23_19i/2013Sensors: Thin-Wall Assembled SnO2 Fibers Functionalized by Catalytic Pt Nanoparticles and their Superior Exhaled-Breath-Sensing Properties for the Diagnosis of Diabetes (Adv. Funct. Mater. 19/2013)

Thin-wall assembled SnO2 tubes with a number elongated pores are synthesized via electrospinning, controlled by the variation of flow rates. On page 2357, Il-Doo Kim and co-workers report that these highly porous SnO2 tubes show a five-fold higher acetone response compared with dense SnO2 fiber in a humid atmosphere that is similar to the oral cavity. The accurate detection of acetone gas in exhaled breath can provide useful information for real-time diagnosis of diabetes.
