  • CARBON NANOPARTICLES, WHICH ARE COVALENTLY BOUND VIA A BRIDGE MOLECULE TO A TARGET MOLECULE, AND A METHOD FOR THE PRODUCTION THEREOF
    Publication number: 20110112287
    Abstract: A method for covalently binding target molecules to carbon nanoparticles via at least one bridge molecule includes converting carbon nanoparticles to acyl carbon nanoparticles using a carbonyl compound of the at least one bridge molecule in the presence of a Lewis acid under Friedel-Crafts conditionsm, where the acyl carbon nanoparticles include a nucleofuge in the omega position. The target molecule is covalently bound to the acyl carbon nanoparticles via nucleophilic substitution of the nucleofuge in the omega position.

  • Ozone -induced gene expression in plants
    Publication number: 20050071899
    Abstract: The present invention relates to new DNA sequences, a method for producing new plants which contain a new DNA sequence, the coding sequence thereof being expressed after ozone induction. The invention also relates to said new plants and the use of DNA sequences to produce ozone-responsive gene expression in plants and plant cells. Moreover, it relates to a new promoter, the specificity thereof being increased by removal of the ozone response capacity thereof.
