Recognition selectivity of dex-WS2 to different strains of E. coli. a Raman images of the dex-WS2-treated bacteria based on the 2LA(M) peak of dex-WS2 at 352 cm−1, showing the effective recognition of E. coli O157:H7 against E. coli K-12 and E. coli O1:K1:H7. b The normalized total intensity of the 2LA(M) Raman signal of dex-WS2 bound on three different strains of E. coli. All error bars represent a standard deviation from the mean values (n = 4)
