Description

Much of the prior art in the field of chemical sensing discloses the use of SWNT based sensors for detection of analytes. However, such sensors are not specific for detecting air borne chemicals. Moreover, other electrochemical sensors/technologies used for such detection procedures are limited by their larger size, lower sensitivity (not on micron scale), and narrow operation range (room temperature & pressure conditions only). This novel approach enables the development and use of chemical sensor arrays based on highly organized SWNT networks, overcoming many prior art limitations.

 

Value Proposition

The chemical sensor array:

•Is reusable

•Is highly sensitive (micron scale with ppm range) and selective as compared to conventional techniques

•Has a quick response time (seconds) as compared to conventional approaches

•Enables detection based on the conductance, as it works by measuring the drastic change in the current flowing through the SWNT channel as opposed to conventional electrochemical methods

•Enables in-situ detection of chemicals both in the hydrocarbon reservoir and in the gas stream at harsh conditions (up to 180C and 20Kpsi pressure)

•Is able to detect the hydrogen sulfide gas in various environments

•Serves as a platform for the development of multifunctional sensors
