of the biomechanics in the foot, so will definitely improve foot pain. other companies are coming up with their solutions to the problem too. these look like a regular pair of heels, right? gait:tech also combines biomaterials and orthopaedic knowledge to develop insoles that can be put in at the point of manufacture. although they are not personalised, they too aim to redistribute pressure and better biomechanics. so the test is, how do they feel? the real benefits should be felt when you are wearing them for several hours, but i am going to give them a try now to see how they are when you first put them on. ok, the first thing i am very conscious of is there is a little bit more support at the back of my toes than i would normally feel. i thought they were going to support the arches more. that still feels normal. i still think the comfort of shoes is largely dependent on how soft the leather is around them. but perhaps what i have noticed now as that i am only walking
Tissue engineered constructs can serve as in vitro models for research and replacement of diseased or damaged tissue. As an emerging technology, 3D bioprinting enables tissue engineering through the ability to arrange biomaterials and cells in pre-ordered structures. Hydrogels, such as alginate (Alg), can be formulated as inks for 3D bioprinting. However, Alg has limited cell affinity and lacks the functional groups needed to promote cell growth. In contrast, graphene oxide (GO) can support numerous cell types and has been purported for use in regeneration of bone, neural and cardiac tissues. Here, GO was incorporated with 2% (w/w) Alg and 3% (w/w) gelatin (Gel) to improve 3D printability for extrusion-based 3D bioprinting at room temperature (RT; 25°C) and provide a 3D cellular support platform. GO was more uniformly distributed in the ink with our developed method over a wide concentration range (0.05%–0.5%, w/w) compared to previously reported GO containing bioink. Cell support w
