For the implementation of the stated objective a device enabling real-time detection of small concentrations of proteins in specific liquid mediums was developed. An evaluation of biosensor sensitivity was performed experimentally with cardiac marker – C-reactive protein, which demonstrates an increase of concentration in all non-specific inflammatory reactions, including myocardial infarction and other acute cardiovascular accidents. A receptor layer was developed based on monoclonal antibodies, enabling specific binding of C-reactive protein, generating lateral strain in the layer. The feasibility of C-reactive protein detection in fluid flow using microcantilever sensors was demonstrated. To allow the possibility of sensor device implantation into oral cavity for continuous monitoring and early detection of diseases based on human saliva composition, a concept and prototype of microcapsule transducer was developed. The transducer constitutes a microaspirator pump with the feature of operator chamber rinsing, which provides circulation of biological fluid samples in the implanted device. https://www.biotech-asia.org/vol12no3/development-of-a-biosensor-for-the-prediction-and-early-detection-of-cardiovascular-diseases-based-on-saliva-composition-analysis/ cantilever sensor; saliva; cardiac markers; micropump; C-reactive protein; constant monitoring
