Nanoencapsulation

HOW CAN WE HELP YOU?

Nanocapsules can be used in combination with other microencapsulation methods to provide new release characteristics. Our scientists work extensively with a number of nanoencapsulation techniques to produce nanosized particles and capsules that address the high performance needs of many applications.

Nanoencapsulation Techniques

SwRI staff routinely use the following nanoencapsulation techniques:

  • Micelles
  • Liposomes and polymersomes
  • Phase inversion/precipitation
  • Solvent evaporation
  • Polyelectrolyte complexes
  • Layer-by-layer deposition
  • Controlled precipitation
  • Surfactant-free particle formation
  • Templating
  • Molecular encapsulation

Nanoencapsulation Applications

  • Protein, DNA and RNA stabilization
  • Small molecule delivery
  • Extending circulatory half-life
  • Modifying drug transport
  • Clear liquid formulations
  • Stable colloid dispersions
  • Controlled release
  • Targeted delivery
  • Triggered release

Characteristics of Nanoencapsulation

  • Particle sizes from 10nm
  • Tunable colloid properties
  • Chemically functionalized surfaces
  • Hydrophobic or hydrophilic payloads
  • Low payloads
  • Organic or inorganic compositions
  • High surface area particles
