Force Probe Microscopy and Surface Nanoengineering Group

Group Leader: Jordi Fraxedas

Main Research Lines

  • Force probe spectroscopy and metrology
  • Self-sustained motion and catalytic micropumps
  • Interfacial water
  • Polymer-based interfaces
  • Nanoparticles of organic superconductors

The group has participated in several projects at the European and Spanish level. Within the European FP7 and H2020 funding programmes, the group has been involved in the development of advanced atomic-force microscopy (AFM) instrumentation and the directed self-assembly of block co-polymers in collaboration with leading European universities and companies. A prototype of an AFM head has been successfully tested in an industrial environment, with a robot arm providing real-time information on the mechanical properties of surfaces of industrial interest (plastic injection moulds, solar cells, etc.). A fast-scan ARM module is also under design.

At the Spanish level, the group has participated in two projects focused on tailoring the affinity of water to surfaces and to micro/nanofluidics using carbon-based materials (nanotubes and graphene). The main objective is to be able to control the dynamics of water at different interfaces, for instance, structuring water as ice at temperatures above 0°C  or inducing mass transport via electrokinetic processes.

In terms of technology transfer, the group has secured a European patent (PCT/EP2016/057782) and a Spanish trade secret.
