Mobile dark-field microscope image analysis for biomolecule quantification is feasible upon mating an LED light source, a dark-field condenser and a 20× objective lens to a mobile phone camera. This system can achieve performance analogous to that of a standard dark-field microscope, allowing the use of stable, nanoparticle-based quantitation assays in resource-limited areas where standard assay approaches are not practical.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
