Kann Aloe Vera bei der Züchtung von Knochenzellen helfen, Frau Goonoo?
In Siegen holt sich Nowsheen Goonoo jeden Tag ein Stück Heimat ins Labor. Die aus Mauritius stammende Wissenschaftlerin experimentiert mit Inhaltsstoffen aus Pflanzen, die dort heimisch sind.
"Schon mein Großvater kannte die Wirkung der Aloe vera und hat damit meine kleinen Wunden geheilt“, erinnert sie sich. Was die Chemikerin aus der Pflanze nutzen möchte, sieht aus wie ein aufgequollenes Gummibärchen: das Gel aus dem Wasserspeichergewebe der Blätter. In Kosmetika ist es schon lange ein wichtiger Inhaltsstoff. Goonoo will aus Bestandteilen des Gels und weiteren synthetischen Polymeren Fasern für ein Trägermaterial herstellen, das Zellwachstum unterstützen kann.
