N2 - In this paper, a successive ionic layer absorption and reaction (SILAR) process was reported for the first time to fabricate a low-cost, highly-sensitive and uniformed nanofibrillated cellulose paper (nanopaper) SERS device, through in situ growing silver nanoparticles (AgNPs) on nanopaper. The device demonstrates a picomolar-level limit of detection and an enhancement factor of 1.46 x 109. Raman mapping results show a superior spatial homogeneity of the device with a small standard deviation of ~14%. This nanopaper SERS device is a new SERS platform with high flexibility, excellent biodegradability, low cost, and ease of operation.
