Labs are furiously competing to perfect next-generation biochips, postage-stamp-sized devices that would track many proteins in a single step. But making them is vastly more complicated than creating DNA chips, popular research tools for analyzing suites of genes involved in everything from cancer to normal cell development. Despite the difficulty, a handful of academic groups and adventurous companies, from small start-ups to research powerhouses, are pursuing the technology.
