摘要
(Figure Presented) Sensitive sponges: Nanosponge titania (NST), integrated into a prototype device, has been used for ultrasensitive detection of hydrogen. NST has potential applications in multiplex sensing systems such as electronic noses and tongues, and three-dimensionally interconnected nanostructured metal oxides hold great promise as platforms for ultrasensitive sensors. The picture shows an SEM image of NST formed from 500-nm-thick Ti film. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
