Abstract

The unique characteristics of nanoscale materials make them a perfect fit for the sensor world. Integrating these materials into existing sensors can increase the sensitivity, selectivity and speed of the sensor—all of which could translate into enormous leaps in sensor performance. In addition, their high surface area and low volume provide a perfect setup for sensor miniaturization. Researchers at the Department of Energy’s Pacific Northwest National Laboratory are integrating functionalized nanoporous silica and carbon nanotubes—both nanoscale materials—into a variety of sensor applications to meet urgent needs in fields ranging from biomedicine and environmental remediation to national security. The scientists’ goal is to set the stage for developing a miniaturized sensor that uses the smallest sample possible to detect the smallest concentration possible of molecules of interest.
