Abstract:
The introduction of innovative sensing approaches is of increasing interest in the development of analytical platforms and methodologies for the colorimetric, fluorimetric, and/or optical detection of important analytes. Herein, the synthesis of a novel squaraine derivative is reported, as well as its successful utilization in the colorimetric and fluorimetric determination of thiols. The reported squaraine was also evaluated as a pH sensor. In addition, a promising paper-based colorimetric method for mercury detection was developed and evaluated.

Potentiometry: Types of Electrodes
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...
