Why do you think your paper is highly cited?

The paper shed light on a new property of nanoparticles, which was not previously known: the ability to self-organize under the influence of local interactions between the particles. As it turned out, this property determines the behavior of particles in many solutions.

Does it describe a new discovery, methodology, or synthesis of knowledge?

"The process described in the paper can significantly simplify the manufacturing of nanowires..."

The paper describes the process of self-organization of particles in the chain under the influence of dipole-dipole interactions between them and the subsequent recrystallization of the chain in nanowires. This is a unique process that opens up a new methodology for building up nanoscale systems.

Would you summarize the significance of your paper in layman’s terms?

The process described in the paper can significantly simplify the manufacturing of nanowires. It also highlights the similarity between the behavior of inorganic particles and proteins, the building blocks of live matter.

How did you become involved in this research and were any particular problems encountered along the way?

We were looking for new methods to make highly luminescent nanoparticles.

Where do you see your research leading in the future?

Establishing the general analogy in the behavior of proteins and nanoparticles can lead to multiple new directions in both science and biomedicine. As such, one can anticipate new drugs based on the existence of biocompatible nanoparticles.

Do you foresee any social or political implications for your research?

Not immediately, which is probably a good thing for the further development of this work.
