Abstract

The presence of dispersed plastic particulates in the environment is an ecological problem of increasing relevance, posing in addition potential health risks as they enter the food chain. In the last years, increasing efforts are being spent to study and characterize the microplastics found in nature, particularly in aquatic environments. At the same time, there is a need to advance the instruments and techniques necessary to perform fast, quantitative, and reliable analysis of microplastics. In this framework, we present a compact and cost-effective holographic microscope, integrated with a commercial microfluidic chip to visualize and evaluate microplastic samples in flowing conditions. The preliminary results show that different microplastic samples can be clearly imaged in-flow through a Digital Holography microscope. This is the first step for assessing novel strategies for the detection and identification of microplastics.
