Scientists have been exploring the use of tiny magnetic particles mixed with blood to improve heat transfer and potentially revolutionize medical treatments. These nanofluids, specifically Fe3O4/blood and CoFe2O4/blood, are being studied for their ability to enhance thermal conductivity and efficiency. The research focuses on how these nanofluids behave on an expone...
Tiny robots are making big waves in medicine. These little helpers, called microrobots, can move around without wires. They could one day help doctors treat patients without surgery. But there's a problem. Most microrobots are made from soft materials. They can't move well in fast-flowing blood. They also don't respond well to magnetic fields. This makes them hard to...
Cerium oxide nanoparticles are making waves in the world of medicine. These tiny particles are special because they can switch between different states. This makes them super stable and easy to produce in large quantities. Making these nanoparticles is like a science experiment. Scientists use different methods to create them. Some use heat, while others use special...
Tiny robots, smaller than the width of a human hair, are no longer just a dream. They are real and have the power to change the world. But why aren't we seeing them everywhere yet? The journey of these micro and nanorobots started with a famous lecture and a sci-fi movie. Now, they are used in medicine and cleaning up the environment. But there are big hurdles to ove...
Nanotechnology has been making waves in the medical field. It's all about tiny particles that can do big things. One of the most exciting areas is nanobiocatalysts. These are enzymes that have been attached to even smaller structures. This process is called immobilization. It helps enzymes work better and last longer. The idea is to use these tiny helpers in various...
Magnesium and its alloys are not just for bones. They are also being studied for their potential to fight liver cancer and viruses. This is big news because magnesium alloys are already used in bone repair and tissue engineering. But their effects on cancer cells? That's a different story. So, researchers decided to dive in and see what happens when magnesium an...
The ocean is a treasure trove of tiny, powerful helpers. These helpers are not your typical superheroes, but rather enzymes from marine microbes. These enzymes have a special ability to tackle biofilms, which are groups of bacteria that stick together and can cause big problems in places like hospitals. Biofilms are everywhere in nature and are incredibly tough to r...
The world of medicine has seen some amazing changes thanks to tiny particles called nanoparticles. These super-small bits can be used to deliver drugs right where they are needed in the body. Among these, polymeric nanoparticles stand out because they can be adjusted to fit different needs. Their surfaces can be changed to attach various molecules, making them useful...
Nanozymes are tiny machines that copy the work of natural enzymes. They are used in medicine and other fields. Some of these nanozymes have two metal atoms working together. These are called dual-atom nanozymes. They are better than the old single-atom ones. They do not clump together and they work faster. This is because the two atoms help each other out. The...
Bone repair is a big deal in medicine. Strong, effective implants are key to fixing bones. Recently, zinc (Zn) has shown promise as a material for these implants. Zinc is great because it breaks down naturally in the body, but it has some issues. Pure zinc can corrode quickly and doesn't always help bones grow as much as needed. Researchers have found a way to impro...
