Abstract

We developed a novel method that uses water droplets as molds to fabricate large arrays of highly curved microlenses. The formation of water droplets is controlled by creating circular hydrophilic regions on a hydrophobic surface with microscale PLasma Activated Templating (µPLAT) [1-3], in which a physical mask is used to expose selected areas to air plasma to increase hydrophilicity. The new method dramatically improves the light gathering capacity of microlenses over traditional microfabrication methods with a minimum cost. These lens arrays can be easily integrated with lab-on-a-chip devices.
