I became very attracted to utilise my knowledge in the field of medical and biochemical applications. Financially supported by a VENI-grant via STW, I am currently investigating nanostructured surfaces, which are made by various techniques (see Figure 1). I think that these structures three-dimensionally confine (bio)chemical reactions yielding higher or at least more accurate conversion and selectivity. At the length scale of individual molecules relevant physico-chemical effects can be studied, for example, by Inelastic Electron Tunneling Spectroscopy (IETS), a technique being used a lot in nanoelectronics.

Combining large-area nanostructuring with IETS may lead to a statistically relevant interpretation of the properties of molecular assemblies at such nanoconfined surfaces. The results may present us with a fingerprint of the individual molecules in the nanoassemblies. These findings will also contribute to the better understanding of shape-selective processes.

In my vision, many diseases may be treated by locally defined stimulation of brain tissue controlling the biosignalling cascade of cells in-vivo. My interest is focused on the design and fabrication of a nanosystem, which electrically controls the molecular conformation at the interface between a man-made device and biological material. Figure 2A-F envisions such triggered interaction cascade by definition and transduction of the proper biochemistry at the device surface.

I am engaged in a number of projects linked to the field of Lab-on-a-Chip as a platform technology. In this area of work, carried out at MESA+ Institute for Nanotechnology, I aim for the integration of components manufactured at the micro-and nanoscale to higher functional devices following the approaches of formal design. The success of higher architecture systems goes hand in hand with the fundamental understanding of the phenomena occurring at the small scale. My expertise extends from the definition of fabrication techniques in glass, silicon and plastics to the investigation of chip-based microfluidics for applications at the Point-of-Care, including microneedle arrays for novel skin patches. The utilisation of these research results towards product development was awarded by STW with valorisation grant phase 1 and 2 helping to initiate two new start-up companies (Medimate and MyLife Technologies) aiming for medical devices based on Lab-on-a-Chip platform technolgy.

I finalized my PhD-project in 2003 at the University of Londen (Imperial College), UK in the Optical and Semiconductor Devices Group. My thesis was dedicated to the investigation of fabrication technologies for optical scanners based on micromachined cantilevers in the research area of microopto-electromechanical systems (MOEMS).
