Multi-Matrix Approach:
Water, Urine, and Blood and Beyond
One platform, multiple sample types:
A unified framework for detecting microplastics and nanoplastics across environmental (including milk, juice other food/beverage) and biological matrices rather than treating each sample type as a separate problem.
Status:
- Urine Diagnostic Development with US FDA Regulatory filings and human samples

Key Points:
-
Water as the foundation: Freshwater and saltwater provide lower-background systems that are useful for initial method development, calibration, and real-world environmental monitoring.
-
Extension to urine: Urine introduces moderate biochemical complexity (salts, urea, proteins, debris), creating an important bridge between environmental testing and human exposure monitoring.
-
Future blood applications: Blood is a highly complex matrix with cells, proteins, lipids, and strong optical interference, but it may enable deeper understanding of systemic exposure and disease relationships.
-
Shared analytical principles: Core detection concepts—optical signals, particle interactions, aggregate patterns, and matrix-aware interpretation—can be adapted across sample types.
-
From environment to health: Integrating water and human testing may help connect environmental contamination with measurable biological exposure.
-
Scalable monitoring vision: A multi-matrix strategy supports future decentralized testing, longitudinal data collection, and broader public health intelligence.
-
Why it matters: Most existing methods are optimized for a single matrix. A cross-matrix approach aims for greater consistency, comparability, and real-world usability.
