Exhaled breath acetone has been identified as a diabetes biomarker for non-invasive diagnosis. Its detection using biosensors features has many advantages over the conventional means. This paper reviews the recent literature on the detection of exhaled breath acetone and acetone vapor of diabetic interest. The biosensors have been classified based on their transduction methods. The performance characteristics of the biosensors have been explored for comparison. The future trends are also highlighted.

“…The 1588 cm −1 (from chitosan) and 1744 cm −1 (from GO) peaks were downshifted to 1565 and 1705 cm −1 , respectively, which indicated the formation of the new amide bond. In addition, the GO deformation vibration of NH 2 at 1420 cm −1 and the stretching vibration of CO at 1654 cm −1 (from chitosan) downshifted to 1403 and 1620 cm −1 , respectively, which also implied the network formation between chitosan and GO …”

“…The chitosan showed characteristic absorption peaks at (1654, 1588, 1420, 1380, 1156, and 1036) cm −1 for CO stretching, NH bending, NH deformation, CN stretching, COC stretching, and OH bending vibration, respectively . GO showed peaks at [1744, 1577, 1370, and (1151, 1048)] cm −1 for carbonyl CO stretching, the aromatic CC stretching, carboxyl CO symmetric stretching, and CO stretching vibration of the COC group, respectively . In the Chi–rGO network, the formation of amide bonding can be confirmed the shifts of characteristic peaks.…”

Although Li–S batteries are currently receiving great interest, due to their high energy density and the low cost of sulfur, practical applications are still inhibited by capacity fading that is caused by various undesirable processes. In this study, a new multifunctional network binder composed of chitosan and reduced graphene oxide (rGO) is introduced to enhance the capacitive performance of Li–S batteries. Chitosan is reacted with graphene oxide in aqueous solution to produce a homogenous network, which effectively enhances the redox system by entrapping lithium polysulfides, reinforces the mechanical properties, and allows electrical conductivity through the binder system. Collaborative relationship‐based chitosan–rGO network binder allows noteworthy improvement in the capacity decay of 0.016% per cycle at 1 C for 1000 cycles.

“…A GO and poly(styrene) composite was found to be sensitive to ammonia down to a few ppmv [181]. CGO/chitosan nanocomposites for amine vapors were reported by Zhang et al [182]. Sensitivity of 2-5 Hz/ppmv with Q-TSMR transducers, LDL below 3 ppmv and rather low cross-sensitivity to other VOCs would make these sensors appropriate for amine detection, but the large influence of background humidity is a real issue.…”
