Early detection of tumor markers, which are usually proteins, can greatly facilitate effective treatment with different modalities and even increase cure rate of patients. Currently, nanoparticle-based methods for cancer diagnostics are becoming an increasingly relevant alternative to traditional techniques. Gold nanoparticles (AuNPs) are one of the most extensively studied nanomaterials due to their remarkable physical and chemical properties. With the recent advances in nanotechnology, AuNPs have offered new ways to detect tumor markers at low concentrations and to target cancer cells in very deep sites. The use of AuNPs may increase the sensitivity of a biosensor and generate higher accuracy and precision of the assays. So, AuNPs have greatly facilitated the development of nanomaterials-based technology for clinic diagnostics and therapy. In this review paper, we have summarized different kinds of AuNPs-based biosensors for the detection of tumor marker proteins with a particular focus on optical and electrochemical techniques, which may provide valuable perspective for the colleagues in the related communities.
