High-throughput On-chip Dna Fragmentation

In this paper we report a high throughput clog-free microfluidic deoxyribonucleic acid (DNA) fragmentation chip that is based on hydrodynamic shearing. Genomic DNA has been reproducibly fragmented with 2-10 kbp fragment lengths by applying hydraulic pressure ΔP across micromachined constrictions in the microfluidic channels. The utilization of a series of constrictions reduces the variance of t...

Automated high-throughput cell microsurgery on-chip.

Laser cell kill is an established tool for studying cells' roles during development and behavior, but its use has been limited due to the manual and low-throughput nature. We demonstrate here a technique combining multiplexing microfluidic manipulation of Caenorhabditis elegans and software for image processing and automation, allowing for high-throughput cell ablations.

Reusable platforms for high-throughput on-chip temperature gradient assays.

This paper describes a reusable platform that can apply a linear temperature gradient to a lab-on-a-chip device. When a planar microfluidic device with a series of microchannels is placed on top of the platform with the channels perpendicular to the gradient, each channel is held at a discrete temperature. This allows temperature-dependent data for chemical or biochemical species flowed into th...

Handheld high-throughput plasmonic biosensor using computational on-chip imaging

We demonstrate a handheld on-chip biosensing technology that employs plasmonic microarrays coupled with a lens-free computational imaging system towards multiplexed and high-throughput screening of biomolecular interactions for point-of-care applications and resource-limited settings. This lightweight and field-portable biosensing device, weighing 60 g and 7.5 cm tall, utilizes a compact optoel...
