Engineers at Leeds University and Imperial College London have developed a load-bearing material that mimics human cartilage.
Researchers believe the new material could be used for a wide range of engineering purposes, including the potential for a new generation of lightweight bearings.
Cartilage a soft fibrous tissue found around joints that provides protection from compressive loading generated by walking, running or lifting is a bi-phasic porous material that exists in solid and fluid phases. It switches to its fluid phase by absorbing synovial fluid, a viscous substance produced in the joints.
This fluid lubricates the joints and when held in the porous matrix of the cartilage also provides a hydroelastic cushion against compressive forces. Because cartilage is porous, the synovial fluid eventually drains away and helps dissipate the energy forces travelling through the body, which protect ....

Inspired by nature, the researchers developing a new load-bearing material
Engineers have developed a new material that mimics human cartilage - the body s shock absorbing and lubrication system, and it could herald the development of a new generation of lightweight bearings.
Cartilage is a soft fibrous tissue found around joints which provides protection from the compressive loading generated by walking, running or lifting. It also provides a protective, lubricating layer allowing bones to pass over one another in a frictionless way. For years, scientists have been trying to create a synthetic material with the properties of cartilage. ....

Organic hydrogels can be a promising candidate for building long-term functioning glucose biosensors

Organic hydrogels can be a promising candidate for building long-term functioning glucose biosensors
In a new study, published online in the journal American Chemical Society (ACS)
Applied Polymer Materials, scientists at Texas A&M University reported they have designed a hydrogel membrane that may be used to house optical glucose sensing materials, toward building a biosensor for monitoring sugar levels in diabetics.
By incorporating dangling, comb-type molecular chains within a type of hydrogel called poly(N-isopropylacrylamide) or poly NIPAAm for short, they showed that the membrane could prevent leakage of small-sized molecules, like the ones for glucose-sensing, while still allowing glucose to freely diffuse in and out. ....
