Home Topics Bioprocessing Microfluidic Diffusional Sizing: A Novel Method for Characterizing Protein Interactions Microfluidic lab-on-a-chip devices guide tiny fluid volumes through one or several analytical paths on a single integrated circuit, emulating the sort of miniaturization seen in microelectronic devices. It should come as no surprise, then, that lab-on-a-chip fabricators borrow technologies, such as photolithography, from the semiconductor industry. Other borrowings (from other industries) include injection molding and liquid digital dispensing technology.
