متن کاملElectric field directed assembly of high-density microbead arrays.
We report a method for rapid, electric field directed assembly of high-density protein-conjugated microbead arrays. Photolithography is used to fabricate an array of micron to sub-micron-scale wells in an epoxy-based photoresist on a silicon wafer coated with a thin gold film, which serves as the primary electrode. A thin gasket is used to form a microfluidic chamber between the wafer and a gla...
متن کاملGeometrical optimization of microstripe arrays for microbead magnetophoresis.
Manipulation of magnetic beads plays an increasingly important role in molecular diagnostics. Magnetophoresis is a promising technique for selective transportation of magnetic beads in lab-on-a-chip systems. We investigate periodic arrays of exchange-biased permalloy microstripes fabricated using a single lithography step. Magnetic beads can be continuously moved across such arrays by combining...
متن کاملProfiling antibodies to Mycobacterium tuberculosis by multiplex microbead suspension arrays for serodiagnosis of tuberculosis.
Tuberculosis (TB) is a serious global disease. The fatality rate attributed to TB is among the highest of infectious diseases, with approximately 2 million deaths occurring per year worldwide. Identification of individuals infected with Mycobacterium tuberculosis and screening of their immediate contacts is crucial for controlling the spread of TB. Current methods for detection of M. tuberculos...
متن کاملOn-chip Protein Assays Using Microbead Arrays: an Integrated System for Salivary-based Clinical Diagnostics
A microfluidic device containing arrays of microwells filled with microbead sensors was used to perform protein assays in a saliva sample. Techniques for the fabrication of fully integrated arrays of microwells within polydimethylsiloxane (PDMS) microchannels were demonstrated. Subsequent microwell loading with stochastic arrays of encoded microbeads was performed and the devices were used for ...
