Abstract
A method for universal contactless printing comprises depositing a first droplet into a sound field, curing the droplet to form a cured droplet, depositing a second droplet, and securing the second droplet to previously cured droplet by curing the second droplet. The method of contactless printing can be repeated to form a complex three-dimensional structure. The first droplet that is deposited can be secured to a moveable structure by curing the first droplet to the moveable structure. The moveable structure can be moved to place a next droplet to be deposited and cured.
Claims19
A method for encapsulating a drug comprising:
- suspending a liquid drug droplet containing one or more active ingredients in a sound field;
- injecting a biocompatible solution to surround the liquid drug droplet;
- curing the biocompatible solution to enclose the liquid drug droplet within a cured shell and form the drug;
- applying a liquid layer to the drug;
- and
- curing the liquid layer to create a multi layered drug or a shelled compartment around the drug.
