Microfluidics: The Challenge Is to Bridge the Gap Instead of Looking for a ‘Killer App’

Currently, lab-on-a-chip solutions exist for a myriad of highly useful biological applications, including but not limited to single-cell mRNA sequencing, protein crystallization, real-time tracking of neuronal protein in isolated axons, antibody-secreting B cell screening, lymphocyte counters for point-of-care HIV diagnostics, and in vitro transcription and translation analysis. [...]they remain exotic pieces of academic laboratory exploration.
