Visceral leishmaniasis, or kala-azar, is an insidious disease that affects thousands of people every year. This illness can be fatal, if not diagnosed and treated on time. However, despite best efforts, India still lags behind in eliminating this disease completely. A recent study published in the journal PLOS Neglected Tropical Diseases has investigated the factors that lead to the delayed diagnosis and treatment of kala-azar.
By precisely tuning the metamaterial structures, researchers create a near-perfect light trap synchronised with molecular vibrations, paving the way for advanced sensors and optical devices.
