In recent years, microplastics have been detected in various environments, including seawater, soil, food, and even human bodies. Understanding the health and environmental impacts of microplastics is a growing concern. This perspective highlights the importance of developing methods to separate and quantify exposure to the smallest microplastics, as traditional methods unintentionally exclude them. Electrokinetic methods are suggested as a potential solution and the key research directions for advancing this technology are discussed.
In recent years, microplastics have been found in seawater, soil, food, and even human blood and tissues. The ubiquity of microplastics is alarming, but the health and environmental impacts of microplastics are just beginning to be understood. Accordingly, sampling, separating, and quantifying exposure to microplastics to devise a total risk assessment is the focus of ongoing research. Unfortunately, traditional separation methods (i.e., size- and density-based methods) unintentionally exclude the smallest microplastics (<10 mu m). Limited data about the smallest microplastics is problematic because they are likely the most pervasive and have distinct properties from their larger plastic counterparts. To that end, in this Perspective, we discuss using electrokinetic methods for separating the smallest microplastics. Specifically, we describe three methods for forming electric field gradients, discuss key results within the field for continuously separating microplastics, and lastly discuss research avenues which we deem critical for advancing electrokinetic separation platforms for targeting the smallest microplastics.
