Gateway for scientists


Here you will find current news from PTB's diverse research activities as well as a short guide to PTB.


Seit 1. Juni 2022 arbeiten das BRICS, ein Forschungszentrum der TU Braunschweig, und die Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig auf einem weiteren Gebiet offiziell zusammen. Bei der jetzt vertraglich vereinbarten Kooperation steht die Standardisierung im biomedizinischen Bereich im Mittelpunkt: Erforscht werden sollen weltweit geltende, objektive Maßstäbe für quantitative Messungen in der Biomedizin, also Einheiten, Grenzwerte und Messmethoden, die möglichst auf das internationale Einheitensystem SI rückgeführt werden können. Wichtig ist das zum Beispiel bei der Verabreichung von Medikamenten wie bei der Insulintherapie und bei der Cholesterin-Diagnose.
