Ensuring food security is crucial for public health, and the presence of mycotoxins, produced by fungi in improperly stored processed or unprocessed food, poses a significant threat. This research introduces novel approach - disposable aptasensing platform designed detection ochratoxin A (OTA). The employs gold-nanostructured screen-printed carbon electrodes functionalized with ferrocene derivative, serving as an integrated faradaic transducing system, anti-OTA aptamer bioreceptor site....
In this work, we report on the design of an enzyme-less sensitive and selective electrochemical electrode for ascorbic acid (AA) detection using a modified screen-printed melanin-like nanoparticles (Mel-NPs). Cyclic voltammetry shows that melanin-modified exhibits high electrocatalytic activity acid. The serve as shuttle to transport electrons from surface. is endowed with large dynamic window ranging 5 500 ppb. quantification limits were estimated be 0.07 0.23 ppb, respectively. was...
The demand for on-site nanodevices is constantly increasing. technology development the design of such devices highly regarded. In this work, we report a disposable platform that structured with cauliflower-shaped gold nanoparticles (cfAuNPs) and show its applications in immunosensing enzyme-based detection. electrochemical reduction Au(III) allows electrodeposition dispersed on surface screen-printed carbon electrodes (SPCEs). nanostructures were functionalized using ferrocenylmethyl lipoic...
ApoE Alzheimer's disease biomarker can be sensitively detected by a label-free platform using flexible ferrocene-terminated alkyl chains. The immunorecognition triggers conformational changes, which improve the rate constants of electron-transfer.
