Bacterial Vesicles Coated on Gold Nanoparticles to Combat TB

29 Dec 2022 under Focus

Researchers from IISc have designed a new method to deliver a vaccine candidate for tuberculosis (TB). It involves using spherical vesicles secreted by bacteria coated on gold nanoparticles which can then be delivered to immune cells. This can potentially trigger an immune response and offer protection against the disease.   Caused by the bacterium Mycobacterium tuberculosis, […]

Tracking Cancer Without Culture

3D replicas of tissues in the lab are enabling scientists to get better insight into cell organisation and behaviour In September 2022, the US Senate unanimously passed the FDA modernisation Act 2.0 bill, which suggests reforms to the archaic Food, Drug, and Cosmetic Act that mandated testing drugs and cosmetics on animals for toxicity studies. […]

Using Nanosheets to Identify Bacterial Strain and Drug Resistance

11 Oct 2022 under Highlights

Researchers from the Department of Organic Chemistry and Department of Molecular Reproduction, Development and Genetics in IISc have developed an optical nanosheet sensor to identify disease-causing microbes from urine samples. Optical sensors are faster and simpler than culture-based methods and PCR. Nanosheet sensors such as those made of Graphene Oxide (GO) have a high surface […]
