Abstract

Chemical detection technology has been used in a variety of applications including disease diagnostics, bio-security, environmental monitoring, and food product recognition. Nowadays, the demand for a portable or decentralized sensing platform is rapidly increasing with the need for on-site target detection and analysis. Even though highly sensitive detection systems like gas chromatography/mass spectrometer (GC/MS) and ion mobility spectrometer (IMS) are currently available, such systems are bulky, expensive, and require time-consuming procedures. Ideally, next generation chemical sensing platform should have the following features: 1) highly sensitive and selective sensing; 2) rapid multiple target detection; and 3) a deployable, low cost, miniature, and robust system. The sensor system design based on emerging nano-bio-information technologies has the promise of satisfying these conditions.

I am developing a portable chemical sensing platform which integrates nanomechanical sensor array, bio receptors, and electronics. In this talk, various scientific and engineering aspects of the nanomechanical chem-bio sensor platform development will be discussed in detail.
