Abstract:
Paper-based surface-enhanced Raman substrate with reproducible signal is difficult to fabricate due to irregular hot spot produced by surface roughness and interfiber contact. Herein, we improved the surface uniformity of the filter paper by coating with bacterial cellulose nanocrystal (BCNC). The BCNC colloid smoothes the surface by forming film upon drying while filling the gap between fibers. Quasi-spherical gold nanoparticles (AuQNPs) was synthesized on the surface of BCNC film. Colloidal gold nanoparticles (AuNPs) was deposited on the BCNC film. Then, AuQNPs were directly grown on AuNPs. The AuQNPs decorated BCNC-coated filter paper was used as SERS substrate. The performances of the substrate were evaluated by 4-aminothiophenol (4-ATP). The SERS map of C-S stretching at 1079 cm-1 exhibited uniform signals across the sampling area with percent RSD of -9 percent. The lowest concentration of 4-ATP that can be detected was 1 nM. This disposable, reproducible, highly stable, easy to use, and low cost substrate has potential for screening applications.
