Special Issue Information

Dear Colleagues,

Recent progress in bio- and chemical-sensor technology has been closely linked to the development of new materials and fabrication methods. A wide range of functional materials—including emerging two-dimensional structures, metal–organic frameworks, engineered polymers, and biomimetic components—has opened up new possibilities for improving sensitivity, selectivity, and operational stability. At the same time, advances in micro- and nanofabrication, additive manufacturing, soft-patterning techniques, and flexible device construction are broadening the range of environments in which sensors can be deployed, from wearable and portable systems to environmental analysis and point-of-care testing.

This Special Issue, ‘Multi-Dimensional Nanomaterials for Biological and Chemical Sensors’, seeks contributions that reflect the continuing evolution of this field. We invite original research and reviews that introduce new sensing materials, explore fabrication or integration strategies, or demonstrate sensor platforms with enhanced performance or new functional features. Work that clarifies material–analyte interactions, improves transduction pathways, or addresses challenges in device assembly and system integration is also encouraged.

By assembling perspectives from materials science, chemistry, engineering, and related disciplines, this Special Issue aims to showcase advances that will shape the next generation of sensing technologies for medicine, environmental protection, and industrial applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The aim of this study was to investigate the impact of ZnO nanoparticles on the humidity-sensing properties of BiFeO3 nanoparticles. BFO, ZnO, and x% ZnO-BiFeO3 nanoparticles were synthesized using chemical processes and then analyzed by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), and Raman spectroscopy. The electrical capacitance of the sensors was measured using an impedance meter over a Relative Humidity (RH) range of 17 to 94% at room temperature and at an applied frequency of 100 Hz. This paper demonstrates that adding zinc oxide (ZnO) to bismuth ferrite (BFO) materials significantly improves the humidity response of BFO-based sensors. Indeed, a response of 2.8 × 106% was achieved for 20% ZnO-BFO-based sensors, compared with 5.8 × 103% for a pure BFO-based sensor. At the same time, a low hysteresis effect and excellent long-term stability were observed. In conclusion, the addition of ZnO nanoparticles provides excellent humidity-sensing properties to the BFO material, thereby contributing to its wide range of applications. Full article
