In 2020, the new European Drinking Water Directive will be updated to include new drinking-
water safety parameters. These will introduce reduced thresholds for the presence of heavy …

Electrochemical biosensors combine the sensitivity of electroanalytical methods with the
inherent bioselectivity of the biological component. The biological component in the sensor …

Screen-printed electrodes (SPEs), which are used as economical electrochemical
substrates, have gone through significant improvements over the past few decades with …

Heavy metals such as lead, mercury, cadmium, zinc and copper are among the most
important pollutants because of their non-biodegradability and toxicity above certain …

The development of analytical methods that respond to the growing need to perform rapid 'in
situ'analyses shows disposable screen-printed electrodes (SPEs) as an alternative to the …

The pursuit of biocompatible, breathable and skin-conformable wearable sensors has
predominantly focused on synthetic stretchable hydrophobic polymers. Microbial …

In poor and remote zones of the world, such as the Amazon region, the lack of analytical
infrastructures prevents regular quality assessments of water systems. The access to …

A bismuth-modified carbon nanotube electrode (Bi-CNT electrode) was employed for the
determination of trace lead, cadmium and zinc. Bismuth film was prepared by in situ plating …

This paper presents a fast and sensitive approach for simultaneous electrochemical
determination of lead and copper based on a commercial screen-printed gold electrode …

Mercury is a metal that has been extensively studied, in large part due to its high toxicity.
Therefore, mercury levels must be monitored in different sample types using analytical …
