Polymer control of ligand display on gold nanoparticles for multimodal switchable cell targeting.

چکیده
The function of cell-specific ligands on gold nanoparticles can be selectively gated by the action of co-grafted thermosensitive polymers. Below the LCST the responsive chain-extended polymers prevent cell-surface receptors from accessing the affinity ligands while above the LCST, the polymers collapse exposing the ligands and allowing binding to receptors, which in turn promotes cell internalisation.

Radiosensitization of breast cancer cells using AS1411 aptamer-conjugated gold nanoparticles
Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...
