Recently, flexible electrochemical biosensors have been attracting more and more attentions throughout the world both in academia and industry, because of its leading role in the development of efficient, miniaturized, rapid and user-friendly device towards health monitoring, environmental microsense systems and defense systems. Herein, we shine a light on the advances in flexible electrochemical biosensors by tracking the developments of novel carbon nanomaterials based smart device design and versatile applications. Particularly, the flexible electrochemical biosensors either with supported substrates or free-standing are summarized. We start from retrospection on the outlook of the field and highlight the direction of flexible electrochemical biosensors in the areas of healthcare, security and environmental monitoring. And then we review the recently developed fabrication approaches with discussing the state-of-art findings for each category. It is believed that the flexible electrochemical biosensors will play a more and more pivotal role in the emergent body sensor networks arena with the fast development of carbon nanomaterials and smart devices design.

“…Currently, most commercial glucose monitoring sensors are enzyme-based devices, such as glucose oxidase and glucose dehydrogenase, relying on electrochemical analytical measurements. Despite the good selectivity and sensitivity toward glucose, enzyme-based strategies have some drawbacks, especially for continuous glucose monitoring, such as inflated cost, thermal and chemical instability, and strict storage conditions [ 8 , 9 ]. Enzyme-based sensors require complex enzyme fixation processes to maintain enzyme activity, and the commercialized manufacture of enzyme-based devices requires sterilization of the entire production line [ 10 ].…”

Non-enzymatic sensors with the capability of long-term stability and low cost are promising in glucose monitoring applications. Boronic acid (BA) derivatives offer a reversible and covalent binding mechanism for glucose recognition, which enables continuous glucose monitoring and responsive insulin release. To improve selectivity to glucose, a diboronic acid (DBA) structure design has been explored and has become a hot research topic for real-time glucose sensing in recent decades. This paper reviews the glucose recognition mechanism of boronic acids and discusses different glucose sensing strategies based on DBA-derivatives-based sensors reported in the past 10 years. The tunable pKa, electron-withdrawing properties, and modifiable group of phenylboronic acids were explored to develop various sensing strategies, including optical, electrochemical, and other methods. However, compared to the numerous monoboronic acid molecules and methods developed for glucose monitoring, the diversity of DBA molecules and applied sensing strategies remains limited. The challenges and opportunities are also highlighted for the future of glucose sensing strategies, which need to consider practicability, advanced medical equipment fitment, patient compliance, as well as better selectivity and tolerance to interferences.

Our recent studies have demonstrated that SWCNT electrodes have strong electrocatalytic activity when modified with metal 2017 © The Japan Society for Analytical Chemistry † To whom correspondence should be addressed. In the present study, we developed an electrochemical sensor for highly sensitive detection of hydroxylamine using Au-Pt alloy nanoparticles. Au-Pt alloy nanoparticles were electrochemically deposited on a working electrode made of singlewalled carbon nanotubes. The framework composition in the Au-Pt alloy nanoparticle was easily controlled by adjusting the Au 3+ :Pt 4+ composition ratio in the precursor solution. Morphological and chemical characterizations of the resulting Au-Pt alloy nanoparticles were performed using field emission scanning electron microscopy, X-ray diffraction, and energy dispersion X-ray spectroscopy. When the Au 3+ :Pt 4+ ratio in the precursor solution was 1:5, the ratio of Au:Pt atom in alloy nanoparticle was about 6:4. Au60Pt40 alloy nanoparticles were found to have the optimum synthetic ratio for hydroxylamine detection. The electrocatalytic performance of Au-Pt alloy nanoparticles in the presence of hydroxylamine was also characterized using cyclic voltammetry, differential pulse voltammetry, and chronoamperometry. In the chronoamperometric detection of hydroxylamine, the sensor exhibited a detection limit of 0.80 μM (S/N = 3) and a high sensitivity of 184 μA mM -1 cm -2 . Moreover, the amperometric response of the sensor in 1 mM hydroxylamine was stable for a long time (450 s). Long-term stability tests showed that the current responses to hydroxylamine were 96, 91 and 85% of the initial signal value after storage for 5, 10, and 20 days, respectively.
