Abstract

Microalgae are increasingly recognized for their nutritional value and sustainable production potential. However, growing microalgae in wastewater poses risks due to pollutants like pathogens and nanoparticles. Optical coherence tomography (OCT) offers real-time, high-resolution imaging to visualize and quantify algae-nanoparticle interactions. This study used OCT to capture three-dimensional volumes of microalgae under three conditions: interaction with quantum dots (qdots), exposure to buffer, and a control group. Statistical tests on attenuation coefficients revealed significant differences in algae exposed to qdots. These results demonstrate OCT's potential for monitoring algae-pollutant interactions, with future work focused on further quantification and advanced machine learning tool.
