“…,⼜称芯⽚实验室(Lab-on-a Chip)或者⽣物芯⽚。微流控技术 [2] 由微 机电加⼯系统(Micro-Electro-Mechanical System,MEMS)发展⽽来,它是⼀种在微⽶级微管 [3] 中精确操纵 [4] 微量流体的技术⼿段,具有将⽣物、化学等实验室微缩到⼀个⼏平⽅厘⽶芯⽚中的基本功能(样品的制备、 分离、反应、检测等)。随着材料科学的发展,作为微流控芯⽚载体的材料也层出不穷,从硅、玻璃到纸基 [5] 、 ⽔凝胶 [6] 以及各类聚合物和纳⽶材料 [7,8] 。与此同时,微流控芯⽚的制备技术也蓬勃发展如丝⽹印刷,喷墨打 印、3D 打印 [9][10] 等,⼀些⾼精尖的加⼯技术如⻜秒激光加⼯技术、双光⼦ 3D 打印技术也为⾼精密度的微流 控芯⽚的制作提供了更多可能性。 微流控芯⽚有着微型化、⾼灵敏度、⾼集成、⾼通量、反应快、检测时间短等技术优势,在⽣物医学研 究,合成分析 [11] ,司法鉴定等众多领域有着⼴泛的应⽤(可穿戴微流控设备 [12] 、体外医疗诊断 [13] 、仿⽣⽪肤 [14] 组织器官 [15] ,⽣化 [16] 与环境分析、单细胞分析 [17] 、核酸分析、药物筛选递送 [18] )。迄今为⽌,微型化、集成 化和智能化已经成为现代科技⼿段的⼀个重要趋势,在这样的⼤环境下微流控芯⽚的发展⼗分迅速,它的分 类⽅法丰富多样,可根据不同的分析检测⽅法可以将微流控芯⽚分为电化学检测法 [19] 、光谱分析法(核磁共 振 [20] 、化学发光分析法 [21] )、⾮标记检测法 [22] ,分离富集 [8] 等。 微流控芯⽚是医学领域新⼀代床旁诊断(Point of care testing,POCT) [23,24] 主流技术。POCT 可直接在被检 者身边提供快捷有效的⽣化指标,现场指导⽤药,使检测、诊断、治疗成为⼀个连续过程,对于疾病的早期 发现和治疗具有突破性的意义。基于微流控芯⽚技术的 POCT 仪器发展趋势是⼩型化、操作便捷,直接输⼊ 体液样本 [25] ,即可迅速得到诊断结果 [26] ,由医⽣指导⽤药。⽬前,市场上有多种即时诊断⽅法,仅有简单地 流动测试⼯作没有流体管理技术,⽽当测试复杂性增加时,微流控技术是⼀⻔不可或缺的技术。在治疗肿瘤 癌症的医疗领域⽅⾯,微流控技术同样⼤放异彩,如何使药物特异性杀死肿瘤细胞⽽不伤害正常细胞,这⼀ 直是个业界难题,代尔夫特理⼯⼤学 Jan H. van Esch 的课题组 [27] 将微流控设备中搭载⼀种具有双重功能的新 ⽉形微凝胶,研究发现这些微凝胶对肺癌细胞有⾼亲和、⾼选择性,可以达到肺癌化疗的效果并且减轻副作 ⽤对⼈体的伤害。微流控细胞/组织/器官操作芯⽚是哺乳动物细胞以及微环境操作最重要的技术平台,渴望 应⽤于代替各类动物模型,模拟⼈体内环境(⼈体、组织芯⽚ [28] ),⽤于药物筛查递送,研究药物毒理和药 理作⽤,⼈体耐药性 [29] [30] .
