Flexibility and human-body compatibility have been emerged through the use of commercial fabrics (CFs) in designing wearable non-enzymatic glucose sensing platforms. In this work, electrodes fabricated through direct synthesis of ternary nickel–cobalt sulfide nanostructures (Ni-Co-S NSs) on the CFs (Ni-Co-S@CFs) using a fast and facile one-step microwave-assisted method for this purpose. Fabrication was followed by the structural and electrochemical characterization of the electrodes. The glucose-sensing ability of the prepared wearable electrodes was investigated via cyclic voltammetry (CV) and amperometry techniques in alkaline media. Two linear-responses in wide detection ranges of 0.04–2.3 and 2.31–9.91 mM with the sensitivities of 628.1 and 242.8 μA mM-1cm−2, respectively, together with a relatively low detection limit of 28.7 μM (based on S/N = 3) were obtained. Sensors showed high selectivity, acceptable repeatability, and long-term stability. The glucose level in human serum samples was further determined by employing the fabricated Ni-Co-S@CFs. Encouraging performance together with the flexible and foldable design make the fabricated sensing platforms immensely promising for wearable sensing applications.

Direct decoration of carbon nanohorns with binary nickel-cobalt sulfide nanosheets towards non-enzymatic glucose sensing in human fluids Kachouei, Matin Ataei; Hekmat, Farzaneh; Wang, Haolan; Amaratunga, Gehan A.J.; Ünalan, Hüsnü Emrah; Shahrokhian, Saeed (2022-10-01) A highly controllable, green, and rapid strategy is demonstrated for fabricating of highly sensitive non-enzymatic glucose sensing platforms. Carbon nanohorns (CNHs) were decorated onto the screen-printed electrodes. Binary nickel-cobalt sulfide (NiCo-S) nanosheets (NSs) were then deposited on CNH-casted electrodes by a facile and scalable method. Following detailed structural characterization and the electrocatalytic activity of the fabricated NiCo-S/CNH electrodes towards electro-oxidation of glucose was ...
Microwave-Assisted Synthesis of Stretchable and Transparent Poly(Ethyleneglycol-Sebacate) Elastomers with Autonomous Self-Healing and Capacitive Properties Gunal, Gulcin; Okan, Meltem; Gökcen, Dinçer; Çaykara, Tuncer; Aydın, Halil Murat (2020-06-01) Introducing functional synthetic biomaterials to the literature became quite essential in biomedical technologies. For the growth of novel biomedical engineering approaches, progressive functional properties as well as the robustness of the manufacturing processes are essential. By using acid-induced epoxide ring-opening polymerizations through catalysts, a wide variety of biodegradable and functionalized biomaterials can be synthesized. Sebacic acid (SA) and poly(ethylene glycol) diglycidyl ether (PEGDGE) ...
Sensitivity improvement strategies and applications for flexible and wearable capacitive pressure sensors Çiçek, Melih Ögeday; Ünalan, Hüsnü Emrah; Çınar, Simge; Department of Metallurgical and Materials Engineering (2022-8) Pressure sensors have attracted great interest in parallel with developments in wearable electronics, robotics, human-machine interface devices, and electronic skin. In this field, capacitive pressure sensors are gaining increasing research attention due to their high sensitivity, high stability, fast response/recovery times, and simple manufacturing routes. While capacitive pressure sensors have prominent features, there is still a long way to go before they become more common in wearable technology. Incre...
Cyber-physical-based PAT (CPbPAT) framework for Pharma 4.0 VATANKHAH BARENJI, REZA; Akdag, Yagmur; Yet, Barbaros; ÖNER, LEVENT (Elsevier BV, 2019-08-01) Industry 4.0 aims to integrate manufacturing operations into a seamless digital whole by incorporating flexibility, agility, re-configurability, and sustainability. The result of this integration is a "smart factory" that is more lean, agile, and flexible in operations. There are valid reasons, and perhaps requirements, for pharmaceutical industries to embrace smart factory and to "borrow" the concept of Industry 4.0 to give rise to "Pharma 4.0" (i.e., the pharmaceutical version of Industry 4.0). This paper...
Spray processable ambipolar benzotriazole bearing electrochromic polymers with multi-colored and transmissive states Hizalan, Goenuel; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Royal Society of Chemistry (RSC), 2011-01-01) In the context of low cost flexible display device technology, requirements can be fulfilled with accessible multi-colored electrochromic polymers. Here, we report the synthesis and electrochromic properties of two spray processable, ambipolar, fluorescent and multi-color to transmissive electrochromic polymers. Polymers, PTBTPh and PTBTTh, have multi-colored oxidation states and easily accessible n-doped states, which allowed us to achieve transmissive films in a low working potential. Electrochemical and ...
