A novel sandwich electrochemical immunoassay was developed for ultrasensitive detection of avian leukosis virus subgroup J (ALVs-J) using graphene quantum dots (GQDs) and apoferritin-encapsulated Cu (Cu-apoferritin) nanoparticles for signal amplification. GQDs were used both for the conjugation of primary ALVs-J
