The self-healing and elasticity of this gel is pretty amazing. I would have liked to have this as a commercialized option for my dog who in the last two years went through two separate surgeries to repair the doggie equivalent of a torn ACL.
What's amazing to me about these hydrogels is their damage tolerance. The ability to stretch a polymeric material many times its original length is not all that noteworthy, but the ability to stretch a polymeric material with a notch in it many times its original length is totally incredible.
Understanding the mechanisms behind the toughness and damage tolerance of these hydrogels could lead to the development of tough polymers for all kinds of applications.
With regard to cartilage replacement, biocompatibility may be a hurdle. One of the biggest difficulties with cartilage replacement therapies to date has been the body rejecting the new cartilage (even when it has been grown in the lab from the patient's own cells).
Dave, I agree. I found the technical discussion a bit dense, but the ability to stretch and recover, notch or no notch, is apparently due to a mix of strong and weak molecular integration and the (resulting?) crosslinked networks.
This is amazing and sorely needed. For some young patients who have had a lot of cartilage removed, the only other alternative to is to use cadaver cartilage or an artificial knee. One of my college-age sons is now in this situation. If there was an artificial alternative that wouldn't be rejected by the body, it would be a godsend.
Ann, that's a new and interesting technology. Most of the old peoples have severe pain in their knees due to the wear and tear in cartilages around and beneath the knee cap. Any idea how we can apply this to the knee.
Charles, now there are some magnetic therapy treatments are available for regeneration of cartilages. I know some of the patient who had undergone the treatment and feels better. But so far it is not proved or accepted by any medical council.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
