Current Research

We explore on curious nanoscale phenomena at the interfaces between soft and hard matter, with particular interest in nanopore sensors, nanofluidics and nanoelectronics.

While pursuing in-depth scientific understanding, our research group drives the development of technologies in the fields of medical diagnostics, water filtration and energy harvesting. Those include:

  • Single-molecule DNA sequencing using nanopores
  • DNA data storage
  • Rapid detection of contaminants in cell therapy manufacturing
  • Nanofluidics and programmable materials
  • Novel membranes for filtration and blue energy harvesting
  • Advanced method for water purification

Our translational research resulted in 10 patents (granted or pending), out of which 5 patents are licensed by a major biotech company. Upon extensive research in electrochemical water treatment, our laboratory spun-off a cleantech company ReActo, focused on removing persistent contaminants from water.
