Modulating DNA adsorption on silica beads using an electrical switch.
نویسندگان
چکیده
We demonstrate active tuning of DNA adsorption on silica beads using an electrical switch in a microfluidic device; we use electrolysis of water to alter pH in a packed bed of silica beads and switch the silica bead surface between being adsorptive and desorptive for DNA molecules.

Surface Aggregate Structure of Nonionic Surfactants on Silica Nanoparticles
The self-assembly of two nonionic surfactants, pentaethylene glycol monododecyl ether (C12E5) and n-dodecyl-ß-maltoside (ß-C12G2), in the presence of a purpose-synthesized silica sol of uniform particle size (diameter 16 nm) has been studied by adsorption measurements, dynamic light scattering and small-angle neutron scattering (SANS) using a H2O/D2O mixture matching the silica, in order to hig...
متن کاملToward a microchip-based solid-phase extraction method for isolation of nucleic acids.
A silica-based solid-phase extraction system suitable for incorporation into a microchip platform (nu-total analytical system; nu-TAS) would find utility in a variety of genetic analysis protocols, including DNA sequencing. The extraction procedure utilized is based on adsorption of the DNA onto bare silica. The procedure involves three steps: (i) DNA adsorption in the presence of a chaotropic ...
متن کاملInteractions between dissolved natural organic matter and adsorbed DNA and their effect on natural transformation of Azotobacter vinelandii.
To better understand gene transfer in the soil environment, the interactions between dissolved natural organic matter (NOM) and chromosomal or plasmid DNA adsorbed to silica surfaces were investigated. The rates of NOM adsorption onto silica surfaces coated with DNA were measured by quartz crystal microbalance (QCM) and showed a positive correlation with carboxylate group density for both soil ...
متن کاملAdsorption and elution characteristics of nucleic acids on silica surfaces and their use in designing a miniaturized purification unit.
We report nucleic acid (NA) adsorption isotherms and elution profiles for silica surfaces and use these to design a miniaturized NA purification unit based on solid-phase extraction with silica beads. The procedure is based on a pressure drop equation for flow through a packed bed and allows estimation of key design parameters such as channel dimensions, liquid flow rates, sample volume, and am...
متن کاملEnd-specific covalent photo-dependent immobilisation of synthetic DNA to paramagnetic beads.
A novel approach for light-dependent covalent immobilisation of synthetic DNA oligomers to amino-coated paramagnetic beads is described. A hetero-bifunctional photo-reactive cross-linking chemical, 4-nitrophenyl 3-diazopyruvate, is applied to attach 5' amino-modified DNA to both silica and polystyrene paramagnetic beads. The coupling yields are comparable with similar methods in which no photo-...
