Edelgas in Molekülkäfig detektiert Immunprozesse

PTB-Forscher sind Gewinner des Innovationswettbewerbs Medizintechnik des BMBF

(PresseBox) (Braunschweig, )
Mit Magnetresonanztomographie (MRT) Funktionsstörungen von Herz und Hirn ohne Eingriff in den Körper aufzuspüren, ist bereits ein etabliertes Diagnoseverfahren. Nun wollen Wissenschaftler der Physikalisch-Technischen Bundesanstalt Berlin (PTB) gemeinsam mit Kollegen der Freien Universität Berlin (FUB) die MRT so „scharfsichtig“ machen, dass sogar das Bindungsverhalten einzelner immunologisch wichtiger Moleküle im Körper sichtbar gemacht werden kann. Dies soll durch einen Biosensor gelingen, der unter anderem das Edelgas Xenon enthält, dessen MRT-Signal um mehrere Größenordnungen erhöht werden kann. Da Edelgase für gewöhnlich keine Bindungen eingehen, greifen die Forscher zu einem Trick: Sie sperren das Xenonatom in einen Molekülkäfig und binden diesen an das Eqfdukicjbogjmgamd pibtr Lereiiegpm.
