Special Issue Information

Dear Colleagues,

With recent developments in material science, materials like Metal organic frameworks (MOFs), Covalent Organic Frameworks (COFs) have emerged as potential candidates for selective (bio-)chemical detection. Also, there have been significant developments in possible integration within semiconductor industry to enter in the field of portable devices.

This special issue aims to provide a platform to demonstrate the latest research and advancement in the field of (Bio-)chemical sensors from the perspective of porous materials. Both review articles and original research articles are invited with a focus on following fields:

  • Synthesis of porous materials as thin films/coatings
  • Integration of porous materials with semiconductor devices
  • Application of MOFs and COFs for Chemical and Biochemical Sensors
  • Porous materials-based sensors within sensor networks
  • Latest advancements in MOF/COF-based sensor minituarization
  • Sensor prototype developments

Humidity sensors with high sensitivity and fast response characteristics are of great interest for researchers. In this work, capacitive humidity sensors were fabricated using ionic liquid/cellulose nanofibers (CNFs) as the composited sensing film. The porous CNFs are beneficial for preparing sensing films via a solution process, and the ionic liquid could be uniformly dispersed in the films. The humidity-sensing performance of the as-prepared sensors was investigated. The optimized sensor showed a high response (27.95 pF/% RH) in a wide humidity range (11–95% RH) and a fast response speed in the adsorption process (the recovery time was only ~1 s). The high response of the sensors was attributed to the polarization at the interface between the electrolyte and the metal electrode, while the fast recovery was due to the rapid desorption of water molecules on the sensing films. Finally, the application of the obtained sensors in human breath monitoring was explored. Full article

Abstract
We leveraged chemical-induced changes to microwave signal propagation characteristics (i.e., S-parameters) to characterize the detection of aliphatic alcohol (methanol, ethanol, and 2-propanol) vapors using TCNQ-doped HKUST-1 metal-organic-framework films as the sensing material, at temperatures under 100 °C. We show that the sensitivity of [...] Read more.
We leveraged chemical-induced changes to microwave signal propagation characteristics (i.e., S-parameters) to characterize the detection of aliphatic alcohol (methanol, ethanol, and 2-propanol) vapors using TCNQ-doped HKUST-1 metal-organic-framework films as the sensing material, at temperatures under 100 °C. We show that the sensitivity of aliphatic alcohol detection depends on the oxidation potential of the analyte, and the impedance of the detection setup depends on the analyte-loading of the sensing medium. The microwaves-based detection technique can also afford new mechanistic insights into VOC detection, with surface-anchored metal-organic frameworks (SURMOFs), which is inaccessible with the traditional coulometric (i.e., resistance-based) measurements.

Metal-organic frameworks (MOFs) are emerging class of ordered porous materials consisting of metal clusters and organic ligands. High porosity, adjustable topology, composition and structural diversity have earned MOFs extensive popularity in various fields, including biosensing. This review focuses on understanding the role of MOFs in biosensing, mainly as efficient signal probes, nanozymes and nanocarriers. It also provides the recent advances of MOFs in sensing biomacromolecules such as protein, peptide, DNA, RNA and polysaccharide. In addition, the challenge, and perspectives, of MOFs in biosensing are presented, based on our opinion. Full article
