  1. Moreover, the fluorophore attached to palmitic acid significantly increases cytotoxicity than dPA and photobleaching over time.

    How was cytotoxicity measured and compared to cells with dPA to ensure the Raman probes were not also cytotoxic?

  2. The first step was to prepare a calibration curve for RS. Deuterated fatty acid was dissolved in various concentrations of oleic acid and, after being applied to a CaF2 slide, spectra were measured for selected concentrations ranging from 0 mM to 3477 mM for dPA.

    These two sentences are repeated in this section.
