While replication is important in establishing scientific knowledge, novelty is typically regarded more highly when it comes to scientific publishing. In fact, the importance of originality is also reflected in the scope of ACS Sensors, which reads: “ACS Sensors is a peer-reviewed research journal that is devoted to the dissemination of new and original knowledge on all aspects of sensor science that

The fabrication of chemiresistive sensors by inkjet printing is recognized as a breakthrough in gas-sensing applications. One challenge of this technology, however, is how to enhance the cross-selectivity of the sensor array. Herein, we present a ketjen black (KB) ink and molecularly imprinted sol–gel (MISG) inks to support the fabrication of a fully inkjet-printed chemiresistive sensor array, enabling

In this study, Nb2Se9, a one-dimensional (1D) material with van der Waals (vdWs) bonding, was synthesized by chemical vapor deposition (CVD). A liquid precursor was used to overcome the difficulty of controlling the length and density of Nb2Se9 by CVD due to the high melting point of Nb. Growth proceeded horizontally in a nano-ribbon shape on the substrate in the [100] direction, which had the most

A novel electrochemiluminescence (ECL) biosensor for hyaluronidase (HAase) based on the adjustable electrostatic interaction between the surface-charge-controllable nanoparticles and negatively charged electrode has been devised. Hyaluronic acid (HA)-coated amino-modified ruthenium bipyridine-doped silica nanoparticles (Ru@SiO2–NH2@HA NPs) have been synthesized and act as ECL indicators, and the surface

Magnetism is a promising external intervention for gas sensitivity based on a heterogeneous interfacial structure caused by the regulation of the heterogeneous interface conductivity and the surface oxygen adsorption. In this study, Cu2O/NiO heterostructure-ordered nanoarrays were prepared with a two-dimensional (2D) electrodeposition in situ assembly method for H2S gas detection at room temperature

Detection and recognition of volatile organic compounds (VOCs) are crucial in many applications. While pure VOCs can be detected by various sensors, the discrimination of VOCs in mixtures, especially of similar molecules, is hindered by cross-sensitivities. Isomer identification in mixtures is even harder. Metal–organic frameworks (MOFs) with their well-defined, nanoporous, and versatile structures

Surface-enhanced Raman scattering (SERS)-encoded nanoparticles are used for bioimaging, on account of their well-defined Raman spectra and biocompatibility, which allow long incubation times with high signal stability and no cytotoxicity. However, reliable analysis of SERS bioimaging requires quantification of the amount of encoded nanoparticles that have been taken up by cells and the effect of subsequent

Personalized and point-of-care (POC) diagnoses are critical for ocular physiology and disease diagnosis. Real-time monitoring and continuous sampling abilities of tear fluid and user-friendliness have become the key characteristics for the applied ophthalmic techniques. Fluorescence technologies, as one of the most popular methods that can fulfill the requirements of clinical ophthalmic applications

One of the perks of being an Associate Editor for ACS Sensors is the chance to talk to the community through editorials. Often these highlight current trends or future opportunities for the field, but sometimes they provide an editor with a chance to grumble (many apologies, Justin). This month, I’d like to spend a couple of minutes talking about the use of the terms “sensitivity” and “limit of detection”

It is without question that Earth’s ecosystems must be monitored at adequate temporal and spatial resolution to make informed decisions about human disturbances, such as climate change, eutrophication, ocean oxygen depletion and acidification, and urban air pollution. Unfortunately, many critical parameters are currently not measured adequately because of limitations such as the associated high cost

Although there are many techniques to detect pathogenic bacteria, most of them are only suited for in vitro diagnostics. We report a urinary catheter-based colorimetric sensor for potential on-body detection of E. coli, the most prevalent bacterial species in urinary tract infections associated with the use of urinary catheters. In urine, indole is secreted by E. coli and reacts with a nitrosating

Affiliation 1 (associated with Pai-Chien Chou) should be changed from “Department of Thoracic Medicine, Taipei Medical University Hospital, Taipei, 106, Taiwan, Republic of China” to “Division of Pulmonary Medicine, Department of Internal Medicine, Taipei Medical University Hospital; Division of Thoracic Medicine, Department of Internal Medicine, School of Medicine, College of Medicine, Taipei Medical

The development of gas sensor technology continues to be an exciting area covered by ACS Sensors. Artificial intelligence (AI) is altering our society, and it is powered by the data. Gas sensors can translate multivariate biochemical information around us into data sources for this paradigm. Gas sensors enable us to track and see the invisible and instantaneous molecular information around us, so that
