A team of researchers from the Optics Group at the Universitat Jaume I in Castelló has developed a system for producing nanoparticles using lasers. The invention has potential applications in various business sectors, such as the biomedical industry (in the form of contrast agents in imaging or drug carriers), the energy industry (for the manufacture of advanced thermal fluids), and materials engineering (to develop new materials or improve the performance of existing ones).

The manufacture of nanoparticles using lasers stands out for its ability to produce high-purity nanoparticles, free of chemical contaminants, from virtually any solid material in an environmentally friendly and highly versatile process. In general, the energy provided by high-power lasers exceeds the optimum required for the manufacture of nanoparticles in fluids.

The system developed by the UJI team uses an ablation chamber (a chamber in which the materials and the appropriate fluid are deposited) with two transparent windows, allowing irradiation on both sides of the same material or different materials. In addition, to make better use of this energy, advanced focusing systems are used to change the way the energy is deposited on the sample.

This allows for increased productivity and the simultaneous manufacture of nanoparticles from different materials, and also makes it possible to reduce the extreme conditions of the halo that can damage the system components. In addition, the shaping unit allows one or multiple foci to be generated, as well as modifying their profiles or correcting aberrations. The incorporation of nanomaterials into other materials can improve their performance, uses, functions, or even their durability.

The procedure, validated on an experimental scale in the laboratory environment and protected by a Spanish patent application, seeks collaboration with companies for the development and adaptation of the technology to specific applications through specific agreements and subsequent licensing agreements.

The Universitat Jaume I, through the Cooperation and Technological Development Office and the Vice-Rector's Office for Transfer, Innovation and Scientific Dissemination, promotes the scientific and technological transfer of its research staff, in line with its commitment to sharing and disseminating scientific, technical, social and humanistic knowledge.

The research carried out to achieve this new system has been funded by the State Research Agency (Knowledge Generation Projects 2022 and Research Challenge Projects 2019) and the Regional Ministry of Innovation, Universities, Science and Digital Society (GVA), through the Programme for the Promotion of Scientific Research, Technological Development and Innovation in the Valencian Community /2020/029 and CIPROM/2023/44.
