Applications
Technology Applications & Benefits
NO2 gas sensing
Our MoS₂-based material enables the development of advanced NO₂ chemo-resistive gas sensors characterized by high sensitivity (ppb), humidity resistance, and strong selectivity towards NO₂. It also detects CH₄, H₂, and NH₄ at ppm levels, making it suitable for environmental monitoring, industrial control, and safety systems.
Production of Ws2 nanopores
We engineer WS₂-based nanopores tailored for ionic current measurements and molecular analysis, leveraging the unique properties of 2D materials. Their exceptional structural stability and favorable electronic characteristics make them ideal for integration into biosensing platforms and advanced analytical tools designed for single-molecule detection.
Ultra-sharp materials for nano-photonics
Our ultra-sharp 2D materials are applicable in fields such as nanophotonics, extreme ultraviolet (EUV) lithography, and X-ray imaging. Their dimensional precision and optical characteristics support the development of components for high-resolution imaging and light manipulation at the nanoscale.
Production of EBL calibration marks
Our materials are used in the production of calibration marks for electron beam lithography (EBL), ensuring alignment precision and reproducibility in nanoscale fabrication processes. These marks are applicable in research and manufacturing environments where high patterning accuracy is required.

Research & Development
Our work is based on several scientific publications
Everything we do at Smena is solidly based in science. Our founder Timur Shegai is a world class physicist (having published as last author in Nature magazine on the topic of light-matter interaction) and is actively involved in everything we do. You can trust that the knowledge built in his research group at Chalmers University of Sweden is part of any delivery from Smena.
We at Smena strive for a green development
Sustainability, a big word. At Smena this means we think several hundred years ahead. Only then can human activity be truly sustainable. Honestly, almost nothing we humans do presently can be seen as truly sustainable. You can trust that Smena is doing our utmost to think really long term, and taking care of both ourselves and our planet.
We use a scalable resource
MoS2 can be found in nature as a relatively abundant mineral – molybdenite, which is an infinitely scalable resource. MoS2 is a semiconducting 2D analog of famous graphene.
It is believed that thanks to the remarkable physical, chemical, optical and mechanical properties, the material will find use in future industries.
