Researchers at the National Laboratory of Condensed Matter Physics at the Institute for Research in Fundamental Sciences have unveiled a one-step method for producing protonic nanosensors designed for respiratory monitoring. The approach uses a low-energy laser to form micro-patterns and functional nanostructures simultaneously, eliminating the multi-stage procedures that traditionally complicate nanoscale device manufacturing.

According to the research team, the method reduces production time, lowers costs and minimises structural inconsistencies that often arise during multi-phase fabrication. To demonstrate the capability of the technology, the scientists developed a proof-of-concept protonic sensor intended for real-time breath analysis. The device showed fast and stable performance at relative humidity above 55 per cent – the typical range found in human exhalation – and was able to track rapid changes in breath moisture with high accuracy.
Advances in respiratory monitoring have become increasingly important for early detection of acute and chronic respiratory irregularities. Wearable or portable systems require sensors that are compact, responsive and affordable, making simplified fabrication methods essential for wider adoption in both personal and clinical settings.
The one-step laser technique is compatible with a broad range of materials, meaning its potential applications extend beyond protonic sensors. It may be used in the development of catalysts, photonic components, energy-storage elements and other medical monitoring devices. Researchers highlight that the reduced equipment requirements and low energy consumption also support more sustainable manufacturing practices.
The team anticipates that the single-stage approach could serve as a base method for large-scale production of functional materials, opening the way for the commercialisation of next-generation sensing systems.
