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...
Copper is everywhere. It is in the water we drink and the soil we walk on. But too much of it can be harmful. This is why finding ways to measure copper levels accurately is so important. A new method has been created to do just that. It uses a clever trick of light and chemistry to spot copper in our environment. The method uses tiny particles called carbon quantum...
The world of medicine is always looking for better ways to treat diseases. One exciting area is smart drug delivery. This is where drugs are released only when certain conditions are met in the body. This approach is especially useful for blood-related diseases. These smart systems work by reacting to specific signals or environments in the body. They combine the dru...
In the world of medicine, early detection is key. This is especially true for bladder cancer. A recent study has shown that a new method can spot signs of bladder cancer in urine. The method is a big step forward in how doctors can catch this disease early. The process uses tiny, specially designed gold and silver particles. These particles are shaped like trian...
In the fight against breast cancer, a new approach is gaining attention. It involves tiny, smart particles that can target and attack tumors in multiple ways. These particles are designed to overcome two big challenges: low oxygen levels in tumors and high levels of a substance called glutathione. This substance protects cancer cells from damage. The new strategy use...
Bionanotechnology is a big word for a tiny but powerful idea. It is the mix of biology and nanotechnology. This mix is changing how we tackle environmental problems. It is not just about fixing issues but also about creating new, sustainable solutions. The tiny size of nanomaterials and the adaptability of biological systems make this possible. This combination opens...
