Biochar is a made through a simple combustion method from any biomass. This research utilized biochar from 3 different biomass sources, as well as a green hydrothermal synthesis, to produce fluorescent carbon-based particles. Characterization of these particles were carried out using Infra-Red, Ultraviolet-Visible, Fluorescence, and Nuclear Magnetic Resonance spectroscopy. These particles are composed of a conjugated carbon lattice with nitrogen and multiple carbon-oxygen functional groups. The use of an economical and green synthesis that allows for the production of these oxidized particles with no waste or by-product, makes this compelling as a research focus. All 3 biochar-based carbon particles exhibit similar strong fluorescent behavior when excited by light in the ultra-violet to near visible range, with light emission occurring in the visible region over a range of approximately 300nm with an emission maximum in the 430-450nm region. The physical and fluorescence characteristics of these particles makes them an ideal candidate for future research into a safe, green, cost-effective biosensor.
