The spectra for Synechococcus sp. WH8102 (orange) was collected on March 13, 2014 and the spectra for Prochlorococcus marinus MED4 (green) was collected on March 18, 2014. Both cultures were grown at 260 μmol photons m-2 s-1 and tested in late exponential growth phase using the Olis CLARiTY 17 photometer (Bogart, Georgia). Spectra were corrected as described in Materials and Methods, section 3.5, and normalized to a value of 1.00 at their red peaks.

Monitoring Vitamin A delivery & uptake in a suspension of photoreceptor cells
November, 2013
Day 1 proof of concept experiment, results substantiated by Nobel Prize winner George Wald’s 1955 seminal paper on visual pigments & Vitamin A uptake. Precise kinetic measurements on Day 2 will be used in a publication to follow.
Samples and photograph of were provided by Dr. Gonzalez-Fernandez, experiments conducted by Drs. Richard DeSa & Federico Gonzalez-Fernandez at the OLIS facility.

Exciting new data from the Hartsel Lab: Amphotericin B with a liposomal drug delivery system
July, 2013
“Just thought I would send some of our early spectra from Gary’s OLIS CLARiTY system (http://www.olisclarity.com/). As promised, the integrated cavity cells rendered extreme light scattering nearly nonexistent . Here are some spectra from a putative orally available drug delivery emulsion of Amphotericin B (developed by K. Wasan and colleagues at UBC). Quite remarkable that we could pull these spectra out of this milky emulsion (see photos). When the commercial liposomal drug, Abelcet was added it is clear that the drug delivery system began to “dismantle” the lipid particles into drug monomers. This is something we could not have seen any other way. . . . Some spectra taken with a conventional Cary-50 are included to provide a contrast–and what a contrast! I can see where this system could have lots of pharmaceutical applications. :-)”

Phytoplankton data from the Campbell Lab
May, 2013
“We are accumulating data on several fronts using the CLARiTY. Here is a quick slide I did for a group meeting, showing what the CLARiTY can do for dilute phytoplankton suspensions (in this case, a culture of Prochlorococcus).”

Maple Seed Pods from Dr. DeSa’s front yard
April, 2013
Leaving for work one Friday morning, Dr. DeSa’s wife handed him these pretty maple seed pods that she picked up from their porch and laughingly suggested he pop them into the CLARiTY for analysis. This little experiment suggests the countless free, safe, and available samples one might examine in a teaching laboratory.
