  • Comparison of in situ and ex situ methods for synthesis of two-photon polymerization polymer nanocomposites 
    Guo, Qingchuan; Ghadiri, Reza; Weigel, Thomas; Aumann, Andreas; Gurevich, Evgeny L.; Esen, Cemal; Medenbach, Olaf; Cheng, Wei; Chichkov, Boris; Ostendorf, Andreas (Basel : MDPI AG, 2014)
    This article reports about nanocomposites, which refractive index is tuned by adding TiO2 nanoparticles. We compare in situ/ex situ preparation of nanocomposites. Preparation procedure is described, properties of nanocomposites ...
  • Correction to Comparison of in Situ and ex Situ methods for synthesis of two-photon polymerization polymer nanocomposites [Polymers, 6, (2014) 2037-2050] 
    Guo, Qingchuan; Ghadiri, Reza; Weigel, Thomas; Aumann, Andreas; Gurevich, Evgeny L.; Esen, Cemal; Medenbach, Olaf; Cheng, Wei; Chichkov, Boris; Ostendorf, Andreas (Basel : MDPI AG, 2014)

  • High-aspect 3D two-photon polymerization structuring with widened objective working range (WOW-2PP) 
    Obata, Kotaro; El-Tamer, Ayman; Koch, Lothar; Hinze, Ulf; Chichkov, Boris (London : Springer Nature, 2013)
    We developed a novel two-photon polymerization (2PP) configuration for fabrication of high-aspect three-dimensional (3D) structures, with an overall height larger than working distance of the microscope objective used for ...
  • Laser fabrication of 3D gelatin scaffolds for the generation of bioartificial tissues 
    Ovsianikov, Aleksandr; Deiwick, Andrea; Van Vlierberghe, Sandra; Pflaum, Michael; Wilhelmi, Mathias; Dubruel, Peter; Chichkov, Boris (Basel : MDPI AG, 2010)
    In the present work, the two-photon polymerization (2PP) technique was applied to develop precisely defined biodegradable 3D tissue engineering scaffolds. The scaffolds were fabricated via photopolymerization of gelatin ...
  • Layer transfer from chemically etched 150 mm porous si substrates 
    Terheiden, Barbara; Hensen, Jan; Wolf, Andreas; Horbelt, Renate; Plagwitz, Heiko; Brendel, Rolf (Basel : MDPI AG, 2010)
    We demonstrate for the first time the successful layer transfer of an epitaxially grown monocrystalline Si film from a purely chemically etched porous Si substrate of 150 mm diameter to a glass carrier. The surface ...
  • Optical spectroscopy of single SI nanocylinders with magnetic and electric resonances 
    Evlyukhin, Andrey B.; Eriksen, René L.; Cheng, Wei; Beermann, Jonas; Reinhardt, Carsten; Petrov, Alexander; Prorok, Stefan; Eich, Manfred; Chichkov, Boris; Bozhevolnyi, Sergey I. (London : Nature Publishing Group, 2014)
    Resonant electromagnetic properties of nanoparticles fabricated from high-index semiconductor or dielectric materials are very promising for the realization of novel nanoantennas and metamaterials. In this paper we study ...
  • Optical transparency by detuned electrical dipoles 
    Bozhevolnyi, Sergey I.; Evlyukhin, Andrey B.; Pors, Anders; Nielsen, Michael G.; Willatzen, Morten; Albrektsen, Ole (Bristol : IOP Publishing Ltd., 2011)
    We demonstrate that optical transparency can be realized with plasmonic metamaterials using unit cells consisting of detuned electrical dipoles (DED), thereby mimicking the dressed-state picture of the electromagnetically ...
  • Optically trapped probes with nanometer-scale tips for femto-Newton force measurement 
    Pollard, M.R.; Botchway, S.W.; Chichkov, Boris; Freeman, E.; Halsall, R.N.J.; Jenkins, D.W.K.; Loader, I.; Ovsianikov, A.; Parker, A.W.; Stevens, R.; Turchetta, R.; Ward, A.D.; Towrie, M. (Bristol : IOP Publishing Ltd., 2010)
    We describe the development of a novel force probe, controlled by multiple optical traps, with a nanometer-scale tip that protrudes outside the direct laser radiation field. We have measured forces to an accuracy of 240 ...
