An automated flow assembly for a biosensor has been developed in this paper. In recent years there has been a growing interest in the field of in-vivo biosensors for continuous monitoring. For this continuous monitoring of biological interactions, a need for the development of auto-flow assembly arises. The automated flow assembly inherently coupled to a biosensor forms a Flow Injection Analysis (FIA) system. The designed auto-flow assembly consists of three micro-fluidic solenoid valves actuated through a microcontroller AT89C51. A programmable turn-on time for each valve can be entered through a 4x3 keypad and its switching can be controlled by the microcontroller.
