      abstract     = {Surface-enhanced Raman scattering (SERS) is a highly
                      advantageous analytical technique for detecting trace
                      biological and chemical compounds. However, significant
                      challenges remain in the cost-effective fabrication of
                      large-area and homogenous SERS substrates. A simple and
                      scalable approach utilizing a layer-by-layer spray
                      deposition followed by thermal annealing is proposed to
                      fabricate cellulose nanofibril (CNF) films loaded with gold
                      nanoparticles (Au NPs) and graphene oxide (GO) hybrids as
                      SERS substrates. These hybrid 3D structures comprising
                      CNF/Au NPs/GO significantly enhance SERS sensitivity by both
                      electromagnetic enhancement and chemical enhancement.
                      Incorporating CNF as a 3D network enables a more uniform
                      distribution of Au NPs/GO. Thermal annealing further induces
                      hotspots. For instance, the annealed CNF/Au NPs/GO hybrid
                      thin films achieve a detection limit of 1.0 × 10$^{−13}$
                      m and a high enhancement factor of 4.97 × 1011 for
                      Rhodamine 6G. Grazing incidence small-angle X-ray scattering
                      combined with nano-Fourier-transform infrared spectroscopy
                      is first used to confirm the combined Raman enhancement
                      mechanism of localized surface plasmon resonance and
                      interface charge transfer with high spatial resolution.
                      Therefore, the proposed methodology establishes a robust
                      framework for the scalable fabrication of ultrasensitive
                      SERS substrates.},
