Sensors: 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)

Abstract

Thin‐wall assembled SnO2 tubes with a number elongated pores are synthesized via electrospinning, controlled by the variation of flow rates. , 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.

Nanofibers Comprising Yolk-Shell Sn@void@SnO/SnO2and Hollow SnO/SnO2and SnO2Nanospheres via the Kirkendall Diffusion Effect and Their Electrochemical Properties

“…Nanostructured tin dioxide (SnO 2 ) materials with a wide bandgap of 3.54 eV are widely used in various fields such as gas sensing, catalysts, and energy storage . In particular, SnO 2 materials with a specific nanostructure featuring both a short Li + ion diffusion length and sufficient void space to accommodate the volume change during cycling have been developed by liquid solution and gas phase reaction processes for applications in lithium ion batteries (LIBs).…”

Advances in triboelectric nanogenerators for self‐powered wearable respiratory monitoring

“…34,35 Furthermore, acetone concentration is higher in diabetic patients, making simple breath analyzers ideal for continuous acetone monitoring. [36][37][38] An abundant selection of wearable respiratory devices currently exists for measuring both mechanical and chemical respiratory information. [39][40][41][42] Wearable respiration devices show several advantages over their stationary counterparts which are commonly used in hospitals.…”

Enhanced acetone sensing properties based on in situ growth SnO2 nanotube arrays

“…Furthermore, acetone as a breath maker can also diagnose type-I diabetes [4][5][6]. It was found that the acetone level in diabetic patients' exhaled breath exceeds 1.8 ppm, whereas 0.35-0.85 ppm for healthy people [7,8]. To ensure the safety of the working and living environment and the convenience of medical detection, it is necessary to monitor acetone concentration by a rapid, convenient method [9].…”
