Microfluidic Protein Preconcentrator Using a Microchannel-Integrated Nafion Strip: Experiment and Modeling

Martinus Gijs, Venkataragavalu Sivagnanam, Meng Shen

We propose a simple microfluidic device for protein preconcentration based on the electrokinetic trapping principle. It comprises a narrow Nafion strip that is simply cut from a commercial membrane and is integrated into a molded poly(dimethylsiloxane) (PD ...

Nonlinear optical properties of core-shell nanocavities for enhanced second-harmonic generation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

A nonlinear optical plasmonic core-shell nanocavity is demonstrated as an efficient, subwavelength coherent light source through second-harmonic generation. The nonlinear optical plasmonic nanocavity incorporates a noncentrosymmetric medium, which utilizes ...

A fixed-volume microfluidic mixer realized using multilayer PDMS technology

Martinus Gijs, Hüseyin Cumhur Tekin

We present leakage-free valves and an efficient fixed-volume mixer fabricated using a four-layer soft lithography technique in polydimethylsiloxane (PDMS). Mixing is achieved with a 95% efficiency in a few seconds by creating circular flow patterns inside ...

Integration of plasmonic trapping in a microfluidic environment

Olivier Martin, Sebastian Maerkl, Lina Huang

Near field generated by plasmonic structures has recently been proposed to trap small objects. We report the first integration of plasmonic trapping with microfluidics for lab-on-a-chip applications. A three-layer plasmo-microfluidic chip is used to demons ...

Optofluidic dye lasers

Demetri Psaltis

Optofluidic dye lasers are microfabricated liquid dye lasers enabled by the microfluidics technology. The integration of dye lasers with microfluidics not only facilitates the implementation of complete "lab-on-a-chip" systems, but also allows the dynamica ...

A compact optofluidic microscope

Demetri Psaltis

We demonstrate a novel optical imaging device that can be directly integrated into a microfluidic network, and therefore enables on-chip imaging in a microfluidic system. This micro imaging device, termed optofluidic microscope (OFM) is free of bulk optics ...

How to measure χ(3) of a nanoparticle

Most of the known methods to measure the nonlinear optical properties of materials deal with the bulk properties, but there are many demanding applications that require those measurements to be done on a single particle or a single molecule. We report a no ...

Nonlinear optics of molecular nanostructures in solution: Assessment of the size and nonlinear optical properties

Dmitri Ivanov

Most of the known self-assembly processes occur in solution, where nanosized objects interact each other forming new structures. Their real-time characterization in terms of the size and optical properties of these objects is vital for understanding those ...
