Nanofibrous semiconductor metal oxides (SMOs) functionalized by Pt-based bimetallic catalysts are synthesized by bioinspired protein templates by Il-Doo Kim and co-workers in article number 1700737. Pt-based bimetallic catalysts such as PtPd, PtRh, and PtNi are uniformly functionalized on the surface of the SMO nanofibers. As a result, exceptionally high sensing performance is achieved by selective detection of the biomarker species, such as acetone and hydrogen sulfide, in exhaled breath with potential application in the diagnosis of diseases by analyzing exhaled human breath.
