Single-use sensor strips detect cerebrospinal fluid leaks
Researchers developed a single-use sensor strip that can be used with a circuit board to detect cerebrospinal fluid leaks. They collected nine clinical samples and introduced the test fluid into a small liquid channel on the tip of the sensor strips. The liquid channel held electrodes, which contained antibodies specific to proteins found only in human cerebrospinal fluid. The circuit board analyzed the signal and produced a four-digit number that correlates to the concentration of the protein beta-2-transferrin, found in CSF.
