Correct Answer : Option (B) - IIT Madras
Researchers from IIT Madras and IISER Kolkata have developed a method to detect minute quantities of chemicals in solution.
* They use a variation of absorption spectroscopy that surpasses the systemic limits imposed by conventional absorption spectroscopy.
* With this technique, they can, in principle, illuminate the insides of cells and detect minuscule quantities of substances present there. The work was published in Nanoscale.
