The biosensor consists of two parts, the transducer and the biological recognition layer. The biological recognition layer is embedded with enzymes that recognize certain analytes. The transducer sends out a signal when analytes are recognized. These analytes are: Troponin T, Natriuretic peptides, Lipoproteins or cholesterol, and C-reactive protein. These analytes are all early indicators of heart disease or heart issues.


As the bot moves through the blood vessel, the biosensors will determine the level of the analytes in the blood. When an enzyme in the biological recognition layer recognizes an analyte, the transducer sends a signal to the controller that can then deliver the information to a smart device.
