Physicists were able to fully structure the substance on a nanoscale scale using laser beams.

Scientists have structured a thin film of gold with low-energy ring-shaped laser pulses.

With the help of tightly focused spatially-structured pulses in the film, holes are created with gold nanodiscs inside.

We have demonstrated a great opportunity.the use of a fully optical approach for structuring substances at the nanoscale and efficient plasmon nano probing. The result shows new opportunities that the amplifying effect of the interaction of structured light and structured matter opens up.

The results of this study can be used to create nanosensors that recognize various biological and chemical substances, including harmful and dangerous ones.
