Cover Story: Prostate cancer is responsible for around 7.3% of cancer deaths in men. However, when detected early, the survival rate increases in almost 100% of patients. Techniques such as rectal examination and measuring the PSA level in the blood are used to detect cancer, but they have low specificity and sensitivity. Studies have revealed that Stanniocalcin-1 (STC-1) can be used as a biomarker for prostate cancer. In this work, four different STC-1 antibody sensors from a fish were deposited on interdigitated gold electrodes using layer-on-layer thin film preparation and self-assembly techniques. The detection of different STC-1 antigen concentrations was performed using impedance spectroscopy. The electrical characterization of the films was carried out using principal component analysis to validate them as effective sensors. View this paper
