In this thesis, we introduce approaches to carbon nanotube-based sensing for applications in environmental monitoring, disease diagnostics, and food analysis: In Chapter 1, we introduce carbon nanotube-based sensing. We describe parameters that give rise to the sensing capabilities of CNT-based sensors and discuss important performance parameters of carbon nanotube sensors. In Chapter 2, we demonstrate voltage-activated sensing of carbon monoxide using a sensor comprising iron porphyrin and functionalized single walled carbon nanotubes (F-SWCNTs). Modulation of the gate voltage offers a predicted extra dimension for sensing. Specifically, the sensors show significant increase in sensitivity toward CO when negative gate voltage is applied. In Chapter 3, we describe the design of a sensor for the highly selective detection of acrylates using conditions for the aerobic oxidative Heck reaction. The sensors mirror the catalytic processes and selectively respond to electron deficient alkenes by adapting a catalytic reaction system to modulate the doping levels in carbon nanotubes. In Chapter 4, we introduce sensor arrays consisting of imidazolium-based ILs with different substituents and counterions to provide selective responses for known biomarkers of infectious diseases of the lungs. In Chapter 5, we discuss a sensor array comprised of platform 20 functionalized SWCNT sensing channels for the classification of cheese, liquor, and edible oil samples based on their odor. We classify unknown food samples using a k-nearest neighbors model and a random forest model trained on extracted features. This protocol allows us to accurately differentiate between five cheese and five liquor samples (91% and 78% respectively) and only slightly lower (73%) accuracy for five edible oils.

The primary objective of this research is to examine the feasibility of using vertically aligned multi-wall carbon nanotubes (MWCNTs) as a high temperature sensor material for fossil energy systems where reducing atmospheres are present. In the initial period of research, we fabricated capacitive sensors for hydrogen sensing using vertically aligned MWCNTs. We found that CNT itself is not sensitive to hydrogen. Moreover, with the help of Pd electrodes, hydrogen sensors based on CNTs are very sensitive and fast responsive. However, the Pd-based sensors can not withstand high temperature (T

Optical biosensors based on fluorescent single-walled carbon nanotubes (SWNT) are a promising alternative to conventional biosensors due to the exceptional photophysical properties of SWNT. Such sensors can enable highly-sensitive, selective, and real-time detection of biological analytes. However, important questions regarding sensor fabrication and reproducibility must be addressed for these sensors to be of practical value. Herein we describe the use of highly-purified, single-chirality SWNT which are functionalized for antibody detection, and demonstrate that reproducibility is drastically improved with these SWNT. Further, we observe a concentration dependence of the effective equilibrium dissociation constant, KD,eff, which is in good agreement with previous reports, yet has eluded mechanistic description due to complexities associated with multivalent interactions. We show that a bivalent binding mechanism is able to describe this concentration dependence of KD,eff which varies from 100 pM to 1 uM for IgG concentrations from 1 ng/ml to 100 ug/ml, respectively. The mechanism is shown to describe the unusual concentration-dependent scaling demonstrated by other sensor platforms in the literature, and a comparison is made between resulting parameters. The platform is then extended to the detection of human growth hormone (hGH) using SWNT functionalized with a native hGH receptor (hGH-R), with potential use as a real-time and label-free measurement of protein activity. Native hGH is detected in the micromolar range, and an invariant equilibrium dissociation constant of 9 uM is revealed upon fitting the calibration curve to a single-site adsorption model. Selective detection of native hGH over thermally denatured hGH is shown at a concentration which is 1% of a clinical dose. Lastly, a multichannel detector was built to demonstrate real-time characterization of multiple protein properties. This work could find broad impact in biomanufacturing as real-time analysis of complex biologics is a long-standing goal in this field.
