Average Raman spectra of samples under different periodontal conditions. A Ramen spectra of serum samples: Peaks from left to right: 996- phenylalanine [39], 1146- carbon–carbon bonding modes from lipids [43], 1255- amide III [43], 1324- guanine, adenine [41], 1437- collagen, 1507- carotenoids [44], 1595- cytosine, 1646- amide I band, and 2916- lipid methyl or methylene stretch [44]; B Raman spectra of saliva samples: Peaks from left to right: 747- hemoglobin, 752- hemoglobin, 996- phenylalanine, 1041- glycated protein [44], 1118- carbon–carbon bonding modes stretch from lipids [43], 1300- fatty acids, 1328- guanine, adenine [41], 1332- phenylalanine, 1439- collagen, 1539- carotenoids, 1541- carotenoids, 1573- protein, 1597- cytosine [44], 1652- amide I band [40] and 2920- lipid [44]
