Nanomedicine is the application of nanoscience and nanotechnology to health sciences. Nanoparticles can be used as carriers to deliver drugs specifically to the target area (e.g., cancerous tissues) and achieve sustained and controllable release. In this demo, we will introduce the process of forming “macro-capsules” and the concept of gradual release. Food coloring is used as the encapsulated material as well as a visual indicator of capsule formation, while alginate, chitosan and/or calcium ions are used to form cross-linked membranes. Two types of capsules with different mechanical strengths were prepared to demonstrate the concept of sustained release. Additional resources provided in this module will help you to further explore different variations of the encapsulation experiment.

NISENet: Exploring Fabrication - Gummy Capsules: How can things build themselves?
"Exploring Fabrication - Gummy Capsules" lets visitors make self-assembled polymer spheres. They learn that self-assembly is a process by which molecules and cells form themselves into functional structures, and that self-assembly is used to make nanocapsules that can deliver medication.
Resources to be added after the demo.
