This paper reports a novel microfluidic-chip based platform using "phase-transfer magnetophoresis" enabling continuous biomolecule processing. As an example we demonstrate for the first time continuous DNA extraction from cell lysate on a microfluidic chip. After mixing bacterial Escherichia coli culture with superparamagnetic bead suspension, lysis and… (More)
We present a continuous-flow active micromixer based on channel-wall deflection in a polydimethylsiloxane (PDMS) chip for volume flows in the range up to 2 μL s −1 which is intended as a novel unit operation for the microfluidic Braille pin actuated platform. The chip design comprises a main microchannel connected to a series of side channels with dead ends… (More)
The stereocontrolled synthetic procedure for the preparation of 2,4,5-trisubstituted 2,5-chiral 1,2,5,6-tetrahydropyridines was established using a one-pot asymmetric azaelectrocyclization protocol; the generality of this protocol was demonstrated by synthesizing the title compounds with various aryl and alkenyl substituents at the C-2 position.
Massively parallel and individual DNA manipulation for analysis has been demonstrated by designing a fully self-assembled molecular system using motor proteins. DNA molecules were immobilized by trapping in a polyacrylamide gel replica, and were digested by a restriction enzyme, XhoI, for DNA analysis. One end of the lambdaDNA was modified with biotin and… (More)
