Microfluidic is the science technology in studying behaviour of fluids through micro-channels [1]. It minimizes the volume of fluids flow in a confined channel with the modern technology. The main idea of this project is to enhance the user-interface for controlling microfluidic system by designing a control interface to run syringe pump and study on the correlations between flow rate administer by the syringe pump and droplet formation. Syringe pump is a main component in the microfluidic systems as it provides channels to allow liquids to follow through the entire systems. It has been widely used in the medical industry in form of liquid injection. It replaced the previous of manual injection of liquids which requires labouring and accuracy. It is essential in microfluidic system in analysing liquid characteristics and properties as it provides a continuous of flowing liquids into the microfluidic system with limited volume. Currently, the application for controlling the syringe pump is inefficient and time consuming for user to control the system which consequently receiving inaccurate result. In this paper, entire work of designing a friendly user-interface to control main components for the microfluidic system is shown. The result and effect of the newly-built system has met all the conditions requested by the user. The newly-built function which can be used with most of the programmable syringe pump. Next, the fabrication of microfluidic chip using polydimethylsiloxane (PDMS) instead of silicon [2]. T-junction generator made in PDMS will be used as microfluidic chip. Microfluidic Chip, lab-on-chip is designed using AutoCAD software, consists of micro-confined channels, allowing fluids to follow through to achieve desired results such as detect if pathogens, electrophoresis and DNA analysis. Work place will be built for the experiment to takes place for the integration of syringe pump, being programmed by the software LabVIEW and the fabricated microfluid chip to study on the droplet formation stages and the effect of variant flow rate affects the length of the droplet.
