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: ....
