在20世纪初前后，医学界经历了一场形象革新。医生们将传统的黑大褂换成了白大褂，与实验室里的科学家们所穿的相仿。在那个许多行医者仍是江湖医生、冒牌医生和骗子的年代，这一改变旨在提升医师的科学可信度。随着消毒剂的重要性日益广为人知，白色也被认为具有能够显脏的优点。2如今，许多医生可能会穿着日常便服或者蓝或绿色的“刷手服”，据说这些有助于减轻在灯光明亮的手术室中产生的眼部疲劳。白大褂被认为与其他颜色衣服一样能够轻易地传播疾病，尤其是当长袖拂过多种物体表面时。许多诊所与医院现已对全体工作人员实行“肘部以下裸露”的政策，无论是穿着制服时还是私服时。此政策的目的在于鼓励医护人员更彻底地洗手。然而，倘若医护人员所穿的衣物能主动帮助阻止病菌传播呢？某些金属，如金和银，具有天然抗菌特性，被用于涂覆某些固体物品，如医疗植入物。但是，在具有弹性、可折叠的织物上添加金属涂层颇为棘手，且那些涂层在洗衣机中很快就会被冲刷殆尽。曼彻斯特大学的刘旭庆博士认为，所需之法是为织物制造一种能真正地紧密附着在织物上的抗菌涂层。3刘博士选择的金属是铜，而非金或银。铜表现出同样的杀菌特性，但却有着比那两种贵金属便宜得多这一优势，从而使得商业化涂层工艺更容易设计。4刘博士与来自中国的两所机构——兰州的西北民族大学与重庆的西南大学——的同事合作，一直以来，采用一道化学工艺处理织物样品——将一种被称为为“聚合物刷”的结构接枝到织物表面。顾名思义，在电子显微镜下以几纳米（即十亿分之一米）的分辨率观察时，这些丝状聚合物链看起来就像微小的、突起的鬃毛。接枝完成后，他们采用第二道化学工艺，在鬃毛上涂覆催化剂。随后，将织物浸入含铜溶液中，催化剂促使金属从中析出，并形成锚定在聚合物刷上的微小颗粒。它们结合得如此牢固，刘博士将所得涂层比作钢筋混凝土。然而，该过程发生在织物表面如此微小的尺度上，因此并不会影响成品材料的手感或质地。5刘博士与同事已能够将该工艺应用于棉和聚酯纤维。对棉花样本的抗菌性能测试表明，这种新材料在杀灭两种可能引发严重感染的病菌——大肠杆菌和金黄色葡萄球菌——方面，效果与银相当，甚至可能更胜一筹。样本的抗菌效果同样持久，经受住了超过30次的洗涤。6在一个人们日益关注医院获得性感染与抗菌耐药性的时代，将抗菌性能直接嵌入医疗服装中可能带来显著的公共卫生方面的益处。此类材料不仅可能减少临床环境中有害细菌的传播，还可能减少强效消毒剂的使用以及降低工业洗涤的频率——从而降低成本并减轻环境影响。除医院之外，在食品加工等卫生至关重要的行业，以及在运动服装或旅行装备等能够从持久清新中受益的消费品中，研究人员也看到了该技术的应用潜力。7该方法所涉及的化学工艺相当简单，这意味着该方法应该还比较容易扩大使用规模。研究人员已经在与公司洽谈这样做的可能性。目前仍将持续改进这一工艺，并对其他材料的表面进行处理。8刘博士也在从单根纤维层面开始展望其发明的全新前景。通过将含铜斑点的纤维纺成导电纱线，服装或可成为电路的织机，而不仅仅是布料。每根纤维都将充当细如发丝的导线，准备好将心电图导联网络缝入心内科医生的白大褂，或将温度传感器编织进护士的制服。由于金属颗粒被锁定在聚合物支架内，沿着每根纤维的长度分布，纱线能够保持柔韧，甚至可焊接到常规元件上而不断裂。电力可以来自缝入袖口的微型超级电容器，或来自沿病房每走一步都能收集能量的压电贴片。9该技术不必局限于白大褂：将电致变色染料接枝到相邻纤维上，同样的导体便可驱动图案随生物信号绽放和消退——压力燃起猩红，平静映现海蓝，血流将自己绘制成变幻的地形，呈现在外科医生的袖管上。有朝一日，手术室可能披覆智能纺织品，其交织的纤维随诊断数据脉动，将普通的医院工作服从被动的装束转变为主动的护理伙伴——半是服装，半是装置，并比以往更加斑斓多彩。Readthepassageandmatcheachpartwithitscorrespondingheading.Paras.1-2Paras.3-5Paras.6-7Paras.8-91.Thevisionofsmartwearablescraftedfrominnovativefibers2.Theinnovationofcopper-basedantibacterialcoatingforfabrics3.Public-healthbenefitsandpotentialapplicationsoftheinnovation4.ThechallengeofinfectioncontrolinmedicalattireReadingandsynthesizingScan
