Hot summers and physical activities can produce unpleasant sweaty smell. What if you can do away with the smell with a burst of pleasing aroma? Now, researchers have modified cotton fabric to release a lemony citronella smell upon contact with sweat.The research was published in the journal 'ACS Applied Materials & Interfaces.'In recent years, scientists have developed smart fabrics that react to stimuli such as light, temperature or mechcal stress and respond in certain ways, such as by changing colour or conducting an electrical signal.Researchers have explored different methods to release fragrances from fabrics. Carla Silva, Artur Cavaco-Paulo and colleagues wanted to develop and compare two new strategies for releasing a fragrance -- b-citronellol, a lemongrass-derived scent used in some insect repellants -- from cotton fabric in response to sweat.The first approach involved an odorant-binding protein (OBP) found in pigs' nose that binds to b-citronellol and other scent molecules. To the OBP, the researchers attached a protein domain, called a carbohydrate-binding module (CBM) that binds to cotton.In their second strategy, the researchers packaged the fragrance in liposomes that displayed CBMs, which anchored the lipid carriers and their cargo to the fabric.The team exposed a modified cotton fabrics to an acidic sweat solution, and the low pH of the simulated perspiration caused the OBP and liposomes to release b-citronellol.Comparing the two strategies revealed that the OBP released a quick burst of scent, while the liposomes showed a slower, controlled release.The liposomes could also hold more fragrance than the other approach. The two strategies could prove useful for different clothing applications, the researchers said.( With inputs from ANI )
