Paper Abstract

Recent advances in inkjet-printed optics have created a new class of lens fabrication technique. Dubbed DotLens, a single of which weighs less than 50 mg and occupies a volume less than 50 μL. DotLens can be attached onto any smartphone camera akin to a contact lens, and turn the smartphones into a microscope. In this paper, we show recent results from images collected from a variety of biological samples. Lately, we have demonstrated that by data analytics the smartphone microscope is capable of detect nanoscale objects and their minute color changes, called nanocolorimetry. We have applied it to the detection and quantification of lean ion in drinking water with performance surpassing the EPA standard.
