Copper speciation and toxicity in aquatic systems, and the fundamental basis of the Biotic Ligand Model (BLM). The free copper ion (Cu 2 +) is the most bioavailable species interacting with the target sites of the biological ligand.Cu 2+ has a tendency to form complexes with both inorganic and organic ligands, which significantly reduces its toxicity.
The interaction of ligands with their binding sites can be characterized in terms of a binding affinity. In general, high-affinity ligand binding results from greater attractive forces between the ligand and its receptor while low-affinity ligand binding involves less attractive force. In general, high-affinity binding results in a higher occupancy of the receptor by its ligand than is the case for low-affinity … WebMay 8, 2024 · Targeting nanoparticle (NP) carriers to sites of disease is critical for their successful use as drug delivery systems.
