Since 2004, we have been developing nanomaterials with antimicrobial properties, the so-called nanoantimicrobials. When coronavirus disease 2019 (COVID-19) emerged, started investigating new and challenging routes to nanoantivirals. The two fields some important points of contact. We would like share readership our vision role a (nano)materials scientist can play in fight against COVID-19 pandemic. As researchers specifically working on surfaces nanomaterials, this letter underline...

Abstract Organic bioelectronic sensors are gaining momentum as they can combine high‐performance sensing level with flexible large‐area processable materials. This opens to potentially highly powerful systems for point‐of‐care health monitoring and diagnostics at low cost. Prominent detect biochemical recognition events, electrolyte‐gated organic field‐effect transistors (EGOFETs) electrochemical (OECTs) easily fabricated operated. EGOFETs recently shown be capable of label‐free...

Immunoglobulin M (IgM) single-molecule and label-free detection is demonstrated, for the first time, by means of an electrolyte-gated thin-film transistor. The sensor integrates a millimeter-wide self-assembled monolayer (SAM) that includes trillions anti-IgM capturing proteins. This adds generality to already introduced single molecule with transistor (SiMoT) platform. Besides extremely high sensitivity, SAM confers SiMoT bioelectronic selectivity here assessed measuring differential...

Abstract Electric fields have been highlighted as a smart reagent in nature’s enzymatic machinery, they can directly trigger or accelerate chemical processes with stereo- and regio-specificity. In catalysis, controlled mass transport of species is also key facilitating the availability reactants active reaction site. However, recent progress developing clean catalysis that profits from oriented electric limited to theoretical experimental studies at single molecule level, where both control...

Abstract Early diagnosis of the infection caused by human immunodeficiency virus type-1 (HIV-1) is vital to achieve efficient therapeutic treatment and limit disease spreading when viremia at its highest level. To this end, a point-of-care HIV-1 detection carried out with label-free, low-cost, ultra-sensitive screening technologies would be great relevance. Herein, label-free single molecule p24 capsid protein large ( wide-field ) single-molecule transistor (SiMoT) sensor proposed. The...
