Multifunctional, self-sensing microcantilever arrays for unattended detection of chemicals, explosives, and biological agents

摘要

Unattended sensing applications necessitate robust, compact, low-cost, low-power sensor units. The microcantilever-based Self-Sensing Array (SSA) technology developed by Nevada Nanotech Systems, Inc. (NNTS) is a strong candidate for such units. SSA technology is expected to provide the selectivity, sensitivity, durability, low cost, and low power needed for unattended sensors and sensor networks. The sensor employs a variety of sensor coatings and the ability to analyze the electrical and thermal properties of molecules on the cantilevers. This so-called Lab-on-a-Tip™ technology could lead to enhanced chemical identification capabilities of the trace detection platform.
