Fig. 3From: Development of gold nanoparticles biosensor for ultrasensitive diagnosis of foot and mouth disease virusThe dynamic light scattering of the naked AuNPs and AuNPs-FMDV biosensor: curve a demonstrates a peak of size distribution by number representing 13 nm of naked AuNPs. Curve b demonstrates a peak of size distribution by number showing slight increase in size due to the conjugation process representing 17–20 nm AuNPs-FMDV biosensorBack to article page
