Scientists have found a way to make a powerful microscope work better with tiny drug particles in water. This microscope, called a scanning electron microscope (SEM), usually needs a vacuum to work, but it can also be used to look at things in liquid. The problem is, small drug particles and other organic materials don't stick well to the microscope's viewing area. They also get damaged easily by the microscope's beam and don't show up clearly.

To fix these problems, researchers tried a few new things. First, they changed the surface of the viewing area to help the tiny particles stick better. This is something that has been done before with cells, but not with small organic materials. They also used spacers to make sure they could see a good mix of particle sizes. Another trick they used was adding a special chemical called gadolinium acetate. This made the particles show up more clearly and in better detail.

With these improvements, the microscope could now see details as small as 10 nanometers in tiny protein particles. This is a big deal because it helps scientists understand how these particles behave in water. This information is important for making better drugs and understanding how they work in the body.

The best part is that these improvements make the microscope useful for more than just cells and inorganic materials. Now, it can be used to study all kinds of organic and biological materials in water. This could lead to big advances in drug development and design.
