摘要/Abstract

摘要： The paper employs the principles of graph theory in nanobiophotonics, where the soot-assisted intra-pigmental energy transport in leaves is unveiled through the laser-induced thermal lens (TL) technique. Nanofluids with different soot concentrations are sprayed over Lablab purpureus (L) sweet leaves, and the extracted pigments are analyzed. The graph features of the constructed complex network from the TL signal of the samples are analyzed to understand their variations with optical absorbance. Besides revealing the presence of optimum soot concentration that can enhance photosynthesis, the study brings out the potential application of graph features in nanobiophotonics.
