By covalent incorporation of diethynyl pyrrolo-pyrrole or diethynyl fluorenone in the miniemulsion polymerization the emission color of these photostable nanoparticles can be tuned from blue ( Éem max 470) to orange at a given excitation wavelength due to an efficient energy transfer to these acceptors. Two-photon action cross sections of the particles amount to 106 to 107 GM. The particles from emulsion polymerization are taken up by HeLa cells without an adverse effect on the cells. Differentiation of the location in cells of particle species varying in emission color was demonstrated for both linear and two-photon excitation microscopy in the NIR regime.</dcterms:abstract> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9929"/> <dc:creator>Pecher, Johannes</dc:creator> <dc:creator>Mecking, Stefan</dc:creator> <dcterms:issued>2010</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:23Z</dc:date> <dc:creator>Huber, Johannes</dc:creator> <dc:format>application/pdf</dc:format> <dc:rights>deposit-license</dc:rights> <dc:creator>Winterhalder, Martin</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:language>deu</dc:language> <dc:creator>Zumbusch, Andreas</dc:creator> <dc:contributor>Pecher, Johannes</dc:contributor> <dc:contributor>Mecking, Stefan</dc:contributor> </rdf:Description> </rdf:RDF>
