Fig. 5From: Buckyballs conjugated with nucleic acid sequences identifies microorganisms in live cell assaysA mixed culture of labeled B. subtilis and S. sanguinis can be sorted, by their preferred chemoattractants placed in the sink wells of a microfluidic system. a B. subtilis and S.sanguinis were labeled with their corresponding probe complexes and placed in the well called the “original microbial pool.” b the original microbial pool, and Fe and glucose chemoattractants were placed in source and sink wells, respectively. c B. subtilis migrated toward Fe2+ rich sink-well while, d S. sanguinis migrated to the glucose rich sink-well. The source and sink wells are monitored by fluorescent microscopyBack to article page
