  1. What is a polymer? PolymersMany units Single units (monomers) Get connected to make… … a polymer chain!

  2. Do I know of any polymers? www.ziploc.com www.wiki.com

  3. Polymers & the Body www.avantgardeeyecare.com http://www.anaesthesiacases.com http://www.gentili.net Things like polymers are considered… …Biomaterials

  4. Biomaterialsare all around www.avantgardeeyecare.com www.lawilshireperio.com www.nebraskafootandankle.com www.dreamstime.com www.sciencemag.org www.shortwhitecoats.com

  5. Some Polymers swell in H2O We call them Hydrogelswater www.avantgardeeyecare.com http://kids.britannica.com Polymer chains join together to make a solid material that is filled with H2O. They are joined by… http://kids.britannica.com www.warrenfencecompany.com www.wiki.com

  6. Is alginate found in nature? www.wiki.com Plant Cell www.eaaroncohen.blogspot.com Ca+2 www.bio-world.com Brown Algae www.tolweb.com

  7. Need… • apolymer • way to join polymer chains • water • How to: • Get alginate (polymer) from heartburn tablets. Alginate has a -1 charge. • Use calcium (+2 charge) to join the alginate chains • Combine the two ingredients in water to make a your own hydrogels Could we make a hydrogel ourselves?

  8. Work in partners to make alginate hydrogels (start hands-on lab)

  9. Cutting edge hydrogels Control the release of medicine! www.intechopen.com IncreasingTemperature Heat sensitive hydrogels Grow cells for making new tissue! Light degradable hydrogels www.udel.edu

  10. Brainstorm! • Can you think of where in the body you can use hydrogels? • How about… • Bones? • Eyeball? • Skin?
