Dr. Katherine Mirica of Dartmouth College will present her entitled:

Reinventing the Pencil: Mechanical Drawing of Gas Sensors on Paper and Plastic

Portable gas sensors are a critical part of managing and protecting the environment, human health, safety, and quality of life. Nanostructured materials, such as carbon nanotubes (CNTs), graphene, and two-dimensional conductive metal organic frameworks (MOFs), are an emerging materials with utility in chemical sensing.  A useful feature of these materials is that their electrical conductance can be extremely sensitive to changes in the local chemical environment.  This presentation will describe an exceedingly simple and rapid procedure, completely analogous to drawing with a pencil, for fabricating selective chemiresistors from CNTs and MOFs on the surface of paper and plastic.  The simplicity of this fabrication method enabled the discovery of several novel formulations for selective gas and vapor sensors, and made it possible to integrate these materials into low-power sensors, including wireless chemical sensing devices that can be interrogated with a smartphone using radio frequency communication.  Taken together, these developments may enable chemical sensors with broad utility in environmental monitoring, diagnosis of disease, and protection of public safety.
