Stretching DNA on a chip

DNA carries all information a living organism requires for survival. Reading this information can be made much easier if you can get these 2nm wide polymer strand stretched and untangled. Researchers at Purdue University have done just that.



They have precisely placed strands of DNA on a silicon chip and then stretched out the strands so that their encoded information might be read more clearly. This may prove extremely critical in future electronic devices and computers.
