a Raman shift spectra of bulk As and As/AsxOy NSs. b XRD spectra of bulk As and As/AsxOy NSs. c XPS spectra of bulk As, As/AsxOy NSs, and As/AsxOy@PDA@M NSs. d HRXPS spectra of As 3d in bulk As and As/AsxOy NSs. e HRXPS spectra of O 1s in bulk As and As/AsxOy NSs. f ESR spectra of bulk As and As/AsxOy NSs. For these chemical characterizations of fabricated As based NSs, three times each experiment was repeated independently with similar results.
