Unlocking biological secrets: Cornell scientists build 'nano-keys' to bind cell receptors and trigger allergic reactions

The tumblers of life continue to click as Cornell University researchers have fabricated a set of "nano-keys" on the molecular scale to interact with receptors on cell membranes and trigger larger-scale responses within cells -- such as the release of histamines in an allergic response. How cell membranes control cellular function has long been studied but with ambiguous results. However, nanotechnology now gives researchers new tools to understand the role of cell membranes in activating responses within cells. Barbara Baird, Cornell professor of chemistry and chemical biology, reported this research today (Feb.16) at the annual meeting of the American Association for the Advancement of Science. She is the director of Cornell's Nanobiotechnology Center, which is funded by the National Science Foundation.
