摘要Point of care testing (POCT) based on biosensors has been recently received increasingly interesting in the world. Using biosensor technology for biomedical analysis has demonstrated many advantages. However, low cost and high accurate biosensors for clinical analysis, particularly for POCT is still a common problem for commercialization of the most biosensors[1, 2].In this work, it has the goals to develop materials (including nano materials) and methods for producing disposable biosensors capable with low cost, high reliability & sensitivity, robustness, low volume sample, and creating portable sensor systems (Figure 1) for testing human metabolites, biochemical markers without reagents. On top of the use of electrochemical method and Nano, MEMS technology, hemoglobin, creative kinase, alanine aminotransferas (ALT), Aspartate Aminotransferase (AST), glucose, lactate, ketone (β-Hydroxybutyrate), cholesterol have been tested using thin film electrode biosensors, modified with nanoporous and nanostructured materials (Figure 2). The electrxode has high surface-to-volume ratio and excellent hydrophilicity, thus the electrode possesses high catalytic activities for electrolytic processes and are ideal candidates for biosensors.It is significant for the applications in clinical diagnosis of diabetes, cardiovascular diseases, home health care,sports, physical performance of athletes, blood screen. Glycated hemoglobin, creatine kinase MB (CK-MB), myoglobin, cardiac tropenin I (cTnI), cardiac troponin T (cTnT) are interesting to be tested for the next study.
