soybeans, corn, cotton, rapeseed and other products, reported the Xinhua News Agency.
The chip could also proceed to inform the user whether the GM product had been cleared for entry into China. It is already being used by inspection and quarantine officials in south China, the report continues.
