想越出汗闻起来越好吗?科学家们找到了一个很有希望的解决方案

We've all experienced being in a gaggle of people and smelling the stench of sweat.

我们都经历过置身于嘈杂的人群中，闻到汗水的恶臭。

Then you panic, hoping the dreadful odor isn't coming from you.

然后你惊慌失措，希望那可怕的气味不是来自你。

Luckily, some scientists are trying to solve this pervasive problem.

幸运的是，一些科学家正试图解决这个普遍存在的问题。

A team of engineers from the University of Minho in Portugal have discovered a way to change cotton fabric so that it emits a citronella smell when it comes in contact with sweat. Their work is published in ASC Applied Materials & Interfaces.

来自葡萄牙米尼奥大学的一组工程师发现了一种改变棉织物的方法，当棉织物与汗水接触时会散发出香茅的气味。他们的研究成果发表在ASC应用材料与界面杂志上。

The team used a protein found in pigs' noses that binds to scent molecules and added carbohydrate-binding molecules that latch on to cotton.

研究小组使用了猪鼻子中发现的一种蛋白质，这种蛋白质与气味分子结合，并添加了碳水化合物结合分子，这种分子可以吸附在棉花上。

They also found a second way to achieve the same result using fat-like liposomes to bind the scent to the fabric.

他们还发现了另一种方法来达到同样的效果，那就是使用类似脂肪的脂质体来将气味结合到织物上。

The difference between the two methods is that the first emits the citronella scent in a quick burst while the liposomes release the scent in a slower, more controlled manner.

两种方法的不同之处在于，第一种方法在短时间内释放香茅气味，而脂质体则以更慢、更可控的方式释放香茅气味。

And while citronella might not smell like high-end cologne or perfume, it does have the added benefit of being an insect repellent.

香茅可能闻起来不像高档古龙水或香水，但它确实有驱虫的额外好处。

The concept was built on existing smart fabrics that change color or conduct an electric signal in response to stimuli like light or temperature.

这个概念是建立在现有的智能织物上的，这些织物可以根据光或温度等刺激改变颜色或传导电信号。

The new fabric will need to be tested on a larger scale, but it's a promising use of fragrance and technology as a way to mask one of the world's more unflattering whiffs.

这种新面料还需要更大规模的测试，但它很有希望利用香味和技术来掩盖这种世界上最不讨人喜欢的气味之一。
