“…In respect to glucose sensing, Singh et al [228] successfully fabricated a flexible PET-based extended-gate FET sensor for pH monitoring which could detect the concentration of glucose simultaneously. A 40 nm sol-gel RuO x sensing membrane was deposited onto the ITO-coated PET substrates using the spin-coating process, as shown in Figure 12h.…”

The introduction of the "Internet of Things" (IoTs) concept has spawned a series of research and development of wearable sensors. Flexible field-effect transistors (FETs) are considered to be potential sensing devices due to the variety of material utilization and the self-amplifying function on electrical signals. FETs have demonstrated the ability of detecting different kinds of external stimuli and continuous monitoring functionalities. Herein, the recent progress achieved by the academia in wearable sensors based on flexible FETs, including pressure, temperature, chemical, and biological analytes, which are vital for the manufacturing of smart wearable devices, is summarized. The sensing mechanism for different sensors is introduced and an in-depth discussion is presented, including material engineering, problems at the current stage, and future challenges.

“…Another type of field-effect transistor (FET) technique, called extended-gate field-effect transistor (EGFET), was also used for super-Nernstian pH sensor; sol-gel ruthenium oxide (RuOx) as the pH sensitive sensing membrane was integrated as shown in Figure 5C [114]. Similar to the general FET system, the interaction between the transducer and electrolytes in the sample would cause the electric field on the surface of the sensor, changing the conductivity channel between source and Another type of field-effect transistor (FET) technique, called extended-gate field-effect transistor (EGFET), was also used for super-Nernstian pH sensor; sol-gel ruthenium oxide (RuOx) as the pH sensitive sensing membrane was integrated as shown in Figure 5C [114].

Personal biosensors and bioelectronics have been demonstrated for use in out-of-clinic biomedical devices. Such modern devices have the potential to transform traditional clinical analysis into a new approach, allowing patients or users to screen their own health or warning of diseases. Researchers aim to explore the opportunities of easy-to-wear and easy-to-carry sensors that would empower users to detect biomarkers, electrolytes, or pathogens at home in a rapid and easy way. This mobility would open the door for early diagnosis and personalized healthcare management to a wide audience. In this review, we focus on the recent progress made in modern electrochemical sensors, which holds promising potential to support point-of-care technologies. Key original research articles covered in this review are mainly experimental reports published from 2018 to 2020. Strategies for the detection of metabolites, ions, and viruses are updated in this article. The relevant challenges and opportunities of applying nanomaterials to support the fabrication of new electrochemical biosensors are also discussed. Finally, perspectives regarding potential benefits and current challenges of the technology are included. The growing area of personal biosensors is expected to push their application closer to a new phase of biomedical advancement.

“…The encapsulated GOX enzyme has been widely studied due to its considerable analytical and industrial applications (Blandino et al., 2001). In this sense, encapsulated GOX is extremely important for many biosensing applications as sensor arrays and matrices (Delfino et al., 2013; Singh et al., 2019), as an additive and antimicrobial in the food industry (Wong et al., 2008), and in bread‐making (Pescador‐Piedra et al., 2010). In addition to the above, GOX has wide applications in the textile industry because GOX is used to produce hydrogen peroxide for bleaching, from the upstream desizing and bioscouring processes (Tzanov et al., 2002).…”

The new consumer trends in food industry have promoted the use of nano-, micro-, and macroencapsulation technologies, looking to preserve active compounds from rapid oxidation or inactivation, such as enzymes. In this context, glucose oxidase (GOX) is widely used in various industrial processes and is considered an important green additive for the baking industry (Wong et al., 2008). However, one of the problems with free GOX is the enzyme's inherent instability and the decrease or loss of enzyme activity when the enzyme is subjected to thermal or chemical treatments during production, storage, and application.The encapsulated GOX enzyme has been widely studied due to its considerable analytical and industrial applications (Blandino et al., 2001). In this sense, encapsulated GOX is extremely important for many biosensing applications as sensor arrays and matrices
