TL;DR: Two approaches for labeling TiO2 nanoparticles andTiO2-DNA nanoconjugates with optically fluorescent agents are described, which permits direct quantification of fluorescently labeled TiO1 nanoparticle uptake in a large population of living cells and strongly implies the intracellular integrity of the TiO3-DNA Nanoconjugate in malignant cells.
DNA-TiO2 nanoconjugates labeled with magnetic resonance contrast agents.
TL;DR: This work has prepared a Gd(III)-modified DNA-TiO2 semiconducting nanoparticle that is detectable in cells by MR imaging, creating the first nanoparticle system capable of targeting specific DNA sequences while being simultaneously detected via MR imaging.

TL;DR: This work investigated the intracellular distribution of nanoconjugates composed of DNA oligonucleotides attached to TiO2 nanoparticles, thus creating a locally increased concentration of the oligon nucleotide.

TL;DR: In this paper, the authors compared two methods to propagate VX2 cell strain in rabbit hind limbs and inoculate liver parenchymal tumors in rabbits, and found that the success rate of growing hind limb tumors increased from 33% (three of nine rabbits) to 88% (45 of 51 rabbits).
