“…Most of the time the cross-linking agent glutaraldehyde is used in the covalent type of immobilization used in biosensors (Table 1). Cevher et al, 2021 reported the immobilization of the laccase on a PM1 electropolymer surface by covalent linkage via glutaraldehyde [66]. This biosensor was successfully applied for the stable detection of the indenoquinoxalinone from water.…”

Monitoring phenolic compounds is critical in the environmental, food, and medical sectors. Among many recent advanced detection platforms, laccase-based biosensing platforms gave very rapid, effective, online, and in situ sensing of phenolic compounds. In laccase-based biosensors, laccase immobilization techniques have a vital role. However, a detailing of the advancements in laccase immobilization techniques employed in laccase-based biosensors is lacking in the literature. Thus, in this review, we assessed how the nano-immobilization techniques shaped the laccase biosensing platforms. We discussed novel developments in laccase immobilization techniques such as entrapment, adsorption, cross-linking, and covalent over new nanocomposites in laccase biosensors. We made a comprehensive assessment based on the current literature for future perspectives of nano-immobilized laccase biosensors. We found the important key areas toward which future laccase biosensor research seems to be heading. These include 1. A focus on the development of multi-layer laccase over electrode surface, 2. The need to utilize more covalent immobilization routes, as they change the laccase specificity toward phenolic compounds, 3. The advancement in polymeric matrices with electroconductive properties, and 4. novel entrapment techniques like biomineralization using laccase molecules. Thus, in this review, we provided a detailed account of immobilization in laccase biosensors and their feasibility in the future for the development of highly specific laccase biosensors in industrial, medicinal, food, and environmental applications.

Impact of macro molecular theory on the progress of sensing sciences and technology has been presented in the light of materials developments, advances in physical and chemical properties. The chronological advances in the properties of macromolecules have significantly improved the sensing performances towards gases, heavy metals, biomolecules, hydrocarbon, and energetic compounds in terms of unexplored sensing parameters, durability, and working lifetime. In this review article, efforts have been made to correlate the advances in structure and interactivity of macro-molecules with their sensing behavior and working performances. The significant findings on the macromolecules towards advancing the sensing sciences are highlighted with the suitable illustration and schemes to establish it as a potential “microanalytical technique” along with existing challenges.

Two alternating copolymers bearing fluorinated benzothiadiazole as a strong acceptor unit and dithienopyrrole as a strong donor unit were designed and synthesized to investigate the effect of the number of fluorine atoms substitution. The polymers were characterized via cyclic voltammetry, spectroelectrochemistry, electrochemical impedance spectroscopy and galvanostatic charge discharge studies. Besides a red shift in absorption spectra, an anodic shift was also observed in the oxidation potentials when number of fluorine atom increases in the polymer backbone. Galvanostatic charge discharge studies revealed that difluorinated polymer showed enhanced area specific capacitance compared to mono fluorinated polymer.
