Impedance-Based Microfluidic Assay for Automated Antischistosomal Drug Screening

Area of Science:

• Biomedical Engineering
• Parasitology
• Drug Discovery

Background:

• Schistosomiasis affects 200 million globally, treated mainly by praziquantel.
• Drug resistance is a growing concern, necessitating new drug discovery.
• Current drug screening is manual, labor-intensive, and subjective.

Purpose of the Study:

• To develop an automated microfluidic platform for high-throughput antischistosomal drug screening.
• To utilize an impedance-based approach for objective assessment of parasite larvae viability.
• To enable multiplexed analysis for increased screening efficiency.

Main Methods:

• A microfluidic platform with integrated electrodes was designed.
• The platform uses impedance to detect parasite larvae size and motility.
• Schistosoma mansoni larvae were exposed to varying concentrations of mefloquine.

Main Results:

• The platform successfully recorded size and motility variations of Schistosoma mansoni larvae.
• Motility served as an unbiased estimator for larvae viability.
• The system demonstrated potential for high-throughput analysis.

Conclusions:

• The developed microfluidic platform offers an automated and efficient method for antischistosomal drug screening.
• This technology can accelerate the discovery of novel drugs to combat schistosomiasis.
• The impedance-based approach provides objective and reliable viability assessment.
