| Abstract Scope |
Semiconductor nanomaterials, also known as quantum dots, have generated a lot of interest in different applications over the past decades. However, the toxicity of the binary-based quantum dots has brought about a big shortcoming in their applications. Hence, the need for non-toxic quantum dots. In this paper, we report the synthesis of ternary quantum dots for the instant degradation of organic pollutants in contaminated water and their conjugation to porphyrin as a dual phototherapeutic agent against cancer. The results showed that the QDs instantly degrade the organic pollutant in both deionised water and river with an efficiency of 99.94% and 95.79% for methylene blue and rhodamine 6G. Furthermore, the QDs-porphyrin conjugates exhibited higher singlet oxygen and photothermal profiling with a high percentage of cell death compared to the bare QDs and porphyrin against cancerous cells. |
