Sensing device for electrochemical analysis of biological materials

摘要

sensor for electrochemical analysis of biological materials, consisting of a substrate (6), a reference electrode (3), electrodes (2) and closing working electrodes and having an insulating layer (5),is characterised by having two tru00f3jwarstwowe working electrodes (1) in the form of two separated wheel diameter of 0.2 mm,around which is two layer electrode (2) in the form of a closing piece districtthe reference electrode (3) is in the form of the circle and is five times less than the closing electrodes (2), whereby the sensor has a single layer connector (4) in the form of fiveand in the central part of the four parallel lines connected to each of the electrodes. the ground plate (6) is in the form of rectangular size 35 x 10 x 0.5 mm, made from polymer.the first layer of the working electrodes (1) is made of silver, the second layer is made of a carbonaceous material elektroprzewodzu0105cego,and the third layer is made of a nanokompozytu in the form of reduced graphene oxide, nanoczu0105stkami clad with platinum. a connector (4) are lines width from 0.7 to 1.0 mm, made of silver.
