Lab-in-a-tube: on-chip integration of glass optofluidic ring resonators for label-free sensing applications†
Abstract
The fabrication of tubular rolled-up optofluidic ring resonators (RU-OFRRs) based on glass (SiO2) material with high quality factors is reported. A novel methodology combining lab-on-a-chip fabrication methods and rolled-up nanotech is presented for the fabrication of fully integrated tubular optofluidic sensors. The microfluidic integration of several RU-OFRRs on one chip is solved by enclosing the microtubes with a patterned robust SU-8 polymeric
