Wearable biosensors for the detection of analytes in sweat are an emerging and promising technology with important applications in monitoring a person’s physiological state. Sweat, being an easily accessible biofluid, shows great potential as a...

A critical characteristic for continuous monitoring using DNA biosensors is the design of the microfluidics system used for sample manipulation, effective and rapid reaction and an ultra-low detection limit of the analyte. The selection of the approp...

Ochratoxins are a group of mycotoxins produced as secondary metabolites by several fungi of Aspergillus and Penicillium species. Ochratoxin A (OTA) is the most toxic member of the group and can be found in a large variety of widely consumed foods, su...

Preliminary results on an electrosynthesized ion-imprinted polymeric (IIP) film for the development of a Co2+ sensor are reported herein. The sensor was prepared by CV electropolymerization of 2-aminophenol (2-AP) monomer in the presence of Co2+ ions...

Illicit drug consumption remains a problem to public safety and health, with abuse of illicit drugs having increased significantly over the last years. A concern related to this abuse is driving under the influence of drugs (DUID). Currently, police...

Amongst label-free optical sensors, those relying on silicon photonics are especially promising for the development of small-sized devices appropriate for applications at the point-of-need. In this context, our work over the last 10 years has focused...

Research on cellulose and its derivatives as biosensors is developing rapidly through the innovation and improvement of materials, chemical synthesis, and methods of preparation and formulation. This study presents the state of the art by introducing...

A simple to realize optical fiber sensor specific for uranium(VI) detection in water is reported to demonstrate the sensing approach’s capability to determine uranyl (UO22+) in water solution in the ppb range. The proposed sensor was obtained b...

Continuous monitoring is of upmost importance to manage emergency situations in healthcare. Therefore, we investigated the use of MAX30102, a commercial photometric biosensing module coupled to a ESP32 system-on-a-chip and its internet-of-things capa...

Since the outbreak of the COVID-19 pandemic, great emphasis has been placed on the development of rapid virus detection devices, the principle of operation of many of which is the detection of the virus structural protein spike. Although several such...
