Organic letters, 4(14), 2329-2332 (2002-07-06)

[reaction: see text] The reaction of symmetrical diols and oligo(ethylene glycol)s with a stoichiometric amount of p-toluenesulfonyl chloride in the presence of silver(I) oxide and a catalytic amount of potassium iodide led selectively to the monotosylate derivatives in high yields.

Amorphous silica nanoparticles do not induce cytotoxicity, cell transformation or genotoxicity in Balb/3T3 mouse fibroblasts.

Chiara Uboldi et al.

Mutation research, 745(1-2), 11-20 (2011-11-19)

Although amorphous silica nanoparticles (aSiO(2)NPs) are believed to be non-toxic and are currently used in several industrial and biomedical applications including cosmetics, food additives and drug delivery systems, there is still no conclusive information on their cytotoxic, genotoxic and carcinogenic
