Nanoencapsulation entraps an active ingredient within a protective shell or matrix, creating a particle size or component (shell or heterogenous phase) that is less than 100 nm or 1 µm.
Southwest Research Institute (SwRI) uses multiple nanoencapsulation techniques to produce nanosized particles and capsules to address the performance needs of many applications.
Techniques & Capabilities
SwRI staff are experienced with a wide variety of nanoencapsulation techniques, including:
