• radicals whose formation is catalyzed from silver ions generated after uptake of silver by phagocytosis [110]. In contrast to chemical modifications of genomic DNA by reactive oxygen species (ROS) which are difficult to prove, the presence of DSB that result from a radical attack are more easily to detect

• oxidized under harsh conditions to yield exfoliated graphene oxide sheets that are soluble in aqueous media and amenable to chemical modifications due to the presence of carboxylic acid groups at the edges of the lattice. However, it was obvious that the high-defect framework of graphene oxide cannot be

• photocatalysts is a well-established method which gives access to materials for which light absorption, catalytic activity and selectivity can be tuned by structural and chemical modifications [1][2][3][4][5][6]. Prime examples for this approach are molecular metal oxides, so-called polyoxometalates (POMs) [7][8

• conductivity, and the uniformly long length. However, practical uses of VA-CNTs are limited by their surface characteristics, which must be often modified in order to meet the specificity of each particular application. The proposed approaches are based on the chemical modifications of the surface by

• deposition of V2O5 on the sidewalls of the tubes. Opening the tips facilitates the penetration of the electrolyte inside the composite electrode. Oxygen-based functionalization by plasma techniques can lead to morphological and chemical modifications of the nanomaterials [102][103] (Figure 10

• available molecular wires [22][23]. Second, the electrical properties of the OPE derivatives can be varied significantly by relatively minor chemical modifications [1][13][17][24][25]. In particular, a nonfunctionalized OPE-type molecule behaves as a molecular rectifier [23], whereas, when functionalized in
