European grant to Prof. Amit Meler from the Technion in the field of nanotechnology

  • No comments
The research group of Amit Meller from the Technion won a special grant from the European Union designed to accelerate an innovative technology for drilling nanometer nozzles in a material using a laser beam. The final device will be used for the analysis of a single molecule for the rapid diagnosis of diseases, including COVID-19

Applying a magnetic field to a non-uniform nanostructure. The measurement of the non-uniformity in the structure on the nanometer scale is performed by the optical spin Hall effect - measuring the spin splitting of the photons scattered from the structure using a "weak measurement". The spinners (blue and red) represent the two spin directions - the degree of spin of the scattered photons. (Image credit: Ella Maru Studio)

Researchers at the Technion have developed a technology that combines nano-optics and magnetism to diagnose nanometric non-uniformities in electronic chips and photons

Differences in the cellular environment (acidity and metabolism) affect the solubility of metal oxides, in the present example copper oxide (CuO). The researchers hypothesized that plating the oxide with iron atoms could provide a therapeutic window to fight cancer. This means a release rate that is fast enough to target the cancer cells, but one that slows down significantly in healthy cells.

Copper-based nanomaterials can destroy cancer cells
