Cartilage repair is a tough job. Why? Because cartilage does not have blood vessels or cells. This makes it hard for the body to fix itself. But there is hope. Scientists are working on a solution using injectable hydrogels. These are like tiny, flexible sponges that can be injected into the body. They have shown great promise in helping cartilage grow back. Injecta...
The body's tissues are built tough, thanks to collagen. Collagen fibers run in specific directions, giving tissues their strength and stability. Scientists have been trying to copy this design. They have had a hard time making models that match the size and direction of natural tissues. Now, a breakthrough has been made. Scientists created new collagen tissues. ...
Imagine trying to build something with a material that keeps shrinking. That's a big problem in tissue engineering. Scientists have been using collagen-based hydrogels, which are great for growing cells, but they have a nasty habit of shrinking when cells interact with them. This makes it hard to create stable structures for things like drug testing or even growing n...
Building bones from scratch for medical needs is a hot topic in science. 3D printing is a big deal in this field. It's all about creating materials that match real bone tissue. This is tricky because bones have a complex structure. Scientists are exploring new ways to make this happen. Imagine printing bone structures that are as intricate as a spider web. T...
Burns can be a real challenge to treat. But scientists have come up with a clever solution inspired by nature. They've created a special gel that helps wounds heal faster. This gel is made from chitosan and silk fibroin, with a touch of tannic acid and riboflavin, which helps it stick well to the skin. It has two layers: the top one is filled with tiny holes to help ...
When it comes to growing new bones, scientists are exploring how to design the best scaffolds for the job. These scaffolds need to be good at helping new bone grow and strong enough to hold up. Researchers have looked at different types of materials, like metals, non-metals, and polymers, to make these scaffolds. They've also considered different ways to make these s...
Oral bone tissue loss is a big problem. It can happen due to conditions like osteoporosis, tooth removal, or even being overweight. Traditional fixes have issues like hurting the donor site or causing inflammation. Now, scientists are exploring new materials that mimic natural bone. One standout is insulin, a hormone known for controlling blood sugar. But it also hel...
Bone tissue engineering faces challenges that require advanced materials. One strategy is to create composite scaffolds. These scaffolds need to support bone repair and have enough strength. Researchers tried making a scaffold from bacteria, mineral, and graphene. Each part is sourced from waste, like food and farming leftovers. Bacterial cellulose is ideal due to it...
