Method for detecting heavy metal ions based on ratio-type SERS (surface enhanced Raman scattering) sensing principle

The invention provides a method for detecting heavy metal ions based on a ratio-type SERS (surface enhanced Raman scattering) sensing principle. The method comprises the following steps: by taking silver coated with gold nano-particles as an SERS substrate, modifying T-rich sequences of Raman beacon...
