The accumulation of micro- and nanoplastics (MNPs) in the environment increasingly entails human exposure to this class of highly diverse polymer particles. To evaluate potential risks to human health, hazard assessments commonly involve in vitro testing using human-derived cell lines to establish dose-response relationships for MNPs. However, the reliable quantification of actual particle uptake in cells is particularly challenging for nanoscale materials (particles less than 1 μm in size). We…

Nanoplastics (NPs) are ubiquitous environmental contaminants, yet their subcellular fate from membrane encounter to destination remains poorly understood due to limitations in imaging resolution. Here, we address this gap by using stimulated emission depletion (STED) super-resolution microscopy to visualize the complete intracellular journey of individual NPs at nanoscale precision. A photostable AIEgen-core NP enabled resolution of individual NPs and real-time tracking of their nanoscale…

Raman spectroscopy is a commonly used label-free technique for the chemical analysis of microplastics (MPs), which are defined as plastic particles larger than 1 μm but smaller than 5 mm size; given its small signal strength and diffraction-limited spatial resolution, Raman spectroscopy has limited applicability in the study of nanoplastics (NPs), which are defined as particles smaller than 1 μm. Tip-enhanced Raman scattering (TERS) is a promising technique that can overcome these limitations by…

Acrylamide, bisphenols, phthalates, and micro- and nanoplastics are pervasive environmental pollutants with well-documented carcinogenic, neurotoxic, and reproductive effects. Nonetheless, their potential contribution to cardiovascular diseases remains strikingly unrecognised, despite the rising incidence of their clinical manifestations in younger populations and growing evidence of their effects on haemostasis and thrombosis. Single- and dual-antiplatelet therapy only partially controls the…

This systematic literature review (B-SLR) examines the emerging scholarly consensus on mechanistic linkage between genotoxic exposures and multisystem health dysfunctions. We systematically reviewed 200 peer-reviewed publications from 2021 to 2025 applying SPAR4-SLR protocol with quality appraisal using ROBINS-I adaptation and also performed assessment of publication bias. We have identified trends in genotoxicity research and its causal relationship with reproductive and neurocognitive health…

Microplastic (MP) pollution in tropical mangroves is an emerging environmental concern, yet the mechanisms governing particle retention, remobilization, and ecological exposure remain poorly understood. This critical review synthesizes current evidence from the Can Gio Mangrove Biosphere Reserve (Vietnam) using a three-tiered evidence hierarchy to distinguish local observations, contextual evidence, and testable hypotheses. Existing studies reveal severe methodological fragmentation, including…

The fragmentation and direct release of plastic debris have emerged as a pressing ecological concern. Once dispersed, these particles infiltrate food webs, accumulate within organisms, and bind toxic co-contaminants, posing long-term risks to ecosystems and human health. Despite growing awareness, the characterization of nanoplastics remains highly challenging. Moreover, obtaining additional information, such as particle shape or material composition, further exacerbates these detection hurdles….

Nanoplastics (< 1 μm) represent a pervasive class of environmental contaminants with unique physicochemical properties that profoundly influence microbial ecosystems. Their high surface-area-to-volume ratio, weathering-induced functionalization, and ability to adsorb chemical pollutants and biomolecules facilitate intricate interactions with bacterial communities. This review systematically examines nanoplastic-bacteria interactions, highlighting mechanisms such as oxidative stress induction,…

Micro- and nanoplastics (MNPs) are widespread environmental pollutants of growing concern due to their persistence and impacts on ecosystems and human health. Their small size, chemical complexity, and low environmental concentrations make accurate detection and quantification challenging. Single-particle (sp) ICP-MS has emerged as a promising technique for sizing and quantifying small MNPs based on their elemental content, yet the performance of different ICP-MS instrument types remains…

The wide use of plastic materials leads to increased emissions of micro-nanoplastics (MNPs) into the environment, raising significant concerns about their impact on human health. Traditional experimental approaches for assessing MNPs toxicity are costly, time-consuming, and there are no experimental protocols that are universally acceptable. Computational modeling using machine learning (ML) approaches provides an efficient alternative to MNP toxicity assessment. However, most modeling studies…
