Resumen
Microfluidics has attracted widespread interest in the fields of chemicals, materials, pharmaceuticals, biology, etc. Integrating low-cost automation based on open-source hardware/software to improve lab security and reduce time consumption is demanded in microchemical processing. In this work, we developed a “do it yourself” multichannel syringe pump by using easily available low-cost components and microcontrollers, which can be used for educational and/or research purposes in the study of microfluidics and flow chemistry. An Arduino UNO board with CNC shield expansion board and A4988 stepper motor driver is used to control the injection volume and rate of the four syringes. The Arduino-based open-source community minimizes the technical knowledge required to build the system and makes it readily shareable. Detailed fabrication guidelines are provided for the device, which is priced well below commercial alternatives and promotes the development of open hardware for microprocess engineering. The operation of the syringe pump can be controlled by the Arduino IDE or other software through the serial port, which is very beneficial for integration with other devices. Moreover, this multichannel syringe pump is also programmable and can be automatically operated. In order to verify the utility of the platform, we have carried out relevant demonstration experiments of microcapsule preparation for functioning cosmetic product and droplet generation based on microfluidic technique. From an educational point of view, students in the lab have the opportunity to learn how to design and build chemistry experimental devices from principles and demands in a hands-on learning environment, preparing them to work in modern and intelligent laboratories.
