Application

Ethanol was used as dispersion medium for already prepared silver nanoparticles.
It may be used in the following studies:
  • Hydrothermal synthesis of single crystal ZnO nanorod.
  • Synthesis of N-(N′dodecylcarboxamidomethyl)N,N,dimethyl ammonio propane sulfonates.
  • As solvent for cytofluorimetric analysis.
  • Preparation of TiO2 colloid (particle size = 20nm).
