General description

Silver trifluoroacetate is the silver salt of trifluoroacetic acid and appears as a light-yellow crystalline powder. Its excellent solubility in water, acetone, and ethanol makes it easy to handle in solution-based processes. It is often used as a silver source for creating thin films on electronic substrates via techniques like spin-coating, dip-coating, or spray-coating, forming conductive silver layers.

Application

Silver trifluoroacetate is used
  • As a precursor to synthesize ultrasmall icosahedral silver nanoparticles with precise size control and high monodispersed, ideal for advanced applications in plasmonic sensing, nanoelectronics, and biomedical diagnostics.
  • As a co-precursor to promote the formation of silver nanocluster nodes, enabling the controlled self-assembly of coordination polymers designed for advanced applications in optoelectronics and molecular sensing.
  • As a silver source to coat gold ultrathin nanorods with a single atomic silver layer, fine-tuning their optical properties for use in plasmonic sensing and nanophotonic.
  • As a bifunctional reagent and it serves as both a convenient in situ CO source and an oxidant in the reaction.

Features and Benefits

High silver loading (48.7%) increases the availability of active sites for catalysis, leading to more efficient conversion of reactants into products as more Silver atoms are involved in the reaction.

Protein coronas around silver nanocubes were quantified in serum-containing media using localized surface plasmon resonances. Both soft and hard coronas showed exposure-time and concentration-dependent changes in protein surface density with time-dependent hardening. We observed spatially dependent kinetics of the corona-formation
