Antioxidant activity of SeO decorated self-assembled nanotubes of 3,5-bis-trifluromethyl benzylamine derivative of phenylalanine electrochemical activity and its DFT studies

Abstract

In the current work, selenium oxide (SeO) which functions as an antioxidant in plants is studied and compared with self-assembled nanotubes of 3,5-bis-trifluoromethyl benzylamine derivative of single amino acid phenylalanine nanotubes (BPPNTs) decorated/intercalated SeO nanocomposites. Structural characterizations were done by UV, FT-IR, P-XRD, HR-TEM, Raman, and electrochemical studies. This study is conducted to determine the potential of BPPNTs-SeO composite against the radical formations through in-vitro tests like hydrogen peroxide(H2O2) and 2,2-Diphenyl-1-picrylhydroxyl (DPPH) free radical scavenging assay. The Impacts of covalent fictionalization of BPPNTs-SeO nanocomposites and their geometric and electronic properties are examined by the first-principles calculations. Energy of interaction and the charge distribution of the functionalized BPPNTs with the SeO are used to explain the antioxidant potential of the reported nanocomposite.
