Special Issue Information

Dear Colleagues,

Currently, advanced technologies and new forms of industry are blooming and improving our daily lives. We are living in the era of a “SMART WORLD”, where the Internet of Things (IoT) is becoming the next technological revolution. The heart of the IOT is data acquisition through various probes using distinct techniques. The capacity of a device to see (photonics), feel (pressure/motion), smell (electronic noses), hear (ultrasonic), think/communicate (smart electronics and wireless), and move (sensors integrated with actuators) is rapidly advancing, indicating optimistic prospects for sensors. To achieve the potential of omnipresent sensing systems that provide real-time information at a cheap cost, a tangible outcome must be obtained, which can only be achieved through further functional material development.

Due to the abundance of carbon materials in nature, a novel device based on 1D, 2D, and 3D carbon-based materials is particularly appealing. These materials' diverse structural compositions provide a number of novel physicochemical properties, rendering them ideal choices for sensing applications. However, one must tailor their physicochemical characteristics for a specific functional application without compromising performance. In this context, numerous carbon-based sensor materials have been developed to date via functionalization, heteroatom doping, molecular engineering, interlayer chemistry, and so on. New gadgets are also being developed that are based on optical, luminescence, fluorescence, surface plasmon, electrochemical, colorimetry, and polarization phenomena. Though the available works address a wide range of sensing applications, there is a lack of understanding about commercialization and practicality. Therefore, this issue invites manuscripts that address issues related to sensing of healthcare-related biomolecules (biomarkers for crucial diseases), environmental hazard chemical species (heavy metal ions, carcinogenic molecule, organic pollutants, and gases), industrial manufacturing (pressure, pulses, and motion), Food (microbes, trace elements, and organic molecules), pharmaceutical (drug molecules), etc.

The potential topics include, but are not limited to, the following:

  • Development of compact/wearable/self-powered bio/gas/pollutant sensors;
  • New strategies to tune the electronic/surface characteristics of 1D, 2D, and 3D carbon materials for sensing applications;
  • Development of invasive/non-invasive biosensors;
  • Synthesis and fabrication of novel carbon-based sensing materials;
  • Motion/pressure sensors;
  • Portable/smartphone-assisted sensors.

The conversion of metal-organic frameworks (MOFs) into advanced functional materials offers a promising route for producing unique nanomaterials. MOF-derived systems have the potential to overcome the drawbacks of MOFs, such as low electrical conductivity and poor structural stability, which have hindered their real-world applications in certain cases. In this study, laser scribing was used for pyrolysis of a Cu-based MOF ([Cu4{1,4-C6H4(COO)2}3(4,4′-bipy)2]n) to synthesize a Cu-CuO@C composite on the surface of a screen-printed electrode (SPE). Scanning electron microscopy, X-ray diffractometry, and Energy-dispersive X-ray spectroscopy were used for the investigation of the morphology and composition of the fabricated electrodes. The electrochemical properties of Cu-CuO@C/SPE were studied by cyclic voltammetry and differential pulse voltammetry. The proposed flexible electrochemical Cu-CuO@C/SPE sensor for the simultaneous detection of hydroquinone and catechol exhibited good sensitivity, broad linear range (1–500 μM), and low limits of detection (0.39 μM for HQ and 0.056 μM for CT).
