Biomolecules and nanostructuresThe Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
Active ControlActive control of the amplitude and phase of femtosecond light pulses allows us to create optical melodies. Such tailored pulse shapes can be fine tuned to specific electronic and vibrational response of a molecule to control its behavior in real time. We are pursuing applications in spectroscopy, medical diagnostics or treatment and the optimization of solar cell materials. |
Passive ControlThe direct (nano-)environment of a molecule influences its interaction with light. Collective (plasmon) oscillations can be excited on structured surfaces, decay can be enhanced or delayed and light can be made to refract in extraordinary ways in the right combination of materials. We design and create these environments, and then study the light and molecules within them. |
Technology DevelopmentThe creation of nanostructures, the control of fields with interferometric precision and the detection of the emission of single molecules requires state of the art technology. We develop this technology to create the smallest structures and most sensitive detection, for the benefit of our own research and others in the MESA+ institute. |

1st prize (F.B. Segerink): "An image of a nanostructure that unfortunately did not make it. The electron microscope image shows a piece of glasfiber which was pulled into a very sharp end (diameter < 100 nm), subsequently coated with aluminium. With a focused ion beam machine, you can remove the coating at the very end of the fiber, so that it can be used as a nano-lightsource in a near field optical microscope. In this case however, the producer (yours truly) obstructed this fine destination by mounting the fiber not too gentle in the dual beam machine (a combined focused ion- and electron beam). The image shows signs of charging by the electronbeam of uncoated areas." |

| Martin Jurna appeared in the dutch national tv show "de Wereld draait door" on april 13, 2009. Robbert Dijkgraaf, the head of the dutch science research institute Koninklijke Academie van Nederlandse Wetenschappen (KNAW) invited Martin along with 2 other young scientific researchers in this show. |

The so called 'Optical Techniques (OT) projects' are research projects that were inherited from the period that Niek van Hulst was still the
chair of the group. At that time, Optical Sciences group was called the Optical Techniques group.
The research focus was more on near field optics and single molecule detection by means of confocal microscopes and Near Field Scanning Microscopes (NSOM) utilizing fluorescence detection.
Our research is being supported in part by the following organizations, to whom we are grateful:
Optical Sciences group - Department of Science & Technology University of Twente
