While we see significant advances in technology, it’s rare the opportunity we have to take a step back and consider how these feats were made. There’s a lot of ingenuity, planning, and dedication that goes into the design and fabrication of these components. Follow along as we go into the fabrication methods for microfluid components.
How It All Began
When the manufacturing of microfluid components first began it heavily relied upon the technology that was currently available. Different techniques from two-dimensional integrated circuits and silicon-based three-dimensional MEMS processes were used. This happens to include some fantastic technology such as film metallization, photolithography, and chemical etching.
It was until later on, that glass-based mixes of microfluidic fabrication techniques were starting to be used. This included mixtures of glass-silicon and glass-polymer. Glass mixtures were preferred for this process mainly because of the biocompatibility towards the related applications. Glass has the ideal surface characteristics of being a strong solvent and having a high temperature. The main issue was still the lack of optical transparency at the currently interesting wavelengths. It created a high expense to try and match up the characteristics of both silicon and glass.
It’s Been A Process
There had been a massive amount of effort to find alternative materials for the market to use that were far more cost-effective for both the manufacture and clients. With recent developments in technology polymer and plastic have gathered more interest than other solutions. Regardless of their weaker bonding structure, plastic materials have the advantage of being more economical and are easier to fabricate along with being easier to create interconnected material that works well together.
The reason of a stretch in interest for better material from both an academic and industry standpoint is the possibility of having easily disposable microfluidic chips for clinical and biomedical applications. For them to be disposable though they will definitely require a low fabrication cost as well as the ability for high volume production while being versatile enough for a broad spectrum of applications.
How Is It Currently Done?
Current fabrication methods for microfluidic devices include injection molding, hot embossing, and soft lithography. Direct manufacturing techniques such as laser machining, photolithography, and x-ray lithography are also used. Each one has its own sets of advantages and disadvantages to produce these materials. It is still unknown what ways are the most optimal for manufacturing as technology increases. For careers and training in microfluid components manufacturing, you should visit your online provider.
