Stitching together 'lab-on-a-chip' devices with cotton thread and sewing needles

Scientists are reporting the first use of ordinary cotton thread and sewing needles to literally stitch together a microfluidic analytical device -- microscopic technology that can transport fluids for medical tests and other purposes in a lab-on-a-chip. The chips shrink room-sized diagnostic testing equipment down to the size of a postage stamp, and promise revolutionary applications in medicine, environmental sensing, and other areas.
