Abstract Protein structure plays an essential role on their stability, functionality, and catalytic activity. In this work, the interplay between β ‐sheet its implications to design of enzyme‐inspired materials is investigated. Here, inspiration drawn from active sites rich highly efficient multicopper oxidase (MCO) engineer a bio‐inspired electrocatalyst for water oxidation utilizing abundant metal, copper. Copper ions are coordinated poly‐histidine (polyCuHis), as they in MCO sites. The...
The COVID-19 pandemic has highlighted the critical need for scalable, rapid, and cost-effective diagnostic solutions, especially in resource-limited settings. In this study, we developed a sustainable magnetic electrochemical biosensor mass testing of SARS-CoV-2, emphasizing affordability, environmental impact reduction, clinical applicability. By leveraging recycled materials from spent batteries plastics, achieved circular economy-based fabrication process with recyclability rate 98.5%....
SacCoMyo, an engineered artificial enzyme with a hydroxocobalamin core and protective heteropolysaccharide-linked shell, exhibits resilience in acidic electrolytes containing molecular oxygen, reducing the activation overpotential for hydrogen generation demonstrating high turnover frequency.
We report the study on formation of Cu2[Fe(CN)6] nanocomposite, which was obtained from copper oxide nanoparticles (CuO NPs) and Prussian Blue precursors. UV-vis analysis indicated that Cu2+ ions are released CuO NPs, while Fe3+ adsorbed onto structure due to a sharp increase in zeta potential (from -30 0 mV) after Cu2[Fe(CN)6]. Moreover, energy dispersive spectroscopy confirmed trapped NPs structure. The CuO/Cu2[Fe(CN)6] nanocomposite exhibited monoclinic face-centered cubic phases...

The ongoing COVID-19 pandemic continues to have a significant impact on our daily lives, necessitating the rapid development of early diagnostic tools mitigate emergence severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks. In this context, biosensor technology has emerged as highly promising strategy address challenges low sensitivity, specificity, and high cost associated with clinical diagnosis. study, we present novel cost-effective approach for detection SARS-CoV-2...
For a long time, the prevailing view in scientific community was that proteins, being complex macromolecules composed of amino acid chains linked by peptide bonds, adopt folded structure with insulating or semiconducting properties, high bandgaps. However, recent discoveries unexpectedly conductance levels, reaching values range dozens nanosiemens (nS) have challenged this conventional understanding. In study, we used scanning tunneling microscopy (STM) to explore single-entity properties...
