Recently, point-of-care diagnostics has gained great attention because it can improve patient's quality of life. Electrochemical diagnostic systems are promising because of their miniaturizability and low-cost. However, fabrication of such devices requires special skills as well as expensive equipment and supplies. This thesis is based on a research project aimed at fabricating electrochemical sensors combing wax printing and inkjet printing or wax printing and hand painting. The electrochemical sensors can be used for measuring different kinds of electrochemical analytes like dopamine, uric acid by electrochemical methods like amperometry, which can show great calibration curve. The LOD of dopamine, uric acid, ascorbic acid, Nile Blue, hydrogen peroxide and ferrocene is 0.015 μM, 7.3 μM, 30 μM, 1.3 μM, 8 nM and 30 μM, respectively. Further, we can modify the electrochemical sensor by using multiwall carbon nanotube in order to improve the sensitivity of the electrochemical sensors. This modified electrochemical sensor can also be used as immunoassay by sandwich format ELISA for detecting carcinoembryonic antigen (CEA), which has been designated as a reliable biomarker for several types of cancers. We found that the CNT modified hand-painting device can detect CEA down to 0.6 ng/mL, which is three times lower than the cut-off value of diagnosis, i.e. 5 ng/mL in blood.

The development of radioimmunoassay (RIA) by R.S. Yalow and S.A. Berson in 1959 opens up a new avenue in ultra sensitive analysis of trace substances in complex biological systems. In recognition of the enormous contributions of RIA to basic research in biology and to routine clinical tests in laboratory medicine, R.S. Yalow, the co-developer of RIA, was awarded, in 1977, the Nobel Prize for Medicine and Physiology. The basic principle of RIA is elegantly simple. It is based on a specific, competitive binding reaction between the analyte and the radio-labeled analog of the analyte for the specific antibody raised to the analyte. The combination of high specificity and affinity of an antibody molecule makes it a very versatile analytical reagent capable of reacting specifically with analytes at a very low concentration in a complex solution such as serum. The sensitivity of RIA is provided by using a radioactive tracer.
