Schematic diagram of the absorption characteristics of eukaryotic and prokaryotic bio-smoke materials. (a) Absorbance of six bio-smoke materials in the infrared band (400–4000 cm^–1). (b) Analysis of infrared absorption peaks of various components of the bio-smoke materials. The absorption peaks of proteins and nucleic acids in the ultraviolet bands (purple parts) in the figure are derived from the literature.^[29]
