Example Applications for a CLARiTY UV/Vis

What would yours be?

  • Broadband growth / concentration monitoring of intact cells for accurate biomass quantitation even with scattering; seeing how the pigment profile changes during growth to track physiological state, not just concentration; real-time, non-destructive monitoring from fermenters, photobioreactors, cell factories; and much more!

  • Pigment quantitation in intact cells (chlorophyll, carotenoids, heme) to capture specific absorbance peaks at precise wavelengths (e.g., his algal culture has 12 µg/mL chlorophyll a and 3 µg/mL carotenoids; the heme content of this bacterial suspension doubles during stationary phase; etc.

  • Aggregation kinetics of nanoparticles or formulations (is the drug nanoparticle formulation stable or prone to clumping), useful while adjusting stabilizers or surfactants to reduce aggregation; provides a quantitative measure of shelf-life or batch consistency.

  • Drug loading & release in nanoparticle formulations (in situ), i.e., how quickly the drug is taken up by the nanoparticles during loading, or how fast it is released into the surrounding medium; the loading efficiency (% of drug actually loaded into nanoparticles); measure in the natural state of the formulation, avoiding artifacts caused by sample manipulation; and much more!

  • Kinetics of cell lysis or membrane permeabilization, i.e., monitor cell viability during protein production in bioreactors to maximize yields; evaluate how nanoparticles, peptides, or drugs affect cell membranes; screen compounds for cytotoxicity quickly and quantitatively.

  • Protein corona formation and binding on nanoparticles (spectral shift & scattering changes), i.e., rate of corona formation, saturation point (maximum protein coverage), stability of the corona over time, etc.

  • Enzyme assays with particulate substrates, i.e., design better enzymes, formulations, and reaction conditions; multiple enzyme-substrate combinations can be monitored without tedious sample prep; real-time monitoring of biocatalytic processes (biofuels, food processing, detergents) improves efficiency and quality control.
