Scientists Develop ‘Atomic Stencilling’ to Paint Nanoparticles

On 22nd October 2025, researchers from the US and South Korea unveiled a novel “atomic stencilling” technique that allows microscopic gold nanoparticles to be ‘painted’ with polymer patches — a breakthrough that could revolutionize nanotechnology, materials science and medicine.

Why It’s Important

Atomic stencilling helps overcome a major challenge in nanotechnology — making nanoparticles that can self-assemble into complex 3D structures and perform specific functions. It opens up new possibilities for:

• Designing metamaterials that manipulate light and sound.
• Creating targeted drug delivery systems.
• Developing next-generation catalysts and smart materials.

Advantages and Applications

• Customizable Design: Enables fine-tuning of nanoparticle properties for diverse applications.
• Next-Generation Materials: ....
