Abstract:

Porphyrins are photosensitisers (PSs) used in Photo Dynamic Therapy (PDT) due to their tumor localisation and in situ singlet oxygen generation. However, their limited absorption, insolubility and aggregation in aqueous medium limited their effective application in PDT. In this presentation, a large scale aqueous synthesis of CuInS2/ZnS core-shell, ternary quantum dots (QDs) and its conjugation to 5, 10, 15, 20-meso (4-hydroxyphenyl) porphyrin as an efficient way to overcome photosensitizer shortcoming will be discussed. The singlet oxygen generation of this highly aqueous soluble novel conjugate and its cell viability, which shows its potential for PDT applications will also be discussed.
