Hybridizations of two C60-RNA-DNA-reporter complexes with their corresponding bacteria, B. subtilis and S. sanguinis, are monitored by super-resolution microscopy. The reporters for B. subtilis and S. sanguinis are excited at 568 and 488 nm, respectively. a-c are B. subtilis incubated with B. subtilis probe complex. a shows no fluorescent signal when excited at 488 nm, b is the fluorescent signal at the 568 nm excitation frequency. d-f are S. sanguinis, incubated with S. sanguinis probe complex, d is fluoresces at the 488 nm excitation frequency, and e shows no fluorescence signal at the 568 nm excitation frequency. g-i are mixed bacteria treated with mixed probe complexes to indicate that each bacterium can be visualized at its corresponding excitation frequency
