Silver nanoparticles (Ag) have properties that extend the range of application into photovoltaics and photonics due to unique optical properties, from inks to pastes and fillers for their excellent eletrical properties, to wound dressing and textile for their known antimicrobial activity.
We at Particular Materials synthesize nano Ag and we produce dispersions with excellent stability, monodispersity and fully disaggregated state.
Our silver nanoparticles portfolio currently consist of particles with diameters ranging from 15 to 28 nm and find applications in several industries.
Silver nanoparticles are increasingly applied for antimicrobial coatings, drugs and biomedical devices for protection against bacteria.
Furthermore, the interesting optical properties of silver nanoparticles are exploited as a functional component in various products and sensors. They are extraordinarily efficient in absorbing and dispersing light and, unlike many dyes and pigments, they have a color that depends on the size and shape of the particle.
In order to be able to take advantage of the various properties of Silver (Ag) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.
We at Particular Materials synthesize nano Ag and we produce dispersions with excellent stability, monodispersity, crystalline purity and fully disaggregated state.
The Ag nanoparticles are available in four different size:
- 15 nm
- 28 nm
Typical concentration in water are, by weight (w/w%):
Silver nanoparticles can also be provided as nanopowder.
Related Applications and Industries
• Biosensors and numerous assays where the silver nanoparticle materials can be used as biological tags for quantitative detection.
• Conductive inks and integrated into composites to enhance thermal and electrical conductivity.
• Can be mixed with zinc oxide powder for disinfection
• Ag is also used as a chemical catalyst
A peculiar characteristic of all nanoparticles is the high surface area to volume ratio, that allows a considerably higher binding capacity and excellent dispersibility of NPs in solutions.
