Fabrication and Performance of a Photonic-Microfluidic Integrated Device

Fabrication and performance of a functional photonic-microfluidic flow cytometer is demonstrated. The devices are fabricated on a Pyrex substrate by photolithographically patterning the microchannels and optics in a SU-8 layer that is sealed via a poly(dimethylsiloxane) (PDMS) layer through a unique chemical bonding method. The resulting devices eliminate the free-space excitation optics throug...

Control and automation of multilayered integrated microfluidic device fabrication.

Integrated microfluidics is a sophisticated three-dimensional (multi layer) solution for high complexity serial or parallel processes. Fabrication of integrated microfluidic devices requires soft lithography and the stacking of thin-patterned PDMS layers. Precise layer alignment and bonding is crucial. There are no previously reported standards for alignment of the layers, which is mostly perfo...

A method for detecting forward scattering signals on-chip with a photonic-microfluidic integrated device

A photonic integrated microfluidic device is demonstrated to perform optical excitation and forward scatter collection all on-chip in a planar format. Integrated on-chip optics formed a tailored beam geometry for optimal excitation of particles while a special design modification allowed for on-chip forward collection with the beam shaping capabilities. A notch was placed in the lens system tha...

Fabrication of Integrated Graphene Photonic Devices

Graphene is a single-atom-thick layer of carbon atoms in a honeycomb lattice. It is currently a popular material for study in condensed matter physics and related fields [1-6]. The material has a large number of proposed potential applications including integrated photonic devices. Saturable absorption and photocurrent generation has already been successfully demonstrated [1,2]. We aim to study...
