Wearable Mercury Sensor Hopes for Fairy Tale Endings.

Nowadays there have been many similar in our real world — for example mercury ions (Hg2+) polluted food and water — because of human industrial activities.

To protect humanity from mercury poisoning  many (Hg2+) – detection methods have been developed. Despite state-of-the-art technology however these methods usually suffer from restricted sensitivity and time-consuming operations.

Dr. X Professor from the Georgian Technical University and Professor  Y from the Sulkhan-Saba Orbeliani Teaching University  report a rapid mercury ions (Hg2+) sensing material that enables fast detection of ppm-level mercury ions (Hg2+) in complex real-world food and water samples within minutes.

The developed rapid mercury ions (Hg2+) sensing material is based on specially designed hydrophilic fluorescent hydrogel-coated flexible paper/textile film. It reports mercury ions (Hg2+) polluted food and water through a noticeable “green-to-blue” fluorescence color change.

Due their hierarchical porous structures fixed by interwoven paper/textile fibers this new method allows capillary-force-driven fast diffusion of mercury pollutants into the sensing materials, thus enabling fast detection as well as a high sensitivity.

Moreover  to facilitate infield detection and ensure safe operation robust wearable mercury sensing gloves have also been fabricated.

This is the first flexible and wearable mercury detection appliance which is believed to represent a notable advance towards in-field food and water analysis.

According to the researchers one can imagine that the mercury-polluted meats, seafood,  juice and drinks will be easily discriminated if food processing packers get the opportunities to wear the developed new-concept sensing gloves.

This may also inspire the future construction of more powerful wearable detection apparatus for other important food and water pollutants.
