Technical Note: EcoExposure Platform for Multi-Matrix Detection in Intact Liquid Media Across Industries and Fields

The EcoExposure Platform, developed by ecotera asia, represents a unified, field-deployable system for direct detection of microplastics and nanoplastics in intact liquid samples without destructive preparation or complex lab workflows. Built around a standardized smartphone-based workflow involving controlled dilution, an optically interactive reagent, and adaptive time-resolved optical metrics, the platform evaluates macroscopic interaction behavior in the full liquid matrix rather than isolating individual particles. While initially demonstrated in environmental water and select biological fluids, its core architecture is being actively expanded into non-biological, consumer-product beverages and complex liquids such as milk, juice, infant formula, beverage extracts, and colloidal food systems, leveraging matrix-specific calibration through dilution and software rather than redesigning the assay.This enables rapid, scalable screening across diverse colors, ionic strengths, and optical densities, positioning the technology for widespread consumer at-home testing of everyday drinks, as well as industrial quality control, batch monitoring, and supply chain applications in the beverage sector. Water serves as the foundational matrix, but the platform’s unified design marks it as the entry point for a broader multi-matrix exposure intelligence solution tailored to accessible, real-world beverage safety and exposure monitoring.
