This new tiny biomedical device makes diagnosing cancer types easier A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs. It can deliver colored stains to tissue samples accurately, so that scientists can view cancer cells under the microscope more easily.

A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs! This paper, published in the Journal of Biomedical Microdevices, represents a step forward in lab technology. Creating a tiny valve like this could have important implications for cancer research, where fluids…
