Atmospheric ice-nucleating particles (INPs) make up a vanishingly small proportion of atmospheric aerosol but are key to triggering the freezing supercooled liquid water droplets, altering lifetime and radiative properties clouds having substantial impact on weather climate. However, INPs notoriously difficult model due lack information their global sources, sinks, concentrations, activity, necessitating development new instrumentation for quantifying characterizing in rapid automated manner. Microfluidic technology has been increasingly adopted by ice nucleation research groups recent years as means performing droplet analysis INPs, enabling measurement hundreds or thousands droplets per experiment at temperatures down homogeneous water. The potential microfluidics extends far beyond this, with an entire toolbox bioanalytical separation detection techniques developed over 30 medical applications. Such methods could easily be adapted biological biogenic INP revolutionize field, example, identification quantification bacteria fungi. Combined miniaturized sampling techniques, we can envisage deployment microfluidic sample-to-answer platforms automated, user-friendly field that would enable greater understanding seasonal activity. Here, review various components such platform incorporate highlight feasibility, challenges, endeavor, from assays separations bioanalysis.
