In this study, a boron-doped diamond (BDD) electrode modified with cobalt oxide nanoparticles (CoONPs) is proposed as a working electrode for hydrocortisone (HC) detection in 0.1 M NaOH. CoONPs were synthesized via a g...

An electrochemical sensor for the determination of ciprofloxacin (CPR) was developed using a glassy carbon electrode modified with MIL-101/reduced graphene oxide (MIL-101/rGO). MIL-101/rGO was synthesized via a facile ul...

Facilitating efficient electrical communication between glucose oxidase (GOx) and electrode surfaces is important for the development of low-potential reagent-free glucose biosensors, yet unequivocal direct electron tran...

We developed a method to graft a tripeptide (glutathione) onto 5-hydroxy-1,4-naphthoquinone, an electropolymerizable molecule. The resulting thin conducting polymer presents a well-defined and stable electroactivity ...

Abstract A novel electrochemical sensor based on multi-walled carbon nanotubes doped with vanadium pentoxide/telluride (MWCNTs@V2O5/Te) was developed for the detection and quantification of morphine sulfate in real biolo...

Abstract Niclosamide (NA) is widely used as an insecticide in agriculture and fisheries; however, its excessive application poses potential risks to food security and aquatic ecosystems. In this study, halloysite nanotub...

Calibration of low-cost air quality sensors (LCSs) for total volatile organic compound (TVOC) and benzene, toluene, ethylbenzene, and xylenes (BTEX) quantification remains challenging due to the sensors' cross-sensitivit...

A real-time electrochemical sensing strategy for nicotine monitoring in smoke streams was developed using additively manufactured three-dimensional (3D) based on conductive polymer composites. Disc-type microelectrodes (...

TiO2 nanotubes were used to prepare gas sensor and the gas sensing properties towards toluene were analyzed. Titania nanotube arrays were fabricated via electrochemical anodization method in glycerol electrolytes contain...

ABSTRACT Background and Aims Influenza remains a globally prevalent respiratory infection that is challenging to diagnose accurately. This systematic review focuses on aptamer‐based tools for influenza virus detection,...

Abstract Per- and polyfluoroalkyl carboxylic acids (PFCAs) are of global concern for their ubiquitous presence in the environment. However, precise quantification of PFCAs remains challenging due to the shortage of stand...

Concepts adapted from radio frequency devices have brought forth subwavelength scale optical nanoantenna, enabling light localization below the diffraction limit. Beyond enhanced light–matter interactions, plasmonic na...

Abstract Wireless bioelectronics demand transduction strategies that are simultaneously sensitive, noise-resilient, and biologically safe. Conventional wireless sensors typically rely on dielectric capacitors with inhere...

Molecular imprinted polymers are custom made materials with specific recognition sites for a target molecule. Their specificity and the variety of materials and physical shapes in which they can be fabricated make them i...

El objetivo general de la presente tesis fue el diseño y la construcción de un biosensor amperométrico para determinar glucosa en jugos de fruta (utilizando el de manzana como modelo) que sea económico, de fácil con...
