One of the most promising variants of targeted drug delivery is the use of nanoparticles as drug-carriers. In the stage of pre-clinical studies, the main goal is to visualize these particles, to control their destination and accumulation in living organism. Thus, it is convenient to use materials with controlled optical properties. Diamond nanoparticles (ND) are of considerable interest, due to their small size and labile surface. ND surface may be functionalized in various ways, which allows using them as a drug-carrier or conjugate them with fluorochrome for visualization. Our work presents model studies of complexes of nanodiamonds with tetracarboxyphenylporphyrin (TCPP) as a fluorescent agent.
