New method can produce designer hydrogels: Prof. Maji & team


 A team of scientists at the Bengaluru-based Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have developed a new technique that promises to produce hydrogels that could be used for a variety of applications like cleaning of industrial wastewater.

The method involves self-assembly of tiny cubes of metal-organic compounds into hydrogels with the help of molecular binders. The make-up of the resulting hydrogel depends on the size, shape and geometry of the molecular binder.

For instance, when researchers used cationic ammonia-based molecular binder, the resulting hydrogel had a nano-tubular shape with negative charge on its surface. It can be used as a gel-chromatography separator to separate cationic species from their anionic counterparts from any material.

This hydrogel can bind different types of metal ions including toxic heavy metal ions.The researchers have tried it out with waste water samples containing dyes. When they passed the samples through a column of the hydrogel, the dye with positive charged got attached to the surface and cleaner water flowed out.
