The crucial factor for sufficient analysis by surface-enhanced Raman spectroscopy is the preparation of an effective SERS substrate with a surface of appropriate optical properties. This work focuses on the modification of surfaces of Al2O3 and cellulose impregnated by polyethyleneimine to increase the deposition effectiveness, size, and morphological characteristics of the deposited silver particles. Modifications of substrates were done by polydopamine layer formation on substrate surfaces or by surface activation through immersion in SnCl2 solution. The silver particle layers were done by deposition from a liquid phase using ultrasound-assisted reduction of silver ammonia complex ([Ag(NH3)2]+) by maltose or glucose which served as reductants. Prepared layers were in some cases subsequently recrystallized by NaCl solution which led to formation of the larger silver particles or aggregates. The morphologies of the prepared layers were characterized by SEM. The SERS efficiency of the presented substrates was tested through SERS measurements of 10-5 M adenine solution using lasers of 532 nm and 780 nm excitation wavelengths. The influence of substrate surface modification and re-crystallization of the silver particles on SERS efficiency was evaluated by enhancement factor calculations. Their values reached up to 1.4.106 for 780 nm and 8.1.105 for 532 nm lasers.
