Cell phone digital microscopy using an oil droplet
They introduce an accessible cell phone imaging method using small droplets of microscope immersion oil and consumer-grade oils. Oil droplets were more resistant to
evaporation than water droplets. The droplets were optically characterized using a cell phone screen and resolution target.https://opg.optica.org/boe/fulltext.cfm?uri=boe-11-5-2328&id=429699
