The utilization of black phosphorus and its monolayer (phosphorene) few-layers in field-effect transistors has attracted a lot attention to this elemental two-dimensional material. Various studies on optimization transistors, PN junctions, photodetectors, other applications have been demonstrated. Although chemical sensing based devices was theoretically predicted, there is still no experimental verification such an important study In article, we report nitrogen dioxide (NO2) using...
An ultrasensitive electrochemical biosensor based on a gold nanoparticles/graphene/polypyrrole composite modified electrode and signal amplification strategy employing methylene blue is developed as potential tool for the detection of miRNA-21.
We demonstrate a scalable and facile lithography-free method for fabricating highly uniform sensitive In2O3 nanoribbon biosensor arrays. Fabrication with shadow masks as the patterning instead of conventional lithography provides low-cost, time-efficient, high-throughput biosensors without photoresist contamination. Combined electronic enzyme-linked immunosorbent assay signal amplification, arrays are optimized early, quick, quantitative detection cardiac biomarkers in diagnosis acute...
Semiconducting SnO2 nanowires have been used to demonstrate high-quality field-effect transistors, optically transparent devices, photodetectors, and gas sensors. However, controllable assembly of rutile is necessary for scalable practical device applications. Here, we aligned, planar grown on A-plane, M-plane, R-plane sapphire substrates.

Nanostructure field-effect transistor (FET) biosensors have shown great promise for ultra sensitive biomolecular detection. Top-down assembly of these sensors increases scalability and device uniformity but faces fabrication challenges in achieving the small dimensions needed sensitivity. We report top-down fabricated indium oxide (In2O3) nanoribbon FET using highly scalable radio frequency (RF) sputtering to create uniform channel thicknesses ranging from 50 10 nm. combine this sensing...
Sometimes, smaller size is not always better, and looking for nanomaterials that offer better device performance requires consideration of their properties at the first stage. In this study, effects polyethylenimine-capped AuNPs (PEI-AuNPs) proteins on immunosensor performances, namely, sensitivity limit detection, are examined. The size-effect investigation PEI-AuNPs involves modification surface disposable screen-printed carbon electrodes to support primary antibodies ability load...
