| dc.description.abstract | Nowadays, the number of people with diabetes has increased rapidly; thus the glucose biosensors have been developed and played an important role for glucose monitoring. Glucose biosensor with gold electrode was produced by CVD method which has high production cost.
The purpose of this study was to develop a process with electroless plating to make the glucose biosensor with gold electrode and to find the optimal process for three different substrates. The first substrate was produced by screen printing method using palladium as the catalyst, the second one was prepared by lithography method, and the last base material was made by copper-clad laminate.
All of the substrates with different methods were made by electroless plating method. The samples were characterized by X-ray photoelectron spectroscopy, adhesion test, cyclic voltammetry method. The results illustrated that three substrates with electroless plating can be used to produce the stripe. One substrate used by screen printing
method was reduced by reduction agent without sodium hypophosphite. Another substrate with lithography method needs to reinforce adhesion on PET. The base material made by copper-clad laminate easily used electroless plating to get final product. The optimum operation conditions of electroless reactors for nickel were at the range of temperature with 76 to 80 oC and dipping time with 5 min; palladium and gold were at temperature of 50 oC and 80 oC, respectively. The dipping time of palladium and gold was 3 min and 8 min, respectively. The thickness of nickel, palladium and gold were about 0.5 to 0.7 m, 0.02 m and 0.08 m, respectively. | en_US |
