Blog Post Image: UCLA engineers first to detect and measure individual DNA molecules using smartphone microscope

Smartphone microscope. (a) Photographs of the mobile-phone based fluorescence microscopy platform for single DNA molecule imaging and sizing. A Windows-based smart application running on the same mobile-phone was also created to transfer images from the phone to a custom-designed remote server and display the received DNA analysis results back on the screen of the phone. (b) A 3-D illustration of the same opto-mechanical attachment. (c) Schematic illustration of a simple DNA stretching method used in this work. (d) Representative fluorescence microscope images of stretched DNA molecules that are acquired by using the mobile-phone microscope (left) and a bench-top fluorescence microscope with a 100× oil-immersion objective lens, NA=1.3 (right). Scale bar, 10 microns. Image credit: Ozcan Lab at UCLA (Click image to enlarge)
