Abstract
A robust and reliable liquid transport in a lab-on-chip analytical device is highly desirable. In this study, we present a versatile microfluidic platform based on a micropillar array. Fluid flow is driven by evaporation, and yetphotometric analysis on the platform is insensitive to ambient conditions such as temperature and humidity. A signal enhancement effect is also demonstrated when conducting analysis on the platform. The signal enhancement agrees well with a deduced theoretical model showing its independency from both temperature and humidity.
