A sustainable aqueous-based route is reported for the synthesis of low density mesoporous silica/chitosan nanocomposite aerogels by cogelation of a chitosan biopolymer dissolved in silicic acid. The random “cluster–cluster” aggregate silica str

Chemical modification/ambient drying method and freeze drying method were introduced to research the synthesis of mesoporous silica aerogels. By analyzing N2 gas adsorption/desorption isotherms, the fractal geometric characteristics of gels were focu

A composite of a silica aerogel and a copolymer of chitosan and polyaniline (chitaline) with Au or Ag nanoparticles was prepared by a surfactant-free sol–gel process. By grafting polyaniline on the chitosan backbones, the copolymer chitaline was sy

In order to synthesize a carbon–metal or metal oxide combination sphere, carbonaceous resource furfural 1 was introduced, which was nucleophilic treated with 1,1′-dilithioferrocene 2 to form a sugar-organometallic compound: ferrocenyl monosacchar

The oxygen-sensitive ferrocenylacetic acid moiety was incorporated in a water-soluble DNA-damaging agent via the synthon 1,1′-ferrocenediacetic acid anhydride. The extent of plasmid nicking was pH-dependent, with complete cleavage at pH 5.5. The ni

The synthesis of an abasic PNA-based dimer block has been achieved. An alkyl chain stapling the two base sites conformationally restricts the PNA backbone, and serves as an example of preorganization by direct base site linkage. Other possible exampl

The effect of the universal base 3-nitropyrrole on the pairing selectivity of neighboring nucleosides has been determined for every combination of complementary and neighboring nucleosides. In a subset of cases the discriminatory ability of the neigh

Madin-Darby bovine kidney (MDBK) cells were treated with the bifunctional DNA cross-linker, L-7, to examine the generation of micronuclei and other nuclear abnormalities. The preceding paper demonstrates that L-7 treatment induces the formation of tr

The C-terminal amides of α-amino acids are readily hydrolyzed at 25° and pH 7 when the N-terminus is N-hydroxyethylated, with one or two hydroxyethyl groups. The reaction proceeds via cyclization to a morpholinolactone (2) which is rapidly hydrolyz

We have investigated the DNA binding properties of the anthramycin analogues 4, 5, and 6 using fluorescence spectroscopy. A considerable fluorescence enhancement occurs when pyrrolo [1,4] benzodiazepines (P[1,4]Bs) are covalently attached to duplex D
