Computational Spectroscopy of Structured Carbon Nanotube Interfaces for Biochemical Sensing

Abstract

Compressive measurement in spectroscopic and interferometric systems has been demonstrated. Computational spectroscopy studies resulted in the development of the coded aperture snapshot spectral imager (CASSI) and coherence measurement studies resulted in the development of compressive holography. We developed the theoretical underpinnings of coded aperture snapshot spectral imaging and designed two proof-of-concept systems: a pushbroom system (SmacM) and a snapshot system (MacSim). Isolated growth of nanoscale carbon nanotube (CNT) islands has been accomplished as well as growth via a Pt catalyst, including microstructural validation of the CNT structure using transmission electron microscopy. The use of Pt catalyst during the CNT growth rather than the more traditional CNT catalyst materials is beneficial due to the extensive study of SERS (Surface Enhanced Raman Spectroscopy) and new biological application areas are enabled due to Pt's approved use for in-vivo applications.
