What are the Advantages of Using Gold Nanoparticles in Sensors?
Gold nanoparticle-based sensors offer several key advantages:
High sensitivity - Due to their strong LSPR effect, AuNPs can detect very low concentrations of analytes. Selectivity - Functionalization of AuNPs with specific ligands or antibodies allows for targeted detection of specific molecules. Stability - Gold is chemically inert, providing long-term stability to the sensors. Scalability - AuNPs can be produced in large quantities using simple methods.
