• General description

  Lee-Meisel method has been proposed for the preparation of silver colloids for surface-enhanced Raman scattering (SERS), via AgNO₃ reduction with sodium citrate. It has been reported as an antagonist of ethylene. Its effect on the plant regeneration of callus cultures of Zea mays has been studied.

  Application

  Silver nitrate may be employed as stain to study the osteogenic differentiation of fetal human mesenchymal stem/progenitor cells (MSCs). It may be used in the preparation of highly sensitive silver colloids for surface-enhanced Raman scattering (SERS) studies.
