摘要

微流体数字化喷点技术可对低粘度液体的单次喷射体积进行精确的控制，样点直径的变异系数小于8%。不同于现有的微喷点技术，微流体数字化喷点技术具有无热源、无可动件、无外部加压装置、结构简单的特点。本文针对不同粘度的低粘度液体和驱动参数进行了微喷点基础实验研究，并采用微流体数字化喷点技术制作了样点直径在100μm左右的中等密度的微阵列。

Abstract

Dispensing technology of digitalization of microfluids can control the volume of a droplet precisely per dispensation

using the low viscosity liquids. The coefficient of variation (CV) for diameters of spots is clearly below the measurement error (8%). Different with the existing technologies

dispensing technology of digitalization of microfluids has some special advantages

such as: no heat resource

no movable parts

no pneumatic actuator

and no complicated configuration. The basal experiments are done

using the different low viscosity liquids and driven parameters. Finally

the medium-density microarray is accomplished

and the average diameter of spots is about 100μm.
