Properties
Description
These silica nanoparticles feature a surface dense with carboxylic acid groups, providing a strong negative charge in neutral pH environments. The COOH groups serve as a versatile platform for conjugation with amine-containing species using carbodiimide chemistry (EDC/NHS). The particles are highly stable and resist non-specific binding, making them ideal for high-precision laboratory experiments.
