Nephelometric monitoring growth of Candida albicans using BMG LABTECH's NEPHELOstar Plus


Nephelometry measures the forward scattered light when passing solutions. This can be used to determine particles in solution as they increase light-scattering. The particles may be derived from drugs at their limit of solubility or from microbes. Hence, determination of drug-solubility and microbial growth are two main applications for nephelometry.


Using a microplate-based nephelometer, the NEPHELOstar® Plus, solubility of the antifungal substances Econazole-nitrate and ciclopirox-olamine each complexed with Cyclodextrins was monitored and showed a higher solubility than their uncomplexed form. The Cyclodextrin-complexes were studied regarding their antifungal activity on Candida albicans and revealed a higher efficiency of the Econazole complex as compared to the ciclopirox complex.
