What is a microfluidic chip?

Microfluidic chips are devices used in studies in which micro-channels have been molded or patterned. The channels forming the chip are connected together to allow fluids to pass through different channels, going from one place to another. This network is connected to the outside environment through inlet and outlet ports.

The liquids (or gases) are injected, managed, and/or removed from the chip passively or actively (pressure/flow controller, syringe pumps, or peristaltic pumps). The channels may have different inner diameters, typically ranging from 5 to 500 µm, but today structures can be fabricated with sub-micrometer precision.

The channel network must be specifically designed for the desired application and analysis (cell culture, organ-on-a-chip, DNA analysis, lab-on-a-chip, microfluidic droplets, etc.).

A bit of history

Miniaturization techniques have been continuously shaping the microelectronics technology and its ability to produce devices for a broad range of applications. Downscaling the dimensions of transistors have been pursued in the industry to fulfill the demand for smaller, faster and energy-efficient systems1. In the late 1960s, a new field named microelectromechanical systems (MEMS) emerged.

This laid the foundations for the miniaturization of mechanical systems, with the development of micromachining technology based on silicon semiconductor technology. That is when engineers began realizing that silicon chips could process things such as chemicals, motion, and light.

The first implementation of inkjet printer heads demonstrated that micron-sized droplets could be generated using piezoelectric or thermal effects. In 1990, Manz et al. introduced the concept of miniaturized total chemical analysis systems (μTAS)2.

Soon after, companies were founded to utilize these systems for life science applications. Rapid prototyping and replication of polymers (such as PDMS) as an alternative to silicon processing, accelerated academic research, and new terminologies such as “microfluidics” and “lab-on-a-chip” (LOC) emerged.

Chip manufacturers

Beonchip S. L. was founded in 2016 at the University of Zaragoza by Ignacio Ochoa (specialist and PhD in biology), Luis Fernández (PhD in microtechnology) and Rosa Monge (PhD in mechanical Engineering).

Therefore, Beonchip have multidisciplinarity in its roots, and their team is proof of that. The collaboration of engineers and biologists has been key to design the most user friendly and accessible organ on chip devices that are true to the physiological environment of the body.
