Identification of Trace Polystyrene Nanoplastics Down to 50 nm by the Hyphenated Method of Filtration and Surface-Enhanced Raman Spectroscopy Based on Silver Nanowire Membranes

Qing Yang et al.

Summary: This study proposes a method that combines membrane filtration and surface-enhanced Raman spectroscopy to analyze trace nanoplastics in water. The method achieves high sensitivity detection of low-concentration nanoplastics by using a bifunctional Ag nanowire membrane to enrich and enhance their Raman spectra in situ.

Cross-Sectional Chemical Nanoimaging of Composite Polymer Nanoparticles by Infrared Nanospectroscopy

Monika Goikoetxea et al.

Summary: Nanoscale Fourier transform infrared spectroscopy (nano-FTIR) is a powerful technique for label-free chemical nanoimaging, which reveals unexpected composition of phases in complex polymer particles. The method allows for hyperspectral infrared nanoimaging and subsequent chemometric analysis, providing valuable insights beyond conventional electron microscopy analysis. This approach benefits the understanding of particle formation and the development of novel synthesis recipes and strategies.

Identification of polystyrene nanoplastics using surface enhanced Raman spectroscopy

Xiao-Xia Zhou et al.

Summary: The accumulation of micro- and nanoplastics in the environment is a major global issue, with concerns about potential harm to wildlife. Identification of nanoplastics in environmental samples remains a challenge, but surface enhanced Raman spectroscopy (SERS) has been shown as a feasible approach to quickly identify and analyze trace polystyrene (PS) nanoplastics. The proposed method has the potential to further study the occurrence, formation, and transports of nanoplastics in the natural environment.

Combining microcavity size selection with Raman microscopy for the characterization of Nanoplastics in complex matrices

Andrea Valsesia et al.

Summary: This study introduces a method for the extraction and Raman analysis of pNP in salt-water mussel tissues, combining enzymatic digestion/filtering to remove biological matrices with a detection/identification procedure using a micro-machined surface. The process involves the use of capillary forces to drive the self-assembly of suspended nanoparticles into cavities on the sensor surface, enabling size selective analysis of individual sub-micron pNP with confocal Raman microscopy.

Weathering Plastics as a Planetary Boundary Threat: Exposure, Fate, and Hazards

Hans Peter H. Arp et al.

Summary: The weathering of plastic pollution in the marine environment poses a threat to the planetary boundary with increasing exposure, poorly reversible pollution fate processes, and potential toxicological hazards exceeding thresholds in sensitive environments. Further research is needed to understand how increasing exposure and continuous weathering processes modulate toxicological hazards and to better parameterize the planetary boundary threshold for plastic pollution.

Correlative SEM-Raman microscopy to reveal nanoplastics in complex environments

Ruth Schmidt et al.

Summary: This study focuses on the analysis of NPs within the 100 nm range in challenging environments, using a correlative approach between scanning electron microscopy and Raman microscopy. Promising detection limits were found, with practical tests revealing limitations in reliable identification of unknown NPs. Combining this approach with advanced sample preparation techniques could yield a powerful tool for NPs analysis in various environments.

Identification and visualisation of microplastics / nanoplastics by Raman imaging (iii): algorithm to cross-check multi-images

Cheng Fang et al.

Summary: The study developed an algorithm to merge multiple Raman images in order to enhance mapping accuracy for the identification of microplastics/nanoplastics, with validation conducted on microplastics/nanoplastics potentially generated by laser printers in offices or homes. This approach improves the certainty of mapping and identification in complex samples containing various materials with overlapping Raman signals.
