EcoExposure™ Part II: Smartphone Polymer Typing for Scalable Plastic Monitoring
AI summary Read the abstract
Researchers describe a smartphone-compatible polymer-typing module designed as the second tier of the EcoExposure monitoring platform, arguing that total-burden screening and polymer-specific classification are sequential rather than competing approaches and together form a complete field-deployable microplastic monitoring system.
Microplastic and nanoplastic (MP/NP) monitoring is often framed as a choice between total burden measurement and polymer-specific identification. In practice, both functions are valuable and complementary. This perspective outlines Part II of a dual-path monitoring framework that has long been part of the EcoExposure™ platform roadmap: a portable smartphone-enabled pathway for polymer-specific classification. Part I focuses on scalable total burden measurement for broad screening, exposure tracking, and decentralized monitoring. Part II will aim to add higher-resolution insight regarding likely plastic types in field and consumer settings. The central argument is that burden-first and typing-second are not competing strategies; they are sequential and synergistic layers of a complete monitoring ecosystem.

EcoExposure™ Part II: Smartphone Polymer Typing for Scalable Plastic Monitoring
AI summary Read the abstract

EcoExposure™ Water Platform: Field-Deployable Total Plastic Burden and Plastic-Type Assessment A Dual-Path Framework for Scalable Microplastic and Nanoplastic Water Monitoring
AI summary Read the abstract
Researchers are developing a portable, smartphone-based tool that can quickly measure how much plastic (both microscopic pieces and even tinier "nanoplastic" bits) is in a water sample, without needing a lab. This matters because right now, tracking plastic pollution in our water supplies is slow and expensive, an easier field tool could help identify contaminated areas faster and check whether water filters or cleanup efforts are actually working. Note that this describes a monitoring technology still in development, not a study on health effects of microplastics themselves.
Designing Field-Deployable, AI Smartphone-Based Diagnostics for Global Scalable Water Intelligence: The EcoExposure Platform
AI summary Read the abstract
Researchers describe the EcoExposure platform, a smartphone-native water quality testing system designed around real-world field constraints rather than miniaturized lab instruments, with microplastics and nanoplastics as the flagship analyte and extensibility planned for PFAS, heavy metals, and other contaminants.
EcoExposure™ for Scalable Geospatial Monitoring of Microplastics and Nanoplastics in Marine Ecosystems: Enabling Frequent Monitoring, Hotspot Identification, and Intervention Evaluation
AI summary Read the abstract
Scientists have developed a smartphone-based tool called EcoExposure™ that can quickly screen ocean, coastal, and fish-farming waters for tiny plastic particles (microplastics and nanoplastics) without needing expensive lab equipment. This matters because these plastics can work their way up the food chain into the seafood we eat, and having a cheaper, faster way to spot contamination "hotspots" could help catch problems earlier and track whether cleanup efforts are actually working. Note that this paper is a review discussing the tool's design and potential rather than presenting new contamination data itself.
Smartphone-enabled rapid quantification of microplastics
AI summary Read the abstract
A smartphone-based system was developed to rapidly quantify microplastics from environmental samples, reducing analysis time from hours or days to a much faster workflow without requiring expensive lab equipment. The method was validated against standard techniques and shown to be suitable for field-deployable microplastic monitoring.
