Delhi team fabricates a sensor to detect drug-resistant leukaemia

A highly sensitive carbon nanotube-based sensor capable of detecting multidrug-resistant myeloid leukemia cells even when present at very low concentration of 10 cells per ml has been fabricated by Delhi-based researchers. Using chemical vapour deposition technique, the team led by Prof. S.S. Islam from the Centre for Nanoscience and Nanotechnology at the Jamia Millia Islamia … Continue reading Delhi team fabricates a sensor to detect drug-resistant leukaemia

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: 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

TIFR desalinates seawater without using electricity

TIFR researchers have produced gold nanoparticles that can absorb sunlight over the entire visible region and even the near infrared light. They used such gold nanoparticles to absorb energy from sunlight to be able to desalinate seawater to produce drinking water. The gold nanoparticles can also be used for converting carbon dioxide to methane more … Continue reading TIFR desalinates seawater without using electricity

IISc team submits more evidence of superconductivity

In a new preprint posted in arXiv on June 5, the IISc team has provided evidence of signatures of critical current — the current at which the superconductor is no longer stable and becomes resistive. The critical current data is a strong indicator of superconductivity. Further evidence of possible superconductivity in gold-silver nanostructures has been … Continue reading IISc team submits more evidence of superconductivity

Amity University achieves faster healing of diabetic wound

Hydrogel nanotubes containing ice in a helical structure developed by Amity University researchers has been found to quicken diabetic wound healing. Complete healing of wounds in Wistar rats was seen on day 16. No scarring was seen and fur growth at the wound site was observed. Hydrogel nanotubes containing ice in a helical structure developed … Continue reading Amity University achieves faster healing of diabetic wound

Silver atoms of nanoparticles are mobile, IIT Madras team finds

IIT Madras researchers have discovered that atoms of nanoparticles made of two silver isotopes having just 25 atoms each rapidly exchanged their positions when the isotopes are mixed in solution. New particles composed of nearly 50% mixture of both isotopes were formed. This is akin to the exchange of hydrogen and deuterium atoms when normal … Continue reading Silver atoms of nanoparticles are mobile, IIT Madras team finds

JNCASR team fully restores long-term memory in mice with Alzheimer’s 

JNCASR researchers along with French counterparts have been able to fully restore neuron to neuron connections and long-term memory in mice with Alzheimer’s disease using a small molecule that activates two enzymes. The molecule attached to carbon nanospheres was able to breach the blood-brain barrier and reach the brain in sufficient concentration. Using a small … Continue reading JNCASR team fully restores long-term memory in mice with Alzheimer’s 

Podcast – Sniffing out lung cancer

IIT Bombay researchers explain how the platform that they developed will help sniff out volatile organic compounds in a gas phase at single molecular levels. Since certain organic compounds in exhaled breath are clinically established biomarkers for early stage lung cancer, the platform can potentially be used for detecting early stage lung cancer. Validation on patients … Continue reading Podcast – Sniffing out lung cancer

IIT Bombay’s platform sniffs out lung cancer, explosives

IIT Bombay researchers have developed a platform that will help sniff out volatile organic compounds in a gas phase at single molecular levels. Detecting certain organic compounds in exhaled breath will help diagnose early stage lung cancer. Validation on patients is yet to be done. The same platform can also be used to monitor air-pollution levels … Continue reading IIT Bombay’s platform sniffs out lung cancer, explosives
