项新的研究表明,当种出来的棉花所具有的分子被赋予吸引人的属性(如荧光或磁性)时,也许在某一天人们无需再对织物进行化学处理就能获得同样的品质效果。将合成的多聚物用于织物可导致一系列吸引人的属性,但添加到植物中的任何东西都可能会被洗脱或被磨损掉。“此外,虽然织物中所用的许多纤维是合成的(如聚酯纤维),但有些消费者更喜欢天然纤维以避免如感觉异常、皮肤刺激、平滑性及重量等相关问题。”在这里,Filipe Natalio和同事制造出的棉花纤维中含有荧光和磁性属性的复合材料。他们合成了葡萄糖衍生物,后者能将期望的分子递送给棉花(陆地棉)的生长中的胚珠。这些分子本身就这样被埋置于棉花纤维之中,而非以化学处理形式被加入。据作者报告,所得到的纤维可分别显示出荧光或磁性,但它们要比没有埋置这些复合材料的原始棉纤维脆弱一些。他们提出,类似的技术也可被扩展到其它的生物系统中,如细菌、竹子、丝绸和亚麻中,这不啻为开辟了一个“材料种植”的新时代。
