“…After undergoing five consecutive cycles of the degradation process targeting MXB 5G dye, these NPs exhibited an impressive reusability efficiency rate of nearly 70 %. While this reusability efficiency might appear relatively lower compared to findings from earlier studies, it still stands as a commendable outcome [97] . It was reported that there was a drop in NPs activity from 95 % to 64 % as a result of five tests, as shown in Figure 7, as well as the interaction between AuNi@AC nano‐catalyst and MXB, leading to change in absorption peaks as depicted in Figure 7b.…”

The most essential task in the twenty‐first century is to fight the alarming growing pollution in the aquatic body in which effluent of one of the most colouring dye categories called maxilon dye is a major contributor. This review thus specifically focuses on the use of nanoparticles (NPs) for photocatalytic degradation of maxilon dye contaminants in water bodies. The work empirically presented the performance evaluation of NPs in degrading maxilon dyes under light irradiation alongside the underlying operational photocatalytic degradation mechanism. The stability of NPs was also critically analyzed by looking at the regenerability and reusability of expended NPs. From the study, it was discovered that ⋅OH and O2⋅ played a vital role in the genesis of the oxidizing capacity of NPs for the photocatalytic breakdown of maxilon dye. Moreover, it was found that the degradation performance of most NPs is greater than 80 % and the shortest degradation period is < 1 hour with pseudo‐first‐order (PFO) being the most common kinetic best‐fit to describe the adsorption process that occurred shortly before and during the degradation operation. At the end, knowledge gaps were identified in the area of regenerability, the lifecycle analyses of nano‐photocatalyst fabrication and utilization, cost analysis for industrial scale‐up, maxilon dye ecotoxicological study, and degradation pathways. The findings of this study can open up insightful innovation for readers and industries that are interested in pursuing zero water insecurity.

“…Nanosensors have an important role in various applications, such as imaging, drug delivery systems, molecular recognition, and phototherapy. Nanosensors play an important role in current sensing technologies and provide a deeper understanding of previously unexplored biological phenomena. − Fluorescent nanoparticles are particularly attractive for such tasks thanks to their emission signals, which can serve as an optical reporter for position or environmental properties. ,, SWCNTs are one-atom-thick graphene sheets of carbon atoms joined together to form a cylinder with a specific chirality and size that determine its physical, chemical, electronic, and optical properties. , As is known, carbon can be used in many different fields with its different allotropes. − SWCNTs exhibit outstanding mechanical, electrical, and optical properties, which are used in many fields such as materials science, electronics, sensors, etc. , Semiconductor SWCNTs are excellent signal transducers with stable and long lifetimes, giving bright fluorescence emission in the NIR region between 820 and 1600 nm, compared to organic molecules. , In addition, they do not bleach with light and are nonflashing. − Semiconductor SWCNTs have various sensor applications with their properties. In particular, SWCNTs in semiconductor structures constitute a new class of biosensors with various polymers .…”

Semiconducting single-walled carbon nanotubes (s-SWCNT) are structures that fluoresce in the near-infrared region. By coating SWCNT surfaces with polymeric materials such as single-chain DNA, changes in fluorescence emission occur in the presence of reagents. In this way, polymer-coated SWCNT structures allow them to be used as optical sensors for single molecule detection. Especially today, the inadequacy of the methods used in the detection of cellular molecules makes the early diagnosis of diseases such as cancer difficult at the singlemolecule level. In this study, the detection of nitric oxide (NO) signals, which are a marker of cancer, was carried out at the singlemolecule level. In this context, a sensor structure was formed by coating the 7,6-chiral s-SWCNT surface with ssDNA with different oligonucleotide lengths (AT). The sensor structure was characterized by using UV−vis spectroscopy and Raman spectroscopy microscopy. After formation of the sensor structure, a selectivity library was created using various molecules. As a result of the coating of the SWCNT (7,6) surface with DNA corona phase formation, Raman peaks at 195 and 276 cm −1 were observed to shift to the right. Additionally, the selectivity library results showed that the (AT)30 sequence can be used in NO detection. As a result of the studies using SWCNT (7.6)-(AT)30, the limit of detection (LOD) and limit of determination (LOQ) values of the sensor against NO were found to be 1.24 and 4.13 μM, respectively.

PdRuO2/PVP nanomaterial was synthesized using a straightforward method and characterized using advanced analytical methods such as TEM, XRD, XPS, elemental mapping and SEM. The synthesized PdRuO2/PVP nanomaterial was used as an ionophore in potentiometric sensor electrodes and successfully adapted to Cr3+ ion detection in a large number of aqueous samples. Several experimental parameters of the PdRuO2/PVP sensor such as potentiometric behavior, selectivity, repeatability, response time, pH, titration, and recovery in real samples were investigated. Potentiometric behavioral characteristics were performed in the concentration range 1 × 10−6–1.0 × 10−1 M. The repeated experiments performed six times showed that there was no deviation in the measurements. The limit of detection of the PdRuO2/PVP potentiometric sensor was very low with a value of 8.6 × 10−8 M. The potentiometric measurements showed that the synthesized PdRuO2/PVP ionophore was highly effective in detecting Cr3+ in a wide pH range of 2.0–8.0 and was found to have a shelf life of over 1 year. As a result, the synthesized PdRuO2/PVP electrode material was found to be highly selective, stable, and applicable for Cr3+ detection. Graphical Abstract
