Nano-plasmonic sensors

In the past, we have developed nanoplasmonic sensing systems (nPLEX/NPS) for exosome analysis in cancer. Ongoing projects are in the fields of highly multiplexed exosome analysis as well as for single molecule analysis.

- The nPLEX sensor was highlighted as one of the greatest hits among 20 years of Nature Biotechnology biomedical research.

Digital diffraction diagnostics (D3)

Exploiting digital diffraction principles we have developed advanced photonics diagnostics implemented on smartphones or free standing optical systems. Inexpensive miniaturized systems incorporating cloud computing have been developed for global health applications.

Artificial intelligence

We are looking for a new opportunity to obtain diagnostic information accurately and effectively from acquired data. Using machine learning-based data analysis, we aim to interpret multiplexed data for spectroscopy, digital diffraction and imaging analysis. Combined with cloud computing, deep learning approaches could be the next revolutionary changes in analytical science and medicine.
