Scientists have cooked up a clever way to tackle a nasty pollutant called formaldehyde. This stuff is everywhere, from factories to dirty water, and it's not great for our health. The trick? They've given yeast cells a superpower boost. First, they tweaked the yeast to produce more of an enzyme that breaks down formaldehyde. Then, they added tiny nano-particles that...
Citrus fruits pack a punch with vitamins and plant-based goodies. These include things like flavonoids and vitamin C. They can fight off harmful stuff in our bodies. But there's a catch. These goodies often break down before we can enjoy their benefits. So, what's the solution? Tiny tech, or nanotechnology, is stepping in to help. It uses super small carriers, like ...
In the world of medicine, tiny tools are making a huge difference. Scientists are using super-small technologies to fight diseases and deliver medicines in smarter ways. These tiny tools, called nanotechnology, are like tiny robots that can target specific parts of the body. This means medicines can work better and cause fewer side effects. But that's not all. Scien...
Scientists have created a new way to fight cancer using tiny particles that glow and make cancer cells self-destruct. This method uses light to kill cancer cells, but unlike other treatments, it uses a special kind of light that can go deep into the body. The key to this treatment is special glowing particles called UCNPs. These particles work with other tiny molecul...
China is now a top player in global science, ranking fifth in scientific publications. The number of times Chinese research is cited has been growing fast. This growth is especially noticeable in areas like nanotechnology, where China is now second only to the USA. Money for research and development (R&D) has been increasing quickly since 1997. Interestingly, more o...
Cancer cells are sneaky. They have a way of protecting themselves, making it hard for treatments to work. One of their tricks is having high levels of a substance called glutathione. This helps them grow and resist treatments. Scientists have been looking for ways to lower glutathione levels in tumors, but existing methods have problems. They either don't work well o...
Dr. Katsuhiko Ariga is a big name in the world of tiny things. He's turned 60, and his work has changed how we see and use nanotechnology. This is not just about making things small. It's about building them smartly. Ariga's work is like playing with building blocks. But these blocks are super tiny. He uses them to create new materials. These materials can do amazin...
Scientists have created a new tool to help clean up dirty water. They made special foam with tiny bits of graphene and a mix of nickel and cobalt. This foam can help break down a harmful chemical called 2, 3-dichlorophenol. The foam is put into a tube, and water flows through it. The foam uses light to help clean the water. The foam is made by mixing graphene with a...
Fruits and vegetables often go bad after harvest. This is a big problem. It affects food safety and quality. To tackle this, scientists are looking at new ways to use natural helpers, like bacteria and fungi, to keep produce fresh. These helpers, called biocontrol agents (BCAs), can fight off diseases that spoil food. But using them alone might not be enough. So, re...
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...
