How are Nanoparticles Used in Biochemical Analysis?
Nanoparticles, such as gold nanoparticles and quantum dots, are commonly used to detect biochemical analytes. These nanoparticles can be functionalized with specific recognition molecules like antibodies, aptamers, or enzymes that selectively bind to the target analyte. Upon binding, changes in optical, electrical, or magnetic properties of the nanoparticles can be measured, allowing for sensitive and specific detection.
