Microcontact printing (μCP) is aneasy andefficientway of producing patterns of self-assembledmonolayers (SAM) containing different functional groups. We have developed a simple and convenient μCP-based technique for the modification of a mica substrate with 3-aminopropyltriethoxysilane (APTES) and the micropatterning of proteins (chicken IgG and rabbit IgG) on the modified mica surface. Our approach provides a quick and easy way to produce protein patterns on solid surfaces. The printed immunoglobulin patterns were detected by exposing the substrate to solutions containing fluorescently labeled complementary anti-IgGs, and the formed immunoassays were studied using fluorescence microscopy.

设计并制备了一种新的具有分子探针功能的主体分子型非病毒载体-邻菲啰啉-β-环糊精衍生物主体分子（DZY-1），应用凝胶电泳法研究探讨了DZY-1与DNA相互作用及客体分子对该主体分子诱导DNA凝聚的影响；并进一步研究探讨了单一主体分子、主/客体分子配合物诱导DNA分子凝聚和聚合所形成的超分子聚合物抗限制性内切酶（HindⅢ）酶解的特性. 应用扫描电子显微镜（SEM）观测到该主体分子、主/客体分子配合物与DNA分子相互作用形成超分子聚合物的微观结构形态。阐述了其作为非病毒基因载体可能的传递机制，为设计、制备新的非病毒基因载体提供了一种新途径。

微流控芯片最初起源于分析化学领域，是一种采用精细加工技术，在数平方厘米的基片，制作出微通道网络结构及其它功能单元，以实现集微量样品制备、进样、反应、分离及检测于一体的快速、高效、低耗的微型分析实验装置。随着微电子及微机械制作技术的不断进步，近年来微流控芯片技术发展迅猛，并开始在化学、生命科学及医学器件等领域发挥重要作用。本文首先简单介绍了微流控芯片制作材料和工艺，然后主要阐述了其在蛋白质分离、免疫分析、NDA分析和测序、细胞培养及检测等方面的应用进展。
