“…This prompted Sakharov and co-workers to synthesize conductive, water-soluble SPS-polyaniline complexes using another oxidoreductase, laccase, which optimally catalyzed the reaction at pH 4.0–4.5 in the presence of molecular dioxygen. Since then, numerous other publications have emerged using oxidoreductases such as HRP, , laccase, glucose oxidase, , and others, , to catalyze the synthesis of π-conjugated polymers.…”

The integration of next-generation electronics into society is rapidly reshaping our daily interactions and lifestyles, revolutionizing communication and engagement with the world. Future electronics promise stimuli-responsive features and enhanced biocompatibility, such as skin-like health monitors and sensors embedded in food packaging, transforming healthcare and reducing food waste. Imparting degradability may reduce the adverse environmental impact of next-generation electronics and lead to opportunities for environmental and health monitoring. While advancements have been made in producing degradable materials for encapsulants, substrates, and dielectrics, the availability of degradable conducting and semiconducting materials remains restricted. π-Conjugated polymers are promising candidates for the development of degradable conductors or semiconductors due to the ability to tune their stimuli-responsiveness, biocompatibility, and mechanical durability. This perspective highlights three design considerations: the selection of π-conjugated monomers, synthetic coupling strategies, and degradation of π-conjugated polymers, for generating π-conjugated materials for degradable electronics. We describe the current challenges with monomeric design and present options to circumvent these issues by highlighting biobased π-conjugated compounds with known degradation pathways and stable monomers that allow for chemically recyclable polymers. Next, we present coupling strategies that are compatible for the synthesis of degradable π-conjugated polymers, including direct arylation polymerization and enzymatic polymerization. Lastly, we discuss various modes of depolymerization and characterization techniques to enhance our comprehension of potential degradation byproducts formed during polymer cleavage. Our perspective considers these three design parameters in parallel rather than independently while having a targeted application in mind to accelerate the discovery of next-generation high-performance πconjugated polymers for degradable organic electronics.

“…The efficient immobilization of laccase imparts a high direct bioelectrocatalytic activity of oxygen with a current density of 1.95 mA cm −2 . 96 In addition, Goff et al 97 covalently electrografted different types of aryldiazonium derivatives on CNT to aid the orientation of [NiFeSe]-hydrogenase. As a control, 1-pyrenebutyric acid adamantyl amide was used to non-covalently modify CNT via π–π stacking interactions (Fig.…”

“…To overcome the low reusability of free laccase, immobilization techniques have been employed to fix natural laccase onto carrier materials through adsorption, encapsulation, entrapment, covalent binding, cross-linking, and so on. − However, the immobilization process may cause irreversible effects on the enzyme activity, compromising activity of the laccase. Additionally, the high cost was also one of the drawbacks of laccase immobilization technology.…”

As a natural green catalyst, laccase has extensive application in the fields of environmental monitoring and pollutant degradation. However, susceptibility to environmental influences and poor reusability seriously hinder its application. To address these concerns, for the first time, manganese ion replaced copper ion as the active center to coordinate with guanosine monophosphate (GMP) for synthesizing mimic laccase with high catalytic activity. Compared with natural laccase, the laccase-like nanozyme (Mn− GMPNS) demonstrated superior thermal stability, acid−base resistance, salt tolerance, reusability, and substrate universality. Benefiting from the high catalytic activity of Mn−GMPNS, epinephrine, a significant neurotransmitter and hormone associated with numerous diseases, was visually detected within 10 min and a portable assay by smartphone. More encouragingly, Mn−GMPNS can efficiently degrade dye pollutants, achieving a decolorization rate over 70% within 30 min. Thus, the coordination between manganese ion and nucleotide demonstrated the potential in rational design of nanozymes with high catalytic activity, low cost, good stability, and good biocompatibility.
