We developed retroreflective Janus microparticles (RJPs) as a novel optical immunosensing probe for use in nonspectroscopic retroreflection-based immunoassay. By coating the metals on hemispherical surface of silica particles, highly reflective RJPs were fabricated. On basis retroreflection principle, responded to polychromatic white light sources, contrast conventional probes, which require specific monochromatic light. The signals from distinctively recognized shining dots, can be...
Flexible and highly ordered nanopillar arrayed electrodes have brought great interest for many electrochemical applications, especially to the biosensors, because of its unique mechanical topological properties. Herein, we report an advanced method fabricate produced by soft-/photo-lithography metal evaporation. The array exhibited superior properties in regard with wide space response electrolytes, enabling sensitive analysis. As-prepared gold silver on arrays exhibit stable performance...
Atopic dermatitis (AD), a prevalent skin condition often complicated by microbial infection, poses significant challenge in identifying the responsible pathogen for its effective management. However, reliable, safe tool pinpointing source of these infections remains elusive. In this study, novel on-site detection that combines chemically functionalized nanotopology with genetic analysis is proposed to capture and analyze pathogens closely associated severe atopic dermatitis. The features 3D...
Abstract In molecular diagnostics, the digital polymerase chain reaction (dPCR) has been considered a promising point-of-care testing (POCT) method for rapid and accurate analysis of respiratory infections. To improve its practical applicability, it is necessary to develop mass-producible reproducible dPCR system nucleic acid partitioning; additionally, must provide customized portable analysis. this study, we report an advanced mass-production fabrication microwell array-based chips...
Abstract The sense of spiciness is related to the stimulation vanilloid compounds contained in foods. Although, commonly considered as part taste, it more classified pain stimulated on a tongue, namely, pungency, which described tingling or burning tongue. Herein, first, reusable electronic tongue based transient receptor potential 1 (TRPV1) nanodisc conjugated graphene field‐effect transistor fabricated and spiciness‐related evaluation with electrode demonstrated. pungent compound reactive...
Abstract The noninvasive early detection of biomarkers for Alzheimer’s disease (AD) is essential the development specific treatment strategies. This paper proposes an advanced method fabricating highly ordered and flexible nanopillar-based electrochemical biosensors by combination soft/photolithography metal evaporation. nanopillar array (NPA) exhibits high surface area containing 1500 nm height 500 diameter with 3:1 ratio. In regard physical properties polyurethane (PU) substrate, developed...
Gold is of considerable interest for electrochemical active surfaces because thiol-modified chemicals and biomolecules can be easily immobilized with a simple procedure. However, most gold are damaged repetitive measurements, so they difficult to reuse. Here we demonstrate novel cleaning method reuse electrodes protocol that easy nontoxic. This consists two steps by using different solutions. The 1st step cyclic voltammetry sweep very low concentration sulfuric acid, the 2nd potassium...
Abstract Organic interfacial compounds (OICs) are required as linkers for the highly stable and efficient immobilization of bioprobes in nanobiosensors using 2D nanomaterials such graphene. Herein, we first demonstrated fabrication a field‐effect transistor (FET) via microelectromechanical system process after covalent functionalization on large‐scale graphene by introducing oligo(phenylene‐ethynylene)amine (OPE). OPE was compared to various OICs density functional theory simulations...
Sensitive and accurate capture, enrichment, identification of drug-resistant bacteria on human skin are important for early-stage diagnosis treatment patients. Herein, we constructed a three-dimensional hierarchically structured polyaniline nanoweb (3D HPN) to enrich, detect on-site by rubbing infected skins. These unique hierarchical nanostructures enhance capture efficiency help severely deform the surface entrapped them. Therefore, 3D HPN significantly contributes effective reliable...
