Geometrical 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 کاملComputational design optimization for microfluidic magnetophoresis.
Current macro- and microfluidic approaches for the isolation of mammalian cells are limited in both efficiency and purity. In order to design a robust platform for the enumeration of a target cell population, high collection efficiencies are required. Additionally, the ability to isolate pure populations with minimal biological perturbation and efficient off-chip recovery will enable subcellula...

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 کاملAssessment of liquid microbead arrays for the screening of newborns for spinal muscular atrophy.
BACKGROUND Spinal muscular atrophy is a common neurodegenerative disorder that has recently been considered for inclusion in the next generation of newborn screening regimens. We sought to validate liquid microbead arrays for the identification of affected individuals by direct DNA analysis. METHODS Assays were created to detect the homozygous deletions in exon 7 of the SMN1 gene found in app...
