Paper Abstract

Comparative optical study of biofluids (serum, urine, hemodialysate) and carbon nanodots (CND) aqueous solutions has been done. Biofluids were collected from chronic kidney diseases patients (CKD Pts) as well as from normal controls (NCs). Sugar derived CND and oxidized graphene solutions were prepared and used. Fluorescence and excitation spectra have mainly been measured and compared for two sets of subjects. For both family of subjects typical fluorescence with parameters λexсmax/ λemmax = 320±5/420±5 nm is observed and has many analogeous properties. New effective method of additional similarity identification with use of aluminum salts Al2 (SO4)3, Al (N03)3 and AlCl3 is proposed. Aluminum ions induce the fluorescence band at 380 nm in all substances investigated. Plenty of similar features (12) in optical properties create a united platform for further investigation of the topic - the nature of endogenous near UV and visible fluorescence in biofluids and CND.
