This sensor was created by utilizing a platinum on laser-induced graphene (Pt/LIG) structure. The synthesis process involves the creation of highly crystalline graphene with a large surface area, which serves as an optimal support for nanosized pt catalysts. Post-synthesized Pt nanoparticles were dispersed on the surface of the LIG electrode and envisaged for the hydrogen gas sensing property under ambient conditions without a heating or sensor device. Analysis showed that the Pt nanoparticles are uniquely characterized by their narrow size distribution of less than 5 nm and their homogeneous deposition on the LIG substrate, which itself exhibits a substantial specific surface area of 187.4 m²/g. This configuration enables the sensor to achieve a very low limit for detection of hydrogen to 200 ppb. Moreover, the sensor demonstrates exceptional performance attributes, including high sensitivity, excellent linearity, and remarkable cycle stability over 50 cycles. The synergy between the high surface area of the LIG and the catalytic activity of the Pt nanoparticles facilitates the detection of hydrogen at room temperature.

Their persistence and potential to adsorb heavy metals raise significant concerns regarding water quality and ecosystem health. Understanding the interaction between MPs and heavy metals is crucial for assessing environmental risks and developing remediation strategies. In this study, we use electroanalytical techniques to investigate the adsorption of heavy metal ions— Cr³⁺, Zn²⁺, and Ni²⁺—by polystyrene MPs with different surface functionalizations: carboxyl, amino, and unfunctionalized. We conducted electrodeposition of metal ions on a gold ultramicroelectrode both before and after mixing with MPs. Following this, we used anodic stripping voltammetry to measure the change in the electrodeposited charge (ΔQ). This charge difference, observed before and after the interaction of ions with MPs, was analyzed to understand the adsorption kinetics and dynamics. Our experiments revealed that carboxyl-functionalized MPs exhibited the highest ΔQ due to strong electrostatic attraction with the metal ions, with values 1.67 ×, 1.50 ×, and 1.22 × greater than those for amino-MPs for Cr³⁺, Zn²⁺, and Ni²⁺, respectively. Amino-MPs displayed considerable ion adsorption, suggesting poor electrostatic repulsion between two positively charged entities. Interestingly, unfunctionalized MPs, which had a negative surface charge similar to carboxyl-MPs, showed different adsorption characteristics, with lower ΔQ values for all metal ions. This study underscores the significant role of surface functionalization on the adsorption efficiency and kinetics of heavy metal ions by MPs. It also demonstrates the utility of electroanalytical techniques in understanding metal ion-MP interactions, offering insights into potential environmental impacts and remediation strategies, as well as in developing electrochemical sensors for detecting heavy metal ions adsorbed on MPs.</p></div>","PeriodicalId":426,"journal":{"name":"Sensors and Actuators Reports","volume":"8 ","pages":"Article 100241"},"PeriodicalIF":6.5,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666053924000572/pdfft?md5=404d6c1773b095ba571af67154ce15a6&pid=1-s2.0-S2666053924000572-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142147966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methyl viologen (MV) is commonly employed as a redox mediator and electron acceptor, exhibiting three distinct redox states (MV⁰, MV⁺, and MV²⁺), each characterized by a unique molecular structure and Raman spectrum. Utilizing surface-enhanced Raman spectroscopy (SERS), we explore the discrete molecular redox states of MV on shell-isolated nanoparticles (SHINs), which are gold nanoparticles (AuNPs) coated with silica shells of varying thicknesses, ranging from 1 to 10 nm. Our study, employing 532 nm excitation, reveals that all three redox forms of MV are sporadically observed on the metallic surfaces of AuNPs. However, the radical cation (MV⁺) state is predominantly detected on the silica surfaces of the SHINs, irrespective of the shell thickness. This consistency across different shell thicknesses suggests that electromagnetic (EM) effect predominantly contributes to the Raman enhancement in shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), rather than enhancement via electron transfer. If electron transfer were induced by laser excitation, varying redox species would likely appear dependent on shell thickness. Given the absence of external perturbation such as applied potential or reducing agents, we believe our findings can provide a crucial reference for future studies using MV as a redox state-sensing probe.
