A Silicon Nanomembrane Analysis Pipeline (SNAP) for Multimodal Analysis of Microplastics in Drinking Water
AI summary Read the abstract
Researchers developed the Silicon Nanomembrane Analysis Pipeline (SNAP)—a workflow using silicon nitride nanomembranes to capture, concentrate, and multimodally characterize microplastics in drinking water. Applied to Rochester, NY water samples, SNAP enabled individuated particle identification by optical and electron microscopy and Raman spectroscopy on the same substrate, demonstrating a streamlined approach for routine drinking water MP analysis.
The biological impact of microplastics in human food and water sources is largely unknown, and drinking water sources are not exempt from microplastic contamination. Here, we demonstrate a streamlined approach for capturing, quantifying, and identifying microplastics in drinking water. We present an analytical workflow termed Silicon Nanomembrane Analysis Pipeline (SNAP) that takes advantage of novel silicon nitride nanomembranes which enable a significant “concentration factor," consolidating suspended particles into a planarized observation area for individuated, quantifiable, and multimodal particle analysis on the same substrate. Drinking water samples sourced in the Rochester, NY region were collected and analyzed using SNAP. Particles in each sample were characterized by optical and electron microscopy, Raman spectroscopy, and various identified constituents were quantified in proportion to total captured particles.

Silicon Nanomembrane Filtration and Imaging for the Evaluation of Microplastic Entrainment along a Municipal Water Delivery Route
AI summary Read the abstract
This study filtered municipal drinking water samples from multiple points along Rochester's water delivery system and found microplastics at every stage including post-treatment. The findings confirm that conventional water treatment does not fully remove microplastics, meaning tap water is a potential route of human exposure.

Tracking nanoplastics in drinking water: a new frontier with the combination of dielectrophoresis and Raman spectroscopy
AI summary Read the abstract
Researchers developed a new combined technique using dielectrophoresis and Raman spectroscopy to detect and identify nanoplastics in drinking water. The method can trap and concentrate nanoplastic particles that are too small for conventional detection approaches, then chemically identify them. This advancement addresses a critical gap in our ability to monitor nanoscale plastic contamination in water supplies.
