IIT Hyderabad team uses plant extract, heat to kill cancer cells

IIT Hyderabad used chlorophyll-rich extract of a medicinal plant encapsulated in nanoparticles along with a dye to kill cancer cells when exposed to near-infrared light. The cancer cells were killed through reactive oxygen species-mediated autophagy. The extract was selective in killing only cancer cells. Lipid-based nanoparticles encapsulating chlorophyll-rich extract of a medicinal plant Anthocephalus cadamba and … Continue reading IIT Hyderabad team uses plant extract, heat to kill cancer cells

IIT Jodhpur fabricates a highly sensitive hydrogen sensor

A research team from IIT Jodhpur and IIT Hyderabad have together fabricated a sensor that can detect hydrogen gas even when present at extremely low concentration of 1 ppm. The sensitivity is 30% at 1 ppm hydrogen concentration and 74% at 100 ppm concentration. A sensor that can detect hydrogen gas even when present at … Continue reading IIT Jodhpur fabricates a highly sensitive hydrogen sensor

IIT Hyderabad develops waterproofing material using fly ash

Researchers at IIT Hyderabad have developed a cheap waterproofing material by coating fly ash, a waste by-product from coal-based thermal power plants, with stearic acid. The surface can be made to behave like one of the two naturally occurring water-repelling materials — rose petals or lotus leaves — by varying the surface roughness. Researchers at … Continue reading IIT Hyderabad develops waterproofing material using fly ash

Toxic mercury in fish increases with ocean warming, overfishing

Based on data and modelling, researchers from Harvard University have found that the amount of toxic mercury (methylmercury) in fish higher in the food chain can change due to two reasons — ocean warming and dietary shifts due to overfishing by humans. Despite a decrease in seawater concentration of methylmercury since the late 1990s, the … Continue reading Toxic mercury in fish increases with ocean warming, overfishing

IIT Hyderabad: A step closer to oral administration of Kala-azar drug

Using a novel drug-delivery approach, IIT Hyderabad researchers have made oral administration of the drug Amphotericin B for treating Kala-azar and fungal infection possible. The drug encapsulated in polymer nanofibres and made into tablets was released in a controlled and sustained manner for 10 days. By encapsulating an antifungal drug in polymer nanofibres, researchers at … Continue reading IIT Hyderabad: A step closer to oral administration of Kala-azar drug

IIT Hyderabad fabricates device for early diagnosis of heart attack

IIT Hyderabad researchers have fabricated a a microfluidic device that can detect cardiac biomarker cardiac troponin I over a wide range. The microfluidic device can detect the biomarker even when its concentration is as low as 0.005 nanogram per ml. A cardiac biomarker — cardiac troponin I — that is widely used for early diagnosis … Continue reading IIT Hyderabad fabricates device for early diagnosis of heart attack

IIT Hyderabad’s device detects heart attack early

IIT Hyderabad researchers have fabricated a low-cost, ultra-sensitive device that is capable of detecting the cardiac biomarker troponin T protein. Compared with the current limit of detection, the bioelectrode was able to detect troponin T even when it is 10,000 times less in concentration. A low-cost, ultra-sensitive device that is capable of detecting the cardiac biomarker … Continue reading IIT Hyderabad’s device detects heart attack early

IIT Hyderabad’s novel composite keeps tomatoes fresh for 30 days

IIT Hyderabad researchers have developed a novel composite using bacterial cellulose impregnated with silver nanoparticles. The food packaging material has antimicrobial activity and allows appropriate exchange of gases and moisture. Tomatoes wrapped using the composite remained fresh without any microbial spoilage even at the end of 30 days. Researchers at Indian Institute of Technology (IIT) … Continue reading IIT Hyderabad’s novel composite keeps tomatoes fresh for 30 days

IIT Hyderabad team fabricates e-skin for motion monitoring

Researchers from IIT Hyderabad have fabricated an electronic skin (e-skin) using carbon nanotubes deposited on a layer of PVC-free pencil eraser. The e-skin is sensitive and can simultaneously sense pressure and strain. The device can be used for human motion monitoring in the case of elderly and infants, and may ultimately find applications in flexible … Continue reading IIT Hyderabad team fabricates e-skin for motion monitoring

IIT Hyderabad team recycles polystyrene using orange peel extract

Polystyrene gets dissolved almost instantly in a solution of orange peel extract that is obtained by squeezing the orange peels. The polystyrene dissolved in the extract is drawn into fibres using wet/solution spinning and the fibre is made into a non-woven fabric which can be used for removing oil. The innovation by researchers from IIT Hyderabad won a gold … Continue reading IIT Hyderabad team recycles polystyrene using orange peel extract
