Chemical analysis based on colour changes recorded with imaging devices is gaining
increasing interest. This is due to its several significant advantages, such as simplicity of …

Published data on the use of household color-recording devices, such as office scanners,
digital cameras, web cameras, mobile phones, and smartphones, in quantitative chemical …

The growing concern for sustainability and environmental preservation has increased the
demand for reliable, fast response, and low-cost devices to monitor the existence of heavy …

The present paper describes the use of a microfluidic system to synthesize carbon dots
(Cdots) and their use as optical pH sensors. The synthesis is based on the thermal …

Zincon (ZI) is one of the most common chromophoric chelating probes for the determination
of Zn 2+ and Cu 2+ ions. It is also known to bind other metal ions. However, literature data …

In this study a device for automatic electrochemical analysis was designed. A three
electrodes detection system was attached to a positioning device, which enabled us to move …

A portable sensor has been developed for in situ measurements of pH within aqueous
environments. The sensor design incorporates microfluidic technology, allowing for the use …

One of the main limiting factors in optical sensing arrays is the reproducibility in the
preparation, typically by spin coating and drop casting techniques, which produce …

Two types of cross-linked polymeric dye films that exhibit reversible color changes in
response to pH were prepared. Upon protonation, films with a nitrophenol dye moiety (NP) …
