Core-Shell Structured Alginate Capsules for Encapsulation of Particles, Colloids and Cells

Summary

The method for preparing capsules, such as micro- and/or nano-capsules from all-aqueous emulsions. The method includes mixing, combining, or contacting a first electrically charged phase containing a first solute with at least an optionally charged second phase containing a second solute. The solutes are inompatible with each other. The electrostatic forces between the two solutions induce the formation of droplets of a dispersed pahse in a continuous phase. The droplets are then solidified to form the capsultes.

Technology Benefits

- Novel way to produce hydrogel capsules using electrospray technique
- Enable the encapsulation of living cell species
- The product has a liquid core and solid shell.
