Dual-Ionomer-Based Device: Acetylcholine Transport and Nonenzymatic Sensing

ACS Applied Materials & Interfaces (2020)

Nazrin Abdullayeva Alihan Kumtepe Çiğdem Tuç Altaf Hakan Seçkin Nurdan Demirci Sankır

The malfunctioning in the release of acetylcholine (ACh+), leading to consequential damages in the neural system, has become an impulsion for the development of numerous progressive transport and detection gadgets. However, several challenges, such as laterality and complexity of transport devices, low precision of amperometric detection systems, and sumptuous, multistaged enzymatic quantification methods, have not yet been overcome. Herein, ionomers, because of their selective ion transporting nature, are chosen as suitable candidates for being implemented into both targeted ACh+ delivery and sensing systems. Based on these two approaches, for the very first time in the literature, the disulfonated poly(arylene ether sulfone) membrane is concurrently (i) used in the mimicry of transduction of the electrical-to-ionic signal in a neural network as "Acetylcholine Pen" (ACh+ Pen) and (ii) operated as a highly sensitive, conductivity-based ACh+ quantifier. Our dual device, being able to operate under an actual action potential of 55 mVbias, shows a strong potential of future applicability in real-time ionic delivery-and-sensing systems.

Self-Powered Photoelectrochemical Photodetectors Based on a CsPbBr₃/S-g-C₃N₄ Heterojunction-Sensitized 3D ZnO Nanostructured Thin Film

ACS Applied Nano Materials (2024)

The production of photodetectors that can provide their own power needs and can be adapted to different application conditions is very important for next-generation optoelectronic devices. Three-dimensional (3D) ZnO in nanoflower (NF) morphology was synthesized to be sensitized with all-inorganic perovskite for the application of self-powered photodetector (PD) devices. Consequently, we report high-performance and air-/solvent-stable ZnO/CsPbBr3/S-g-C3N4-based PD devices in three different forms: as a solid-state form and photoelectrochemical (PEC)-type PDs in both liquid electrolyte systems and a quasi-solid-state (QSS) form. The solid-state configuration of the PD device generated a photocurrent density of 150 μA at 367 nm, while the detectivity and responsivity values were calculated as 3.4 × 1015 Jones and 0.25 AW–1, respectively. The device was confirmed to be air-stable upon stability tests for 90 days, retaining more than 65% of its initial current density. The self-power ability of ZnO/CsPbBr3/S-g-C3N4 PEC-type PDs was proven for both liquid electrolyte systems and QSS forms. Open cell voltage and sensitivity as high as 250 mV and 3.96 × 107%, respectively, were obtained for QSS ZnO/CsPbBr3/S-g-C3N4 PEC-type PDs. This study proved that the ZnO/CsPbBr3/S-g-C3N4-based PEC PD devices with high performance in the range of 367 to 460 nm can be adapted to meet different application requirements in a wide range from liquid electrolyte systems to solid- and QSS-type electrolyte systems.
