The German Research Foundation (DFG) will promote "Collaborative Research Center 1227 – Designed Quantum Material States" (DQ-mat) for four more years and provide roughly 9.2 million euros in funding. The DFG's senate announced this decision after its session on 28 May 2020. "The scientists working in the DQ-mat Collaborative Research Center have demonstrated their outstanding performance during the last four years. I am very pleased with this decision and would like to thank them for their great dedication. Once again, the DFG's vote shows that Leibniz University is also among the leading universities in Germany and beyond in the field of quantum optics," explains Prof. Volker Epping, the President of Leibniz University. In addition to Leibnitz University, the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig is involved in the Collaborative Research Center.

Wissenschaftler der Physikalisch-Technischen Bundesanstalt (PTB), Institut Berlin, haben die innovative Methode der digitalen Tröpfchen-PCR für den Nachweis von SARS-CoV-2 angepasst und nun in einer internationalen Vergleichsmessung (einem Ringvergleich) zur Qualitätssicherung erfolgreich eingesetzt. An dem Vergleich, der von der Gesellschaft zur Förderung der Qualitätssicherung medizinischer Laboratorien e. V. (INSTAND e. V.) in Zusammenarbeit mit dem Nationalen Konsiliarlaboratorium für Coronaviren des Instituts für Virologie der Charité (Prof. Dr. Christian Drosten) durchgeführt wurde, waren 470 medizinische Laboratorien aus 36 Ländern beteiligt. In Zukunft könnte die Methode aus der PTB als Referenzmessverfahren für den Virus-Genomnachweis zur Qualitätssicherung von PCR-Analysemethoden in medizinischen Laboratorien eingesetzt werden. Bei der Methode werden die Tröpfchen, die die typische RNA-Sequenz des Virus enthalten, direkt...
