Abstract

This paper describes a pumping technique applicable to centrifugal microfluidic platforms, involving the use of a regulated stream of compressed gas to pump liquid radially inward and toward the center of the platform while spinning. This technique provides a noncontact method for pumping fluids and is highly efficient, requiring only approximately 60 s to reach completion. This pumping operation can be attained with an applied gas flow rate of 58.8 L min(-1), while the platform is rotated at frequencies less than 180 rpm (3.0 Hz).

摘要

本文介绍了一种适用于离心微流控平台的泵送技术，涉及使用受控的压缩气体流将液体径向向内并朝向平台中心泵送，同时进行旋转。该技术提供了一种非接触式泵送液体的方法，效率非常高，仅需大约 60 秒即可完成。这种泵送操作可以在施加的气体流速为 58.8 L min(-1)的情况下实现，同时平台以小于 180 rpm（3.0 Hz）的频率旋转。
