Under the Results subheading "Py-GCMS" the sentence reading "Analysis of the natural melanin sample produced a chromatogram containing mostly benzene, benzenenitrile, pyrrole and its methyl derivatives, phenol, phenol-4-methyl, styrene, indole and 3-methylindole (Fig. 6), comparable to previous studies [28,29]" should read: "Analysis of the natural melanin sample produced a chromatogram containing mostly benzene, benzenenitrile, pyrrole and its methyl derivatives, phenol, phenol-3-methyl, styrene, indole and 3-methylindole (Fig. 6), comparable to previous studies [28,29]."
