Abstract Conductive hydrogels are becoming one of the most important milestones for development new scaffolds, biosensors, supercapacitors, and green electronics within field biomedicine. In this work, we study effect different types electroactive additives such as poly(3,4-ethylenedioxythiophene), tannic acid, carbon quantum dots (CQDs), to form poly(vinyl alcohol) (PVA)-based with enhanced electrochemical properties. Different physicochemical tests carried out characterize PVA-based hybrid rates their degradation loss electroactivity throughout an eight-week biodegradation process. This work shows individual synergistic effects on various mechanical properties, including storage modulus swelling ratio, properties PVA hydrogel. The have proven enhance but well degradation. Finally, use hydrogel a pressure sensor is also investigated. provides insight potential CQDs, in synergy other enhancers, fabrication novel conducting electronics. Graphical

In this study, we report a novel sensing platform based on used liquid crystal display (LCD) as working electrode in electrochemical applications. This paves the way for sustainable recycling of e-waste and cost-effective approach development electrodes. Here, discarded LCD was modified with Ti3C2Tx MXene detection dopamine (DA). Cyclic voltammetry studies revealed that Ti3C2Tx-modified shows better enhancement sensor response compared bare LCD. The developed able to detect DA from 10 nM 100 μM limit about 4.5 nM. Additionally, also very high selectivity, stability, repeatability towards DA. practical applicability is evaluated by detecting form human serum samples. We have tested different panels manufacturers found all LCDs are minor changes current response. To best our knowledge, possibility using scrap screens applications has not been reported date. Using materials electrodes will be both approach. innovation provides an economical solution managing or reducing increasing amount generated environment. Hence, reusing disposed open up new avenues toward methods upcycling hazardous e-waste.

The present study reported the synthesis of three CuX/S-doped g-C3N4 nanocomposites (CuX= CuO/CuS/Cu2O) via an efficient and simple approach. various prepared were characterized with different characterization techniques demonstrated pure nanocomposites. Among nanocomposites, CuS/S-doped exhibits a remarkable electrochemical performance for detecting dopamine (DA). Herein, parameters, such as volume electrocatalyst used solution's pH, optimized to achieve detection. Under favorable conditions, effective response DA detection using linear sweep voltammetry (LSV) cyclic (CV) methods. proposed sensor afforded plot between anodic peak current concentration in range 0–200 μM low limit (0.1227 or 122.7 nM) current. In addition, constructed displayed satisfactory stability reproducibility. real sample, i.e., human serum, was employed assess ability perform real-time analysis sensing platform. developed recovery rate, illustrating its practical functionality.
