Nano chip aims to test cells at molecular level in real time
Seven researchers are tapping nanotechnology to deliver a device that could some day conduct as many as many as 2,000 tests on individual biological cells in real time. The so-called nanolab chip could leapfrog today's gene and protein microarrays to create a much faster and more granular device than exists today for early diagnosis and drug screening. The chip uses microfludics to transport individual cells across the device, nanowire sensors less than 10 nm in diameter to identify genes and proteins in the cell and nanomechanical sensors to detect protein and gene interactions.
