Till date, no systematic review is conducted on electrochemical biosensing of multiplexed breast cancer miRNAs to identify their suitability as an alternative diagnostic tool for ductal carcinoma in situ (DCIS). Original articles published in English from PUBMED, Science Direct, Scopus, MEDLINE, Cochrane Library, National Centre for Biotechnology Information, and Google scholar during Jan 2012–Feb 2022 were searched using set inclusion criteria. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) 2020 guidelines was followed to report this review. Methodological quality of the included studies was evaluated using Risk of Bias (ROB) assessment criteria. Out of 1973 screened articles, 17 studies were eligible and included in this review wherein, 1 study (5.88%) involving generic neutravidin modified nanolabel probe using biotintylated molecular beacons immobilized metal nanoparticles prepared using one pot assay to detect miRNAs 21 and 141 had low ROB and 16 studies (94.12%) had medium ROB. Medium ROB of majority of the included studies reveals its limited evidence to conclude its suitability for diagnosing DCIS using miRNAs. High quality studies with inter assays and validation are extensively needed for the development of diagnostic tool for DCIS via miRNAs.

As heat engines, thermoelectric converters can utilize a large amount of free low-grade thermal energy in the environment to generate electricity cleanly and quietly, contributing to a sustainable low-carbon life. They can also act as refrigerators and sensors based on their special ability to reversibly convert heat to electricity. Attractively, thermoelectric converters fabricated by microelectromechanical system technology exhibit more powerful potential when reaching the micro/nano-scale owing to the characteristics of electrons and phonons transport, with cost-effective mass manufacturing advantages. Thermoelectric converters will play an increasingly important role in extensive fields with a bright future.

Cavitas sensors and point-of-need sensors capable of providing physical and biochemical information from the oral cavity and saliva have attracted great attention because they offer remarkable advantages for noninvasive sensing systems. Herein, we introduce the basic anatomy and physiology of important body cavities to understand their characteristics as it is a pivotal foundation for the successful development of in-mouth devices. Next, the advanced development in lab-in-a-mouth sensors and point-of-need sensors for analyzing saliva are explained. In addition, we discuss the integrations of artificial intelligence and electronic technologies in smart sensing networks for healthcare systems. This review ends with a discussion of the challenges, future research trends, and opportunities in relevant disciplines. Mouthguard-based sensors and conventional salivary sensing devices will continue to be significant for the progress in the next-generation sensing technologies and smart healthcare systems.

A novel method of integration of a silver-polydimethylsiloxane (PDMS) nanocomposite in a microfluidic channel for the realization of a lab-on-a-chip is reported in this work. By using a silver nitrate aqueous precursor solution, silver nanostructures are formed on, and under the surface of PDMS, by in situ reduction. The silver aggregates formed by reduction have a wide absorbance plasmon band in the UV–Visible range. Separated silver nano-islands, having narrow absorbance bands are formed by using the post-reduction annealing process. The plasmonic property of the silver nanostructures is used for the detection of bovine growth hormone. Subsequently, the nanocomposite was integrated into a specially fabricated micro-wall in the channel which is the actual sensing area in the microfluidic environment. The experiments confirmed that the nanocomposite can be integrated into the microfluidic device in order to enhance the detection sensitivity.

Portability is one of the essential keys in the development of modern analytical devices. Screen printing technology is an established technology for both chemical and biosensor development. Screen printing technology has been used to generate a variety of electronic sensors that are rapid, cost-effective, on-site, real-time, inexpensive, and practical for use in healthcare, environmental monitoring, industrial monitoring, and agricultural monitoring. This review aims to describe recent research progress related to the development and improvement of screen-printed electrodes (SPEs). We also demonstrate the wide range of applications, also highlighting the market directions and the need for novel devices to be used by non-specialists. Finally, we conclude and provide an overview of the constraints and future opportunities of SPEs in biosensor application.

This study investigates the use of DC sputtering, physical vapor deposition as a facile method for creating ultralow loading, Au/C electrodes for use in the detection of As (III) in water. The sputtered nanofilm electrodes on carbon papers, substantially reduces the amount of Au consumed per electrode, <10 μg cm−2, compared to use of wire, foil, or screen-printed electrodes. Linear stripping voltammetry (LSV) was chosen for analytical simplicity and ease of automation. Electrodes using Au nanoparticles supported on Vulcan XC 72 R carbon were also investigated but were not viable for LSV analysis due to capacitive current charging of the high surface area carbon. The DC sputtered, Au nanofilm electrodes were used to create calibration curves for concentrations of As (III) between 5 and 50 μg l−1 and the standard addition method was used in a surface water sample with 5.5 μg l−1 total As. Peak areas plotted against concentration displayed strong linear correlation with meaningful detection below the USEPA maximum contaminant level (MCL) of 10 μg l−1. To our knowledge, this is the first study which utilizes the facile and mass manufacturable DC sputtering method to produce As (III) sensing electrodes. The results of this study have implications for the development of single use, low-cost nanofilm electrodes for field As (III) electroanalysis.

Multiplex biomarker quantitation is ideal for tracking the progression of a disease, but sensitive, specific, and quantitative multiplex biosensing remains challenging. We achieved total internal reflection with two lasers in a single planar optical waveguide by coupling 532 nm laser light into the diffraction grating of a waveguide and 635 nm laser light directly into the thin film of the same waveguide. We confirmed that the evanescent fields generated in the waveguide can excite two fluorescent dyes (Alexa Fluor 532 and Alexa Fluor 647) held to the surface of the waveguide through biotin-streptavidin chemistry. This sensing concept holds significant potential as a platform for multiplex biomarker detection.
