KL University develops paper sensor to measure Vitamin-D deficiency; the test eliminates laboratory testing and costs just a fraction of the existing tests.
KL University has developed an extremely cost-effective test for Vitamin deficiency. What makes the test more interesting is its being a paper sensor based text instead of existing laboratory based tests, which also cost more. The cost of this paper sensor will come to approximately Rs 40 to 50, whereas the cost of commercially available tests for Vitamin-D in hospitals and labs is around Rs 1,500 to Rs 2,000.
The KL Deemed-to-be University has developed this unique handmade paper sensor that can measure Vitamin-D deficiency with high accuracy. It is developed by the team of Pradeep Kumar Brahman from the Department of Chemistry along with Tummala Anusha, a research scholar on the institute’s Andhra Pradesh campus.
This technology brings in new hope as smaller clinics, dispensaries in remote areas, medical facilities in geographically inaccessible locations, and smaller facilities can now be able measure Vitamin-D deficiencies without any bulky equipment or labs. The work was recently published in the microchemical journal, Elsevier.
The KL University is based in Andhra Pradesh’s Guntur district.
The sensor is developed by designing a paper electrode and printing it on an A4 paper with a specially designed ink that includes cobalt silver doped copolymer ionic liquid and acts as a sensor to detect vitamin D deficiency.
The KLU team says that the accuracy of the sensor is over 94%, which is at par with the existing, commercially available tests. The sensor produces results and generates reports within 30 minutes, saving crucial time for diagnoses.
Indians usually do not get tested for Vitamin D deficiency as it does not produce visible symptoms. Dr Brahman said, “This is possibly the first-of-its-kind and the most affordable Vitamin D deficiency sensor in national and international markets. It will make Vitamin D deficiency testing affordable for cost-conscious countries such as India. We took two years to finish the research and come up with this pioneering product. This handmade sensor is accurate and reliable for the monitoring of vitamin D deficiency in remote areas where limited resources are available.”
