摘要：

Ultrasensitive surface-enhanced Raman scattering substrate of Ag nanoparticles was obtained by the mechanochemical reaction of copper foil and beta-silver vanadate nanoribbons. The substrate exhibited excellent sensitivity when the concentration of dopamine solution down to 1 x 10(-10) M and was successfully employed to detect the dopamine in a single mouse brain cell. This ultrasensitive substrate might be used as an in situ monitor in biomedical fields.
