Abstract

We have developed methods for flow control, electric field alignment, and readout of colloidal Nanobarcodes{copyright}. Our flow-based detection scheme leverages microfluidics and alternate current (AC) electric fields to align and image particles in a well-defined image plane. Using analytical models of the particle rotation in electric fields we can optimize the field strength and frequency necessary to align the particles. This detection platform alleviates loss of information in solution-based assays due to particle clumping during detection.

Microfluidic System for Solution Array Based Bioassays

Technical Report Dougherty, G; Tok, J; Pannu, S; ...

The objective of this project is to demonstrate new enabling technology for multiplex biodetection systems that are flexible, miniaturizable, highly automated, low cost, and high performance. It builds on prior successes at LLNL with particle-based solution arrays, such as those used in the Autonomous Pathogen Detection System (APDS) successfully field deployed to multiple locations nationwide. We report the development of a multiplex solution array immunoassay based upon engineered metallic nanorod particles. Nanobarcodes{reg_sign} particles are fabricated by sequential electrodeposition of dissimilar metals within porous alumina templates, yielding optically encoded striping patterns that can be read using standard laboratory microscope optics andmore »« less

Lateral flow microarrays: a novel platform for rapid nucleic acid detection based on miniaturized lateral flow chromatography

Journal Article Carter, D.; Cary, R. - Nucleic Acids Research

Widely used nucleic acid assays are poorly suited for field deployment where access to laboratory instrumentation is limited or unavailable. The need for field deployable nucleic acid detection demands inexpensive, facile systems without sacrificing information capacity or sensitivity. Here we describe a novel microarray platform capable of rapid, sensitive nucleic acid detection without specialized instrumentation. The approach is based on a miniaturized lateral flow device that makes use of hybridization-mediated target capture. The miniaturization of lateral flow nucleic acid detection provides multiple advantages over traditional lateral flow devices. Ten-microliter sample volumes reduce reagent consumption and yield analyte detection times, excludingmore »« less

Surface enhanced Raman spectroscopy for microfluidic pillar arrayed separation chips

Journal Article Taylor, Lisa; Kirchner, Teresa; Lavrik, Nickolay; ... - Analyst, The

Numerous studies have addressed the challenges of implementing miniaturized microfluidic platforms for chemical and biological separation applications. However, the integration of real time detection schemes capable of providing valuable sample information under continuous, ultra low volume flow regimes has not fully been addressed. In this report we present a chip based chromatography system comprising of a pillar array separation column followed by a reagent channel for passive mixing of a silver colloidal solution into the eluent stream to enable surface enhanced Raman spectroscopy (SERS) detection. Our design is the first integrated chip based microfluidic device to combine pressure driven separationmore »« less

Centrifugal microfluidic platform for ultrasensitive detection of botulinum toxin

Journal Article Koh, Chung; Schaff, Ulrich; Piccini, Matthew; ... - Analytical Chemistry

In this study, we present an innovative centrifugal microfluidic immunoassay platform (SpinDx) to address the urgent biodefense and public health need for ultrasensitive point-of-care/incident detection of botulinum toxin. The simple, sample-to-answer centrifugal microfluidic immunoassay approach is based on binding of toxins to antibody-laden capture particles followed by sedimentation of the particles through a density-media in a microfluidic disk and quantification by laser-induced fluorescence. A blind, head-to-head comparison study of SpinDx versus the gold-standard mouse bioassay demonstrates 100-fold improvement in sensitivity (limit of detection = 0.09 pg/mL), while achieving total sample-to-answer time of <30 min with 2-μL required volume of themore »« less

Automated Sample Preparation method for suspension arrays using renewable surface separations with multiplexed flow cytometry fluorescence detection

Journal Article Grate, Jay; Bruckner-Lea, Cindy; Jarrell, Ann; ... - Analytica Chimica Acta

In this paper we describe a simple method for forming a renewable filter within a microfluidic system and demonstrate its use for capturing chemically selective beads that are too small to be easily captured in previous flow cells for renewable separation columns. The renewable filter is created by trapping larger beads in a flow cell. Smaller beads are then captured either within or on top of the bed of larger beads. A renewable filter created with 19.9 um beads was used to trap 5.6 um optically encoded beads in a sequential injection renewable separation column (SI-RSC). Both the selective microspheresmore »« less
