In Brandmeldern und Wasseraufbereitern verrichten sie ihren lebensrettenden Auftrag, und die Nachfrage nach ihnen steigt in vielen Bereichen wie Umwelt oder Industrie stetig an: UV-Licht-Sensoren. Wissenschaftlerinnen und Wissenschaftlern der Christian-Albrechts-Universität zu Kiel (CAU) ist es nun gelungen, innerhalb weniger Sekunden Nanostrukturen zu "backen", um damit ultraschnelle Sensoren herzustellen. Das neue Verfahren verzichtet völlig auf teure Geräte und giftige Chemikalien und ist insbesondere für Unternehmen hochinteressant. Die Forschenden veröffentlichten ihre Arbeit heute (19. November) online in der renommierten Fachzeitschrift "Advanced Materials".
