Das Institut für Halbleitertechnik (AG Prof. Waag) und das Institut für Physikalische und Theoretische Chemie (AG Prof. Tinnefeld) beide Mitglieder des Laboratory for Emerging Nanometrology (LENA) der TU Braunschweig sind Partner des kürzlich gestarteten EU-Forschungsprojektes ChipScope, in dem  ein  neues, extrem kleines Lichtmikroskop entwickelt wird. Damit soll das Innere lebender Zellen in Echtzeit beobachtet werden können. Sieben Institute in fünf europäischen Ländern beteiligen sich über die nächsten vier Jahre an diesem technologisch äußerst anspruchsvollen Projekt.

Seit einigen Jahren beschäftigt sich die Forschung mit Antennen, welche knapp eine Milliarde Mal kleiner sind als unsere wohlbekannten Antennen am Badezimmerradio. Dabei handelt es sich im einfachsten Fall um kugelförmige Nanopartikel aus Metallen wie Gold. Sie können elektromagnetische Strahlung empfangen und aussenden, deren Wellenlänge im Nanometerbereich des sichtbaren Lichtes liegt. Nanoantennen gelten derzeit als vielversprechend um Licht auf kleinsten Skalen jenseits der optischen Auflösung kontrollieren zu können.

Forscher der TU-Braunschweig um Prof. Philip Tinnefeld und Dr. Guillermo Acuna (Institut für Physikalische Chemie, Forschungsbau LENA) haben einen entscheidenden Beitrag geleistet, um Eigenschaften dieser Antennen zu beschreiben. Dazu nutzen sie die sogenannte DNA Origami-Technik um Nanopartikel aus Gold gezielt neben Farbstoffmolekülen zu platzieren.
