【摘要】 提出了一种利用CO2激光对聚甲基丙烯酸甲酯(PMMA)进行快速微加工,制作微阵列点样器的新方法。利用该微阵列点样器将多个样品平行同步地转移到尼龙膜基底上,形成微阵列芯片。微阵列点样器包含有48个间距为1500μm的6×8阵列式微通道,液体转移头内径为80μm。转移到基底上的样点平均半径为200μm,其样点直径相对标准偏差为2.45%。更多还原

【Abstract】 A new method to produce PMMA (polymethyl methacrylate) -based microarrayers rapidly by CO2 -laser was presented. The microarrayer can simultaneously spot hundreds to thousands of reagents into a microarray. The microarrayer has the 6×8 array of channels with 80μm diameter nozzles at a pitch of 1500μm. The radius of spots which were printed on substrate is about 200μm. And the CV of the spot diameters is 2. 45%.更多还原
