Preprint on FRET analysis is now live!
Happy to be part of the kinSoftChallenge - a blind study of single-molecule fluorescence resonance energy transfer (smFRET) kinetic analysis algorithms. Observing the movements of one single molecule over time provides information of the underlying energetic origin of protein function at the (sub-)molecular level. Yet, experimental & fundamental limitations complicate the extraction of this important information. The challenge compared different kinetic softwares to determine what the strengths and weaknesses of each were for analyzing data complicated by noise, multiple states, or degeneracies. The results of this multi-team study are now available via BioRxiv and are under peer review. Check out the results here! https://doi.org/10.1101/2021.11.23.469671

Congrats to the grads, Shawn and Andrew!
It was a celebratory but also somewhat sad day in lab, as we sent off seniors Shawn (Physics, 2021) and Andrew (Engineering Physics, 2021). They accomplished a lot during their time in the group. Shawn was the OG member since 2019 and worked on the fcsSOFI project, publishing our first analysis paper in Optics Express and code available on GitHub. He mastered the art of presenting on Zoom throughout the past year. Andrew was a jack of all trades on a project that required engineering and interdisciplinary work. He used ThinkBox laser cutters and 3D printers to build a gel stretcher and learned some polymer chemistry with hydrogel synthesis. He took a project that was an idea on paper and made it a reality! We wish them the best as they pursue their PhDs at Caltech & UIUC, respectively!

Optics Express publication on GPU-parallelized fcsSOFI
Congrats to Shawn, Will, Nam, and Bill on their publication and software package! fcsSOFI is our correlation-based analysis code that allows for super-resolution imaging of diffusion dynamics. We’ve improved the computation time by 40x and expanded the diffusion models to image anomalous diffusion in biophysically-relevant environments. We hope that the user-friendly GUI will allow other researchers to apply our analysis to their own research.
You can check out the paper here: https://doi.org/10.1364/OE.416465
Lydia nominated for the J. Bruce Jackson, M.D., Award for Excellence in Undergraduate Mentoring!
Happy Holidays - our first research article on corrosion detection is now live!
Find it here: https://pubs.acs.org/doi/10.1021/acsami.0c18994
Congrats to Anuj and Hannah! We show that corrosion can be monitored with dyes that can be detected at the single molecule scale. We first characterized the dye turn-on of Fe corrosion in bulk, resolving color & fluorescence changes, along with quantifying kinetics. Then we moved onto the microscopic detection showing we can observe single molecule corrosion events with our fluorophore readout on our TIRF microscope. Previous fluorescence corrosion detection was therefore only limited by the optical components used.
This work is the first step in what we hope is a new way to understand corrosion at the ultimate limit of detection. We have more work in the pipeline on the diffusion of our dye & are looking forward to studying the spatial & kinetic dynamics of corrosion at the single-molecule level.
Kisley Group sweeps the Intersections conference physical science awards!

Perspective published in Analytical Chemistry
Congrats to Bill on his first publication “Transforming separation science with single-molecule methods.” Written in collaboration with the Landes group at Rice, we present our perspective on future ways single molecule microscopy can contribute to our understanding of separations. We discuss ways that instrumentation improvements (multicolor, 3D imaging, time resolution), sample complexity (mixtures, high concentrations, solvents), & expanding the types of separations studied at the single molecule level (chiral, radiochem, etc.) can be applied in new ways.
Publication in Langmuir
Check out our collaborative paper with Ryan Bailey’s group at Michigan and Paul Braun’s group at Illinois showing how different polymer brush-analyte properties can be quantified with a single tool: the microring resonator. pKa, partition coefficients, diffusion constants, brush thickness, and analyte penetration depth can all be determined.
