Special Issue Information

Dear Colleagues,

We are planning to publish a Special Issue, entitled as “State-of-the–Art Chemical Sensors in Korea”. With the recent development of Korea's 4th industry along with the advent of the IoT era, research on a variety of sensors has been very active, making significant progress. In particular, chemical sensors are becoming core technologies of future society, because the detection of gases, ions, and liquids is important for monitoring various phenomena and maintaining human health. As a result, Korean researchers in universities and research institutes are publishing world-level research achievements. Accordingly, it will be very urgent and useful to collect recent researches in Korea and understand the research trends of chemical sensors. The goal of this Special Issue is to invite high-quality, state-of-the-art research papers that deal with issues which are directly or indirectly related to chemical sensors in a broad sense. We invite to submit unpublished original papers. Topics of interest include, but are not limited to, the following:

  • Gas sensors
  • Metal oxide/2D materials/carbon-based sensors
  • Nano sensors
  • Ion sensor/ water sensors
  • Liquid sensors
  • Chemical sensors
  • Electrochemical sensors
  • Optical chemical sensors
  • Wearable chemical sensors
  • Flexible sensors
  • Chemical sensors for diagnostics/health
  • Olfaction/Electronic nose
  • Sensors fundamentals
  • Sensor devices and systems
  • Advanced materials and nanotechnology Applications
  • Sensing mechanisms/basic understandings

Herein, state-of-the-art research advances in South Korea regarding the development of chemical sensing materials and fully integrated Internet of Things (IoT) sensing platforms were comprehensively reviewed for verifying the applicability of such sensing systems in point-of-care testing (POCT). Various organic/inorganic nanomaterials were synthesized and characterized to understand their fundamental chemical sensing mechanisms upon exposure to target analytes. Moreover, the applicability of nanomaterials integrated with IoT-based signal transducers for the real-time and on-site analysis of chemical species was verified. In this review, we focused on the development of noble nanostructures and signal transduction techniques for use in IoT sensing platforms, and based on their applications, such systems were classified into gas sensors, ion sensors, and biosensors. A future perspective for the development of chemical sensors was discussed for application to next-generation POCT systems that facilitate rapid and multiplexed screening of various analytes.

This review presents the results of cutting-edge research on chemiresistive gas sensors in Korea with a focus on the research activities of the laboratories of Professors Sang Sub Kim and Hyoun Woo Kim. The advances in the synthesis techniques and various strategies to enhance the gas-sensing performances of metal-oxide-, sulfide-, and polymer-based nanomaterials are described. In particular, the gas-sensing characteristics of different types of sensors reported in recent years, including core–shell, self-heated, irradiated, flexible, Si-based, glass, and metal–organic framework sensors, have been reviewed. The most crucial achievements include the optimization of shell thickness in core–shell gas sensors, decrease in applied voltage in self-heated gas sensors to less than 5 V, optimization of irradiation dose to achieve the highest response to gases, and the design of selective and highly flexible gas sensors-based WS2 nanosheets. The underlying sensing mechanisms are discussed in detail. In summary, this review provides an overview of the chemiresistive gas-sensing research activities led by the corresponding authors of this manuscript. Full article

Taste sensors can identify various tastes, including saltiness, bitterness, sweetness, sourness, and umami, and have been useful in the food and beverage industry. Metal–organic frameworks (MOFs) and MXenes have recently received considerable attention for the fabrication of high-performance biosensors owing to their large surface area, high ion transfer ability, adjustable chemical structure. Notably, MOFs with large surface areas, tunable chemical structures, and high stability have been explored in various applications, whereas MXenes with good conductivity, excellent ion-transport characteristics, and ease of modification have exhibited great potential in biochemical sensing. This review first outlines the importance of taste sensors, their operation mechanism, and measuring methods in sensing utilization. Then, recent studies focusing on MOFs and MXenes for the detection of different tastes are discussed. Finally, future directions for biomimetic tongues based on MOFs and MXenes are discussed.
