Electrochemical methods for on-site multidrug detection at festivals
Two electrochemical methodologies, i.e. flowchart and dual-sensor, were developed to aid law enforcement present at festivals to obtain a rapid indication of the presence of four illicit drugs in suspicious samples encountered.
Paper
From glow-sticks to sensors: single-electrode electrochemical detection for paper-based devices
A versatile biosensing platform based on a single electrode electrochemical system, paper-based devices and glow sticks.
Paper
An integrated platform for metamaterial-based sensing and surface acoustic wave-based acoustofluidics utilising circular interdigital transducers
A key challenge in developing lab-on-a-chip devices is integrating various functionalities such as liquid manipulation and sensing on a single platform, which conventionally requires different technologies to be separately optimized.
About this collection
In 2022, the very first issue of Sensors & Diagnostics was published. Since then, the journal has published high-quality work from world-class researchers. In celebration of this, we wanted to showcase some of the very best work published by the journal in this post-publication collection.
Featuring a global cohort of authors, with topics ranging from carbon-based electrochemical sensors to polymer-based humidity sensors, we are proud to present some of the best papers published in the journal through the ‘Sensors in a Digital World’ collection.
