Silk

Microplastics are a major environmental problem, but a new study could help cut out a decent chunk of them. Silk could be a biodegradable replacement for microbeads and particles that are often added to cosmetics, paints and other products.

When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.

An experimental new material could help rehabilitate the injured and allow the nonspeaking to "speak," among other potential uses. It's also highly elastic, electrically conductive and self-healing – and it's known as CareGum.

Adhesives that hold underwater are elusive, but could be useful for marine repairs or tissue healing. Researchers have now developed a new type of adhesive hydrogel that combines the underwater stickiness of mussels with the strength of spider silk.

Spider silk is one of nature’s most impressive materials, exhibiting impressive strength and toughness. Now, researchers at Washington University in St. Louis claim to have created an artificial version that can outperform some natural spider silks.

By mimicking the self-assembling microstructures that give spider silk its incredible strength, scientists have produced a plant-based film with the strength of common single-use plastics, offering a "vegan" eco-friendly alternative.

As useful a material as leather is, it isn’t too environmentally friendly. Now, engineers at Tufts University have created a new leather-like material out of silk, which can be 3D printed into shape and easily recycled into new products as needed.

Along with its use in clothing, silk also shows promise for use in products ranging from surgical sutures to seed coverings. Scientists have recently devised a method of making the material stronger, by altering the diet of silkworms.

Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.

A new substance is claimed to combine strength and toughness, by mixing wood fibers with spider silk.

It’s no secret that spider silk is one of nature’s most incredible materials. Now scientists have discovered a weird new ability. A team led by MIT has found that when exposed to a certain level of humidity, spider silk suddenly shrinks and twists, which could make it useful in artificial muscles.

​If you need to close up an injury or incision in human body tissue, you use sutures, staples or a surgical adhesive … right? Well, if technology that's currently being developed at Arizona State University gets commercialized, liquid silk combined with gold may eventually be a better way to go.
