Ag nanoparticles were produced by the reduction of AgNO_3 with the protecting of sodium oleate using NaBH_4. After adding the transferring regent NaH_2PO_4, a film of Ag nanoparticles was formed at the interface of water/organic phase. The film could be transferred to a substrate such as glass. The mechanism of the transfer of the film was discussed. Quartz Crystal Microbalance (QCM) was also used to measure the transferred colloidal quantity for Ag nanoparticles.
