TY - GEN A1 - Schäferling, Michael T1 - Luminescent Imaging with Optical Chemical Sensors N2 - The intention of this compilation of articles was to introduce brand-new developments in the field of chemical imaging which have not been discussed in previous review articles. These include the design of new sensor nanomaterials based on photon uponversion crystals which convert near-infrared excitation light into sensor signals in the visible wavelength range highlighted by Christ and Schäferling. Sun, Ungerböck and Mayr describe the state of the art in oxygen imaging in microreactors and microfluidic devices. Miniaturized sensors for the imaging of oxygen, pH and temperature in microchips, microfluidic platforms and microbioreactors are reviewed by Pfeiffer and Nagl. Furthermore, Dmitriev and Papkovsky present a critical assessment of the applicability of probes for intracellular oxygen sensing. I hope these articles provide an interesting insight into advanced luminescent sensor materials and the applications of optical micro- and nanosensors in fluorescence imaging today and will be inspiring for the reader. Finally, I would like to thank all authors and referees for spending their time to enable this collection of articles.
