Nano- and microplastic particles are a global emerging environmental issue that might pose potential threats to human health. The present work exploits artificial intelligence (AI) identify nano- microplastics in water by monitoring the interaction of sample with sensitive surface. An estrogen receptor (ER) grafted onto gold surface, realized on nonexpensive easy-to-produce plastic optical fiber (POF) platform order excite surface plasmon resonance (SPR) phenomenon, has been developed carry out "smart" interface (ER-SPR-POF interface). ER-SPR-POF offers output data useful for exploiting machine learning-based approach achieve particle sensors. This proof-of-concept sensor through training phase carried different particles, terms materials size. experimental results have demonstrated proposed combined AI can be used kind (polystyrene; poly(methyl methacrylate)) size (20 μm; 100 nm) an accuracy 90.3%.

Micro- and nano-plastics (MNPLs) can move along the food chain to higher-level organisms including humans. Three significant routes for MNPLs have been reported: ingestion, inhalation, dermal contact. Accumulating evidence supports intestinal toxicity of ingested their role as drivers increased incidence colorectal cancer (CRC) in high-risk populations such inflammatory bowel disease (IBD) patients. However, mechanisms are largely unknown. In this review, by using leading scientific publication databases (Web Science, Google Scholar, Scopus, PubMed, ScienceDirect), we explored possible effects related MNPL exposure on gut epithelium healthy conditions IBD The summarized idea that oral may contribute epithelial damage, thus promoting sustaining chronic development inflammation, mainly Colonic mucus layer disruption further facilitate passage into bloodstream, contributing toxic different organ systems platelet activation, which may, turn, inflammation CRC development.

While microplastics and nanoplastics are emerging as a big environmental concern, their characterization is still challenge, particularly for identification simultaneous quantification analysis where imaging via hyper spectrum generally needed. In the past few years, Raman has been greatly advanced, but protocol complicated not yet standardized because different from traditional analysis. Herein we provide step-by-step demonstration of how to employ confocal techniques image nanoplastics.

Paper cups have been widely used such as in the fast-food industry for drinking and are generally made of disposable material. To make paper cup waterproof prevent leakage, a thin layer plastic polylactic acid (PLA) is commonly coated onto inner wall surface. This can potentially release debris microplastics, particularly when wrinkled/crumpled to break peel off coating layer, which tested herein. Using scanning electron microscope (SEM), broken be clearly observed. We then identify material using mass Raman spectra. further employ imaging released fallen down microplastics. cross-check image with SEM benefit each other increase analysis certainty, because via hyper spectrum signal-to-noise ratio, while visualise high resolution micro-/nano- size. particle algorithm estimate amount, at approximate 180 microplastic/wrinkle, or micro-bioplastic if considering main PLA bioplastic.

Polymer science, a discipline focusing on the synthesis, characterization, and application of macromolecules, has increasingly benefited from adoption machine learning (ML) techniques. Among these, Support Vector Machines (SVMs) stand out for their ability to handle nonlinear relationships high-dimensional datasets, which are common in polymer research. This review explores diverse applications SVM science. Key examples include prediction mechanical thermal properties, optimization polymerization processes, modeling degradation mechanisms. The advantages contrasted with its challenges, including computational cost, data dependency, need hyperparameter tuning. Future opportunities, such as development polymer-specific kernels integration real-time manufacturing systems, also discussed.
