Disposable sensors are essential for biomedical analysis. Therefore, paper based sensors may became a good alternative to expensive tools and methods used to date in clinical laboratories. New stochastic sensors based on carbon thin films deposited on adsorbent and glossy papers modified with nanostructured material such as 5,10,15,20-tetrapheny1-21H,23H-porphyrin were proposed. Carcinoembryonic antigen a biomarker very often used for cancer diagnosis as well as for follow up of cancer treatment, was selected as model analyte. Qualitative and quantitative assay was performed using the new proposed sensors. The sensors can be used as disposable sensors for biomedical analyses with high reliabilities.
