Study on droplet microfluidic chips for drug screening against Candida albicans / 药学学报

ABSTRACT

A droplet microfluidic chip system was developed for drug screening against Candida albicans. The microfluidic chip was designed and prepared for the formation of droplets. Alamar blue was selected as an indicator for its characteristic of fluorescence mission in live cells. Four antifungal drugs (amphotericin B, caspofungin, 5-fluorocytosine, terbinafine) and a new drug (iodiconazole) were selected as model drugs to test the microfluidic chip approach. At the same time, 96-well microplate method was performed to verify the applicability of the chip method. The results showed that the developed droplet microfluidic chip platform was able to complete the antifungal susceptibility test within 2 h. In comparison with the 96-well microplate method, the microfluidic chip method showed a consistence of 100% with regard to the minimum inhibition concentrations and less reagent consumption. The new droplet microfluidic chip method is simple, rapid and suitable for rapid screening of antifungal drugs.
