From IIT: Clean­ing toxic water for rivers, faster ty­phoid di­ag­no­sis

TECH THAT HELPS Schol­ars de­velop ma­te­rial that ab­sorbs ef­flu­ents as they flow through pipes and de­vice that helps in early and cheaper de­tec­tion of ty­phoid

NEW DELHI: A group of schol­ars from the In­dian In­sti­tute of Tech­nol­ogy (IIT) Delhi have de­vel­oped a ma­te­rial that can eas­ily ab­sorb toxic el­e­ments and al­low only treated water to be dis­charged into rivers.

The in­no­va­tion, that makes use of cheap nano ma­te­rial read­ily avail­able in mar­kets, comes at a time when the gov­ern­ment has been com­ing up with new ways and meth­ods to clean the water bod­ies of Delhi, es­pe­cially the Ya­muna.

The tech­nol­ogy en­vi­sions the spe­cial ma­te­rial be­ing coated with starch and other chem­i­cals, and then used in­side the pipes of fac­to­ries that re­lease ef­flu­ents or be­ing placed as a gauge at the pipe’s open­ings to soak up the ef­flu­ents as they flow.

“Starch as you know is very cheap and a very small amount of it has been used to make this ma­te­rial. As per the ex­per­i­ment con­ducted, this ma­te­rial ab­sorbs 95 per­cent of toxic met­als and will help in sav­ing a lot of the aquatic life,” said Ara­binda Baruah, re­search scholar from depart­ment of chem­istry IIT-Delhi.

Ac­cord­ing to the re­search schol­ars, this would be a very use­ful in poly­mer, tex­tile and the leather fac­to­ries.

This project will be on dis­play on April 18 dur­ing the IIT-Open House — an an­nual event that show­cases in­no­va­tive projects.

The other project cre­ated by IIT-Delhi stu­dents is some­thing called the “im­muno mag­netic cell cap­ture” that is ex­pected to help the health­care sec­tor, mak­ing di­ag­no­sis of ty­phoid faster and cheaper.

At present, it takes 72 hours to de­ter­mine whether a per­son is suf­fer­ing from ty­phoid. The new de­vice, how­ever, will help de­tect pos­si­ble ty­phoid in just six hours.

“Bac­te­rial in­fec­tions like cholera and di­ar­rhoeal diseases are ma­jor cause of death due to lack of clean water and san­i­ta­tion. Ex­ist­ing meth­ods do not make pos­si­ble di­ag­no­sis easy. Our de­vice will de­tect in­fec­tion early and re­duce cost,” said Ravikr­ish­nan Elan­go­van, as­sis­tant pro­fes­sor from the depart­ment of bio-chem­i­cal en­gi­neer­ing and biotech­nol­ogy.

De­vel­oped with the help of two other pro­fes­sors from dif­fer­ent depart­ment and some PhD schol­ars, the por­ta­ble im­muno mag­netic cell cap­ture de­vice will de­tect in­fec­tion by test­ing stool and blood.

“Di­ag­no­sis now cost `500. Af­ter our de­vice is used, it will not cost more than `200. The de­vice will work on both bat­tery and elec­tric­ity,” said Vivekanan­dan Peru­mal, as­sis­tant pro­fes­sor of school of bi­o­log­i­cal sci­ences.

This de­vice has al­ready been patented and the ones who have in­no­vated have plans to be take it to a com­mer­cial level.

The Open House will also show­case a project by Viren­dra Ku­mar Sharma, who makes bells, pens, per­fume bot­tles from glass blow­ing.

“Nor­mally lab­o­ra­tory in­stru­ments are made from glass blow­ing due to high cost of the glasses. The other things I have learnt over the years,” said Sharma, who has been work­ing at IIT-D for over 30 years now.

Schol­ars of IIT- Delhi, have come up with de­vices, like a spe­cial ma­te­rial that ab­sorbs toxic el­e­ments from water (top), and a por­ta­ble de­vice that helps in early de­tec­tion of diseases like ty­phoid (above). These will be on dis­play on April 18 dur­ing...
