The biocompatibility of the 3D printed poly(ethylene glycol) diacrylate hydrogel resin was conducted and had no observable effect on worm lifespans. Worm organ morphology was directly observable through the microfluidic device and low autofluorescence was demonstrated using genetically-modified pharynx fluorescent worms.

Commercially available resins (Monoprice Clear and formlabs Clear) and a custom polyethylene glycol diacrylate photopolymer resin was characterized using a critical angle determination method with a Pulfrich-based refractometer setup. The refractive indices ranged between 1.505 − 1.533 across the visible spectrum (670 − 405 nm, respectively), while the Abbe number ranged between 44.4 − 67.8.

A limit of detection at the single molecule detection level (10pM) and excellent specificity (single nucleotide mismatches) is observed.

We have demonstrated that these ARROWs can be used in sensing applications with single particle sensitivity using fluorescence correlation spectroscopy. To increase sensitivity for single molecule sensing, we have improved our initial designs and fabrication methods to decrease ARROW background fluorescence

These integrated platforms require that hollow waveguides interface with standard solid waveguides on the substrate to couple light into and out of test media. Previous designs required light at these interfaces to pass through the anti-resonant layers. We present a new ARROW design which coats the top and sides of the hollow core with only SiO 2 , allowing for high interface transmission between solid and hollow waveguides. The improvement in interface transmission with this design is demonstrated experimentally and increases from 35% to 79%. Given these parameters, higher optical throughputs are possible using single SiO 2 coatings when hollow waveguides are shorter than 5.8 mm.
