Microscale systems can be devised to conduct accurate point-of-care analysis by integrating operations to manipulate tiny amounts of fluids for faster and precise biochemical assays, eliminating much cumbersome instrumentation and shrinking the assay timescales. The system engages micro-channels, sensors, and valves to automate the amalgamation of samples for processing and their detection, eliminating the need for bulky gadgets. The devices function by applying capillary forces and electro-kinetics to conduct these biochemical tests accurately and quickly on minute volumes of samples. Their ability to be easily transported and the ease of use make them a good fit for decentralized diagnostic tests in places where healthcare provision is anchored, ensuring quick clinical decisions and bespoke patient treatment plans. Innovations emerging in the materials used, the methods of device creation, and the capability to run multiple tests at once enrich their efficiency and accuracy greatly. By operating to downsize the sample's scale and engage precise monitoring as it flows, microfluidic devices aim to be a significant player in providing timely and accurate diagnostics.

The easier, faster prototyping technology remains PDMS or alternatives like flexdym. Here is a researcher's interview on thermoplastic chips if you are interested :
