Synopsis Optically Induced Nanostructures by : Karsten König
Nanostructuring of materials is a task at the heart of many modern disciplines in mechanical engineering, as well as optics, electronics, and the life sciences. This book includes an introduction to the relevant nonlinear optical processes associated with very short laser pulses for the generation of structures far below the classical optical diffraction limit of about 200 nanometers as well as coverage of state-of-the-art technical and biomedical applications. These applications include silicon and glass wafer processing, production of nanowires, laser transfection and cell reprogramming, optical cleaning, surface treatments of implants, nanowires, 3D nanoprinting, STED lithography, friction modification, and integrated optics. The book highlights also the use of modern femtosecond laser microscopes and nanoscopes as novel nanoprocessing tools.

Synopsis Fabrication of Photonic Structures by Two-Photon Polymerization by :
Since the publications of E. Yablonovitch and S. John in 1987 on the optical properties of three-dimensional periodic structures the interest on photonic crystals has increased rapidly mainly driven by progress in their theoretical description. On the experimental side, the fabrication of photonic crystals still remains a major challenge since the fabrication methods either lack quality, flexibility or resolution. Subject of this thesis is the development of a new technique for the generation of threedimensional structures on the sub-micrometer scale that is suitable for the fabrication of photonic crystals. The crystals fabricated using this technique are characterized and their optical properties are discussed. If near-infrared femtosecond laser pulses are tightly focused into the volume of a transparent, photosensitive resin, two-photon absorption within the focal volume leads to photopolymerization. By moving the laser focus three-dimensionally through the volume of the resin, any 3D structure can be fabricated by means of two-photon polymerization. After the polymerization process the non irradiated polymer can be etched away with special solvents leaving the solid 3D structure that was exposed by the focused femtosecond pulses. Due to the threshold behavior of the two-photon polymerization process, one can overcome the diffraction limit by choosing the applied peak laser fluence just slightly above the threshold for polymerization. In this case only the central part of the laser focus contributes to the polymerization process. It is shown that complicated 3D structures with a resolution as small as 100 nm can be fabricated by means of two-photon polymerization using a laser wavelength of l=780 nm. Woodpile structures having a face-centered-cubic symmetry and a photonic bandgap in the near infrared were fabricated with two-photon polymerization and were optically characterized by means of Fourier-transform infrared spectroscopy. Since the refractive index contrast in polymeric crystals is not high enough to provide a complete photonic bandgap, the fabricated woodpile structures were used as templates for the infiltration with highly refractive TiO2 and subsequent calcination of the polymer. For the first time, TiO2 replica of near infrared woodpile structures are shown. By adapting available algorithms developed for rapid prototyping techniques to the needs of two-photon polymerization, arbitrary 3D structures could be transferred from a computer generated model to the real world with feature sizes far below the used laser wavelength. For the first time, optically high-quality organic-inorganic hybrid polymers (Ormocer's) have been used for the fabrication of 3D microstructures by means of two-photon polymerization.

Synopsis Polymers for Photonics Applications II by : Kwang-Sup Lee
The future of information technology requires ultra high speed processing and large data storage capacity. Since the electronics technology using semi conduc tors and inorganic materials is about to reach its limits, much current research is focused on utilizing much faster photons than electrons, namely photonics. To achieve any significant effect on the actual use of the science of photonics, devel opments of more efficient photonics materials, better optical property evaluations, manufacture of devices for system applications, etc. are the subjects which need to be explored. In particular, the development of photonics materials stands in the forefront of research as this constitutes the most pertinent factor with regard to the development of ultra high speed and large capacity information processing. In this respect, there has been continuous research on photo responsive materials through molecular structure design and architecture and the results so far are very promising as functions and performances are beginning to realize their high expectations. The two special volumes "Polymers for Photonics Applications" give authorita tive and critical reviews on up to date activities in various fields of photonic poly mers including their promising applications. Seven articles have been contributed by internationally recognized and they deal with, polymers for second and third order nonlinear optics, quadratic parametric interactions in polymer waveguides, electroluminescent polymers as light sources, photoreflective polymers for holo graphic information storage, and highly efficient two photon absorbing organics and polymers.

Synopsis Light Robotics - Structure-mediated Nanobiophotonics by : Jesper Glückstad
Light Robotics – Structure-Mediated Nanobiophotonics covers the latest means of sculpting of both light and matter for achieving bioprobing and manipulation at the smallest scales. The synergy between photonics, nanotechnology and biotechnology spans the rapidly growing field of nanobiophotonics. Nanoscale resolutions enable optical scientists to assess ever more accurate information. However, scientific hypothesis testing demands tools, not only for observing nanoscopic phenomena, but also for reaching into and manipulating nanoscale constituents. Taking an application based focus, this book explores how nanophotonics can productively be used in both the biomedical and life sciences, allowing readers to clearly see how structure-mediated nanobiophotonics can be used to increase our engineering toolbox for biology at the smallest scales. This book will be of great use to researchers and scientists working in the fields of optics and photonics. It will also be of great value to those working in the field of biotechnology, showcasing how nanotechnology can help provide new, effective ways to solve biomedical problems. - Presents cutting-edge research on the principles, mechanisms, optical techniques, fabrication, modeling, devices and applications of nanobiophotonics - Brings together the diverse field of structure-mediated nanobiophotonics into one coherent volume - Showcases how nanophotonics can be used to create new, more effective micro- and nano-biodevices

Synopsis Bioprinting: Principles And Applications by : Wai Yee Yeong
At labs around the world, researchers have been experimenting with bioprinting, first just to see whether it was possible to push cells through a printhead without killing them (in most cases it is), and then trying to make cartilage, bone, skin, blood vessels, small bits of liver and other tissues. There are other ways to try to “engineer” tissue — one involves creating a scaffold out of plastics or other materials and adding cells to it. In theory, at least, a bioprinter has advantages in manipulating control of the placement of cells and other components to mimic natural structures.But just as the claims made for 3-D printing technology sometimes exceed the reality, the field of bioprinting has seen its share of hype. The reality is that, although bioprinting researchers have made great strides, there are many formidable obstacles to overcome. Nobody who has any credibility claims they can print organs, or believes in their heart of hearts that that will happen in the next 20 years, but for operations like hip replacement, advance in Bio-printing has made customization of certain body parts possible.This book will start from the concept of Tissue Engineering, covering various approaches in Scaffolds for tissue engineering, Bioprinting techniques and Materials for bioprinting, Cell processing, 3D cell culture techniques, Computational design and simulation, multi-disciplinary approaches in bioprinting and finally cover the applications of bioprinting.
