Targeting ligands

Definition

Targeting ligands are specialized molecules that bind selectively to specific receptors on the surface of cells, often used to deliver therapeutic agents directly to diseased tissues. These ligands enhance the efficacy of radiopharmaceuticals by ensuring that radioactive isotopes are delivered precisely to target cells, minimizing damage to healthy tissues and improving treatment outcomes.
