“…The hybridization of SARS‐CoV‐2's DNA–RNA that is used in RT‐PCR amplification can be induced by setting the temperature slightly lower than the melting temperature of the nucleic acid strand. [ 64 ] Qiu et al implemented this phenomenon to develop a dual‐functional gold nano island‐based biosensor by using thermos plasmonic heating (for signal amplification) and SPR imaging for the detection of RdRp, which is a closely related nucleic acid sequence of SARS‐CoV‐2, at a 0.22 pM detection limit. [ 65 ] At this concentration, a 200 μl of analyte solution contained ∼2.26 × 107 copies of the RdRp‐COVID sequence, which is higher than the viral load of the SARS‐CoV‐2 virus.…”

The review discusses the diagnostic application of biosensors as point‐of‐care devices in the COVID‐19 pandemic. Biosensors are important analytical tools that can be used for the robust and effective detection of infectious diseases in real‐time. In this current scenario, the utilization of smart, efficient biosensors for COVID‐19 detection is increasing and we have included a few smart biosensors such as smart and intelligent based biosensors, plasmonic biosensors, field effect transistor (FET) biosensors, smart optical biosensors, surface enhanced Raman scattering (SERS) biosensor, screen printed electrode (SPE)‐based biosensor, molecular imprinted polymer (MIP)‐based biosensor, MXene‐based biosensor and metal–organic frame smart sensor. Their significance as well as the benefits and drawbacks of each kind of smart sensor are mentioned in depth. Furthermore, we have compiled a list of various biosensors which have been developed across the globe for COVID‐19 and have shown promise as commercial detection devices. Significant challenges in the development of effective diagnostic methods are discussed and recommendations have been made for better diagnostic outcomes to manage the ongoing pandemic effectively.

“…When the doping weight ratio reached 30% and the sample is under electric field of 6 kV mm −1 , the maximum surface potential value can be reduced to almost 50% of its original value. Yang et al [95] reported a polymer nanocomposite composed of a dielectric polymer embedded with aligned core-shell structured nanowires for highly efficient distributed electrostatic discharge protection. The dielectric nanocomposite is capable of self-adaptive charge release, stemming from the nonlinear interface built in the Bi/Co oxide coated ZnO nanowires that leads to a 'hand-in-hand' double-Schottky barrier.…”

“…The alternating current (AC) electric field assist used in the composite preparation is able to modulate the filler distribution via dielectrophoresis [20,21], and favours the nonlinear conductivity characteristics [22]. For example, Ishibe et al revealed that, the AC electric field assist contributes to the ZnO microvaristor chains in epoxy resin matrix and to the superior nonlinear conductivity [23,24].…”

Nonlinear resistive field grading material presents nonlinear electrical conductivity, and self-homogenizes the electric field distribution. The nonlinear conductivity is closely associated to the filler distribution, which can be modulated by the electric field assist during the material preparation. In this paper, the effects of the direct current (DC) electric field assist on the filler distribution and nonlinear conductivity of the nonlinear resistive field grading materials were studied for the first time. The silicon carbide (SiC)/low-density polyethylene (LDPE) composites were prepared under different DC assisted electric field. The composites’ microstructure, dielectric spectra and DC conductivity were characterized, respectively. Results illustrate that the DC electric field assist leads to the gradient distribution of SiC filler in the matrix, and also contributes to the SiC particles’ chains. Compared with the untreated SiC/LDPE composite, the electric-field assisted composites show more distinct nonlinear conductivity characteristics when the DC assisted electric field exceeds 0.3 kV mm−1, which is attributed to the percolation phenomenon of SiC particles. This work is helpful to design the dielectric functionally graded materials, and to self-homogenize the electric field distribution in power apparatus and electronic devices.
