SERS mapping result of R6G at 611 cm− 1 extracted from 1 × 10− 6 M aqueous solutions (a,b) and from 1 × 10− 9 M aqueous solutions (c,d). RSD for aqueous solutions of rhodamine 6G (R6G; 1 × 10− 6 M and 1 × 10− 9 M) were 2.49% and 10.95%, respectively. SERS spectra of R6G obtained by varying the concentration of R6G (front to back: 10− 9, 10− 8, 10− 7, 10− 6, 10− 5 M) on the nanohybridized paper substrate (e). Relationship between the intensity of the band at 610 cm− 1 and the log concentration of R6G. Inset: linear equation, LOD, and LOQ (f)
