How Does Surface Charge Density Affect Nanomaterials?
Surface charge density can significantly influence the behavior of nanomaterials in various ways:
Stability: High surface charge densities can stabilize nanoparticles in suspension by preventing aggregation through electrostatic repulsion. Reactivity: The surface charge can affect the chemical reactivity and interaction with other molecules or ions. Toxicity: Surface charge plays a role in the interaction of nanoparticles with biological systems, impacting their toxicity and cellular uptake. Self-assembly: Charged surfaces can drive the self-assembly of nanostructures through electrostatic interactions.
