Carbon nano-onions (CNOs) are spherical, multilayered, onion-like carbon nanostructures. The purpose of this project was to understand the relationship between surface functionalization and fluorescence intensity of carbon nano-onions for bioimaging applications. Functionalization of CNOs was executed by adding carboxylic acid groups to the surface via a strong acid synthesis. CNOs were characterized using Fourier transform infrared spectroscopy, Raman spectroscopy, transmission electron microscopy, and thermogravimetric analysis. The fluorescence emissions of the functionalized CNOs were analyzed by using a fluorescence microscope to gather fluorescence images under various excitation wavelengths. The use of fluorescein, a fluorescent tag, was also investigated by attaching the tags to the functional groups on the CNOs and analyzing their fluorescence emissions compared to carboxylic acid functionalized CNOs and pure CNOs.
