Use of borohydride solution for cleaning the platforms for the measurements of surface-enhanced Raman effect, containing a layer of gold

摘要

Use of a borohydride solution containing a borohydride compound (I), for cleaning a gold layer containing substrate, which is useful for measuring surface-enhanced Raman scattering, is claimed. Use of a borohydride solution containing a borohydride compound of formula (XBH 4) (I), for cleaning a gold layer containing substrate, which is useful for measuring surface-enhanced Raman scattering, is claimed.
