Abstract

We introduce a cost-effective imaging method using droplets of consumer-grade cooking oil and a cell phone camera. While cooking oil droplets are not specifically designed for imaging, we found that, similar to immersion oil, they were more resistant to evaporation than water, thereby enabling long-term imaging. We harnessed their close refractive index to immersion oil and demonstrated their use as lenses for cell phone microscopy. Our new method enables stable droplet-based optical imaging primarily using household materials without specialized setups or manufacturing processes.
