Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides (TMDCs), and MXenes, have emerged as revolutionary platforms for developing next-generation sensors due to their exceptional electronic, optical, mechanical, and thermal properties. These atomically thin materials offer unprecedented flexibility in sensor device design across disciplines, spanning energy harvesting, sensing, nanoelectronics, and biomedical applications. The integration of 2D materials into novel architectures has enabled breakthroughs in performance, miniaturization, and multifunctionality, propelling innovations in smart sensing systems, wearable technologies, and beyond.

We are pleased to invite researchers and engineers to contribute original research articles, reviews, and perspectives to this Special Issue, which seeks to consolidate cutting-edge advancements and foster interdisciplinary collaborations in this dynamic field.

This Special Issue aims to highlight recent progress in the design, synthesis, characterization, and application of 2D-material-based sensor devices. By aligning with Sensors’ scope of publishing high-impact research on sensor technologies, materials science, and device engineering, this collection will emphasize how 2D materials enhance sensing capabilities, integration with hybrid systems, and scalable fabrication. Contributions should focus on overcoming current challenges—such as material synthesis reproducibility, interfacial engineering, and device stability—while demonstrating potential for real-world applications in healthcare, environmental monitoring, energy systems, and flexible electronics.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Sensor-oriented synthesis and characterization of 2D materials;
  • Photoelectric and optoelectronic sensors based on 2D materials;
  • MEMS sensors based on 2D materials;
  • Gas, chemical, and biosensors using 2D materials;
  • Flexible and wearable 2D material sensors for health and environmental monitoring;
  • Heterostructure engineering and surface functionalization for enhanced sensing;
  • Energy harvesting and self-powered sensing systems incorporating 2D materials;
  • Multiscale modeling, simulation, and AI-driven optimization of 2D material sensors.

Two-dimensional (2D) materials demonstrate significant potential in photodetector technology. They offer high sensitivity, wide spectral range, flexibility and transparency, especially in infrared detection, promising advancements in wearable and flexible electronics. This study explores the application of 2D materials in high-performance photodetectors. Rhenium diselenide (ReSe2) was used as the channel, and graphene (Gr) was inserted between ReSe2 and SiO2 as the gate electrode to enhance device performance. A ReSe2/Gr heterostructure field-effect transistor (FET) was fabricated to investigate the role of Gr in improving the optoelectronic properties of ReSe2 phototransistors. Specifically, the ReSe2 FET without Gr auxiliary layer demonstrates a responsivity (R) of 294 mA/W, an external quantum efficiency (EQE) of 68.75%, and response times as brief as 40/62 ms. Compared with the ReSe2 phototransistor, the ReSe2/Gr phototransistor exhibits significantly improved photoresponsivity and EQE, with the photoresponsivity enhanced by a factor of ap-proximately 3.58 and the EQE enhanced by a factor of approximately 3.59. These enhancements are mainly attributed to optimization of interfacial band alignment and the strengthened photogating effect by Gr auxiliary layer. This research not only underscores the pivotal role of Gr in boosting the capabilities of 2D photodetectors but also offers a viable strategy for developing high-performance photodetectors with 2D materials.

Graphene-based sensors and biosensors are attractive candidates for chemical and biological threat detection due to their high surface sensitivity, rapid transduction, and low-power operation, yet real-world deployment remains constrained by cross-sensitivity, interface instability in biosensing, and limited validation under operational conditions. This review consolidates key requirements for Chemical, Biological, Radiological, and Nuclear (CBRN) detection and proposes a structured roadmap to guide the transition from laboratory demonstrations to field-relevant sensing systems. The roadmap is explicitly modular and non-linear, integrating (i) qualitative research planning and gap analysis, (ii) computational screening via molecular docking as a hypothesis-generation tool with well-defined limitations, (iii) graphene electrode fabrication and functionalization using pulsed laser deposition (PLD) to enable tunable thickness/defect engineering and strong interface control, (iv) multiscale characterization combining laboratory methods with in situ/portable diagnostics, and (v) field-oriented performance evaluation focused on response time, stability, selectivity against industrial interferents, and false-positive/false-negative behavior. Iterative feedback loops connect all modules, enabling progressive refinement of material processing, recognition chemistry, and device architecture. By framing success in terms of technology-maturity progression and operational metrics, this roadmap provides a practical, defense-relevant framework for developing deployable graphene-based CBRN sensing platforms.
