Nanoplastics, emerging as pervasive environmental pollutants, pose significant threats to ecosystems and human health due their small size potential toxicity. However, detecting trace levels of nanoplastics remains challenging because limitations in the current analytical methods. Herein, we propose a method that combines superhydrophobic enrichment with SERS analysis for aqueous environments. Superhydrophobic substrates were prepared by using liquid-liquid self-assembly method. The superhydrophobicity facilitated analyte enrichment, monolayer Au nanoparticles (AuNPs) enhanced Raman signals. detection limit probe crystal violet (CV) this substrate reached nanomolar (10-9 M), an RSD 9.96% across 40 × μm2 area (441 spots), demonstrating excellent sensitivity reproducibility.

Plastic pollution, particularly from microplastics (MPs) and nanoplastics (NPs), has become a critical environmental health concern due to their widespread distribution, persistence, potential toxicity. MPs NPs originate primary sources, such as cosmetic microspheres or synthetic fibers, secondary fragmentation of larger plastics through degradation. These particles, typically less than 5 mm, are found globally, deep seabeds human tissues, known adsorb release harmful pollutants, exacerbating ecological risks. Effective detection quantification essential for understanding mitigating impacts. Current analytical methods include physical chemical techniques. Physical methods, optical electron microscopy, provide morphological details but often lack specificity time-intensive. Chemical analyses, Fourier transform infrared (FTIR) Raman spectroscopy, offer molecular face challenges with smaller particle sizes complex matrices. Thermal including pyrolysis gas chromatography–mass spectrometry (Py-GC-MS), compositional insights destructive limited in analysis. Emerging (bio)sensing technologies show promise addressing these challenges. Electrochemical biosensors cost-effective, portable, sensitive platforms, leveraging principles voltammetry impedance detect adsorbed pollutants.

In the past decade, microplastics (MPs) have drawn significant attention as widespread environmental contaminants, with research increasingly highlighting their harmful effects on respiratory health in aquatic and terrestrial organisms. Findings revealed human lung tissues, raising concerns about potential role damaging tissue integrity contributing to pulmonary fibrosis-a chronic inflammatory condition characterized by scarring of epithelial tissues due accumulated extracellular matrix, triggered factors such alcohol, pathogens, genetic mutations, pollutants. this review, we explore both well-studied lesser-studied mechanisms signaling pathways, aiming shed light how might act mediators that activate distinct, often overlooked cascades. This review searched PubMed Google Scholar using keywords like "plastic," "microplastic," "lung fibrosis," "pulmonary system," "exposure route," "signaling pathways," combined "OR" "AND" singular plural forms. These pathways could not only induce damage but also play a development fibrosis. be targeted reduce microplastic-induced fibrosis, opening new avenues for future treatments.
