Detection of PSMA in human prostate cancer tissue. Detection of PSMA positive structures in prostate cancer tissue sections by immunohistochemical staining using anti-PSMA aptamer (PSMA apt)-conjugated AuNPs. As a negative control, AuNPs conjugated with miniStrep aptamer (miniStrep apt) were used. A polyclonal antibody directed against PSMA (PSMA pAb) was used as a positive control. Positive control was additionally stained with Haematoxylin and Eosin. Black arrows indicate specific staining, while white arrows flag unspecific binding.
