Carbon dots from an immunomodulatory plant for cancer cell imaging, free radical scavenging and metal sensing applications

Aim: This work aimed to develop Tinospora cordifolia stem-derived carbon dots (TCSCD) for cancer cell imaging, free radical scavenging and metal sensing applications. Method: The TCSCDs were synthesized by a simple, one-step, and ecofriendly hydrothermal carbonization method and characterized for their optical properties, morphology, hydrodynamic size, surface functionality, crystallinity, stability, bacterial biocompatibility, in vitro cellular imaging, free radical scavenging and metal sensing ability. Results: The TCSCDs exhibited excellent biocompatibility with dose-dependent bioimaging results in melanoma (B16F10) and cervical cancer (SiHa) cell lines. They exerted good free radical scavenging, Fe3+ sensing, bacterial biocompatibility, photostability, colloidal dispersion stability and thermal stability. Conclusion: The results reflect the potential of TCSCDs for biomedical and pharmaceutical applications.

Lanthanide clusters of phenanthroline containing a pyridine–pyrazole based ligand: magnetism and cell imaging

In this contribution, we report the synthesis, characterization and luminescence–magnetic properties of Ln-clusters (Ln = Gd3+, Eu3+ and Tb3+) using a new pyridine–pyrazole functionalized ligand fitted with a chromophoric phenanthroline backbone. We have applied the luminescence property of clusters for cancer cell imaging.
