In this work, a facile and efficient approach has been demonstrated for size-selective
separation of DNA fragments by using lysine-functionalized silica particles. At a given pH …

In this study, we investigated the distribution behavior of single-stranded DNA molecules
with 20 bases in silica particles (particle size:∼ 30 μm) using confocal fluorescence …

The high water-solubility and the biochemical instability of DNA have been serious problems
in applying DNA as a practical material. Improvement of these weak points would encourage …

Monodisperse silica microspheres with bimodal pore-size distribution were proposed as a
high performance sorbent for DNA isolation in batch fashion under equilibrium conditions …

Solid phase extraction and purification of DNA from complex samples typically requires
chaotropic salts that can inhibit downstream polymerase amplification if carried into the …

Magnetic separation has great advantages over traditional bio-separation methods and has
become popular in the development of methods for the detection of bacterial pathogens …

In this paper we report a novel DNA‐enrichment technology based on amino‐modified
functionalized silica nanoparticles. The approach takes advantage of the amino‐modified …

DNA extraction from clinical samples is commonly achieved with a silica solid phase
extraction column in the presence of a chaotrope. Versions of these protocols have been …

In the presence of sodium chloride (NaCl), DNA fragments can be size‐selectively
separated by varying the final concentration of polyethylene glycol (PEG). This separation …

The adsorption of λ-DNA on like-charged silica particles and the resultant DNA-colloid
complex structures are examined microscopically in this work. Enhanced adsorption of …
