Week #6 Update

This week’s research mainly consisted of continuing to take more data of EY on TiO2 under both oxic (air) and anoxic (N2) environments. We have been continually taking blinking trace data of these single molecules. By continually building a larger data set, we can then move towards running the data set through clauset analysis. This allows us to see how well distributions of ON segments and OFF segments of our blinking data fit to certain distributions. These distributions will give us insight into the underlying kinetics of EY. We have continued to parse out the contaminated data and also considering whether certain molecules on the border of ‘good’ and ‘bad’ should be included or not. Additionally, after compiling multiple workups of our scans and corresponding blinking traces, we have a more concrete idea of how EY on TiO2 should qualitatively look like, in air and N2 compared to EY on glass.

I also want to mention that we have recently tried our setup with a drop of water within our flow cell that houses the sample. This was done in order to see whether we could actually take scans under our confocal microscope with our sample under an aqueous environment. We were able to obtain scans as well as blinking traces, meaning there is potential in future projects that looks at our sample under aqueous conditions.
