Adsorption of Duplex DNA on Mesoporous Silicas:  Possibility of Inclusion of DNA into Their Mesopores

Abstract

In Table 2 of the paper, the correct value of SSA of sample G was 872 (m 2 /g), not 87 (m 2 /g).

Comparison and Optimization of Ancient DNA Extraction

“…Binding to silica is widely used when clean DNA is required or samples contain large amounts of chemical substances of a poorly understood chemical nature but which are known to inhibit PCR (6,20,22). Usually, chaotropic salts are used in order to bind DNA to a silica matrix (20,21), a process still not fully understood, but most likely resulting from the dehydration of both DNA and silica surfaces and hydrophobic forces acting under high salt concentrations (21,25). As several nonchaotropic salts are much cheaper than chaotropic salts, such as GuSCN or NaI, we tested, among others, NaCl in ancient DNA extraction.…”

Synthesis and characterization of bifunctional mesoporous silica adsorbent for simultaneous removal of lead and nitrate ions

“…Porous materials have been selected as the most potential bifunctional adsorbents because of their intrinsic high specific surface area and stable interconnected frameworks with an active pore surface for easy modification. 6 The preparation of mesostructured silicas since 1992 7 and to this date has diversified the field of applications in adsorption, 8,9 catalysis, 10 energy storage, 11 electrochemistry, 12 and biomedical engineering. 13 The most well-known representative of this class of material is MCM-41 (constituting an hexagonal arrangement).…”

A two-step route to synthesis of small-pored and thick-walled SBA-16-type mesoporous silica under mildly acidic conditions

“…[1][2][3][4][5][6][7][8]. Presently, besides M41S molecular sieves, a variety of the ordered mesoporous silica materials such as SBA, MSU, FDU, JLU, FSM, KIT have also been successfully synthesized with anionic, neutral, and nonionic surfactants through various assembly routes [9][10][11][12][13][14][15].…”
