“…These sensors offer notable advantages such as compact size, rapid response, and affordability in comparison to traditional instruments. Given the progress in nanofabrication technology and the emergence of novel sensing materials like carbon nanotubes, graphene, and black phosphorus (BP), the exploration of chemiresistive gas sensors remains a significant avenue of research [24]. Jae Eun Lee et al introduced a chemiresistive sensor based on a ZnO-CuO p-n heterojunction.…”

Non-biological analyte sensing refers to the ability to detect and quantify various chemical and physical parameters present in the environment or biological samples that are not directly associated with biological entities such as cells, tissues, or organisms. The field of non-biological analyte sensing has its roots in the early detection of any analytes, and over the years, it has expanded to include a wide range of applications such as environmental monitoring, food safety, and medical diagnostics. This perspective focuses on current status, challenges and future prospects of metal oxide nanostructures based non-biological analyte sensors. In this context, the present review aims to delve into the intricate mechanisms, fabrication techniques, and applications of printable chemical sensors for non-biological analytes. Through a comprehensive exploration of the scientific advancements and technological breakthroughs in this domain, this review seeks to provide a comprehensive understanding of the evolving landscape of printable chemical sensors and their pivotal role in modern analytical endeavours.

On-site detection of chemical warfare agents (CWAs) can be performed by various analytical techniques. Devices using well-established techniques such as ion mobility spectrometry, flame photometry, infrared and Raman spectroscopy or mass spectrometry (usually combined with gas chromatography) are quite complex and expensive to purchase and operate. For this reason, other solutions based on analytical techniques well suited to portable devices are still being sought. Analyzers based on simple semiconductor sensors may be a potential alternative to the currently used CWA field detectors. In sensors of this type, the conductivity of the semiconductor layer changes upon interaction with the analyte. Metal oxides (both in the form of polycrystalline powders and various nanostructures), organic semiconductors, carbon nanostructures, silicon and various composites that are a combination of these materials are used as a semiconductor material. The selectivity of a single oxide sensor can be adjusted to specific analytes within certain limits by using the appropriate semiconductor material and sensitizers. This review presents the current state of knowledge and achievements in the field of semiconductor sensors for CWA detection. The article describes the principles of operation of semiconductor sensors, discusses individual solutions used for CWA detection present in the scientific literature and makes a critical comparison of them. The prospects for the development and practical application of this analytical technique in CWA field analysis are also discussed.

Non-enzymatic Screen-Printed Chemiresistive Interdigitated Electrodes (SPCIE) were designed and fabricated using a low-cost screen-printing method for detection of the glucose. The Interdigitated Electrodes (IDE) pattern was printed using conductive graphene ink on the glossy surface of the photo paper. The proposed glossy photo paper-based SPCIE are functionalized with Multi-walled Carbon Nanotubes-Zinc Oxide (MWCNTs-ZnO) nanofibers to create the chemiresistive matrix. Further, to bind these nanofibers with the graphene electrode surface, we have used the green synthesized silver nanoparticles (AgNPs) with Banana Flower Stem Fluid (BFSF) as a binder solution. AgNPs with BFSF form the Conductive Porous Natural Binder Layer (CPNBL). It does not allow to increase the resistivity of the deposited material on graphene electrodes and also keeps the nanofibers intact with paper-based SPCIE. The synthesized material of MWCNT-ZnO nanofibers and green synthesized AgNPs with BFSF as a binder were characterized by Ultraviolet-visible spectroscopy (UV-Vis), Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and Fourier-Transform Infrared Spectroscopy (FTIR). The amperometric measurements were performed on the proposed SPCIE sensor to detect the glucose sample directly. The innovative paper-based SPCIE glucose sensor exhibits a linear corelation between current measurements and glucose concentration in the range between 45.22 µM – 20 mM, with a regression coefficient (R2) of 0.9902 and a lower Limit of Detection (LoD) of 45.22 µM (n=5). The sensitivity of the developed SPCIE sensor was 2178.57 µAmM-1cm-2, and the sensor's response time determined was approximately equal to 18 seconds. The proposed sensor was also tested for real blood serum sample, and Relative Standard Deviation (RSD) was found equal to 2.95%.
