Our nanomaterial manufacturing technology belongs to the field of nanomaterials: it utilizes the nanotechnological effect that substances become especially "active" when their surface-volume ratio increases.

The innovation is based on laser ablation in liquids, which works without chemical precursors.

 

Due to its physical approach, laser ablation in liquids is generally different from chemical syntheses. Avoiding chemical precursors is useful for nanotechnology, as high purity is often required - for example in biological or medical applications or when a polymer is to be filled with nanoparticles without impurifying the matrix.

Nanoparticles from Particular offer the following advantages:

  • high purity of the colloids without left over precursors or byproducts,
  • economic production especially of nanoparticles from pure metals and alloys,
  • long durability due to electrostatic and optionally sterical stabilization,
  • organic solvents as possible direct dispersants without medium transfer.

Examples of unique applications enabled by Particular's method:

  • gold nanomarkers that are lasting and biocompatible (instead of bleaching fluorophores or toxic quantum dots),
  • nano-coatings from the same material as the workpiece to avoid additional material qualifications during product approvals,
  • volume embedding of metal nanoparticles in polymers for longer effectiveness than that of coatings (ion release capacities up to several years),
  • nanoparticle mixtures for coatings and volume embedding with adjustable function combinations.
