ClearMorphological and chemical characterization of nanoplastics in human tissue
Researchers developed methods to visualize and chemically characterize nanoplastics that have accumulated in human tissue samples. They were able to identify plastic particles smaller than one micrometer within tissue using advanced microscopy and spectroscopy techniques. The study provides some of the first direct evidence of nanoscale plastic accumulation in the human body, which is essential for designing future health effects research.
Detection of nano- and microplastics in mammalian tissue
This review examined methods for detecting nano- and microplastics in mammalian tissue, surveying analytical approaches as concerns grow about accumulation in biological systems. The paper discussed how continuous fragmentation and environmental accumulation are increasing the likelihood of tissue uptake across multiple organ systems.
Methods for the detection of microplastics in mammals
Scientists now detect microplastics in human blood, lungs, placentas, and other tissues, but the field still lacks a single gold-standard method for measuring them. This review compares the strengths and limitations of current detection techniques — including spectroscopy, microscopy, and chemical digestion — to help standardize how microplastics in the human body are quantified, which is a prerequisite for accurately assessing health risks.
Identifying Microplastic Contamination in Marine Biota
This study developed and evaluated methods for identifying microplastic contamination in marine biota, comparing visual sorting, spectroscopic, and chemical digestion approaches for extracting and confirming plastic particles from tissue samples.
Detekce mikroplastů v životním prostředí
This Czech bachelor's thesis provides an overview of microplastics as environmental pollutants, covering their sources, detection methods, and potential health risks for humans and other organisms. It notes that research in the past decade has confirmed that long-term microplastic exposure causes increasingly serious biological effects.
Mikroplastika U Slatkim Vodama: Pregled Načina Uzorkovanja I Pratećih Analiza
This review summarizes methods for sampling and analyzing microplastics in freshwater environments, covering filtration, visual sorting, and spectroscopic identification techniques. Standardizing sampling methods is critical because microplastics are persistent pollutants that can take thousands of years to decompose and negatively affect aquatic organisms.
Investigation of Detection Method for Nanoplastics in Shellfish
Researchers investigated detection methods for nanoplastics in shellfish, evaluating analytical techniques capable of identifying and quantifying nanoscale plastic particles in bivalve tissues. The study addresses the methodological challenges of isolating and characterizing nanoplastics from complex biological matrices.
Detection, counting and characterization of nanoplastics in marine bioindicators: a proof of principle study
Researchers demonstrated a proof-of-concept workflow for detecting and counting nanoplastic particles (below 1 µm) in marine invertebrate tissues using electron microscopy and spectroscopic confirmation, finding nanoplastics in marine bioindicator species and establishing a methodology for future monitoring programs.
Spectro‐Microscopic Techniques for Studying Nanoplastics in the Environment and in Organisms
This review examined spectro-microscopic techniques available for detecting and studying nanoplastics in environmental and biological samples. The study highlights that detecting nanoplastics remains challenging because their small size falls below the detection limits of common analytical tools, and their chemical composition is similar to organic matrices, making identification difficult.
Identification of microplastics in mollusks using an optical microscope
Researchers developed and tested optical microscope-based methods for identifying microplastics in mollusks following tissue digestion. The study evaluated factors affecting tissue decomposition and found that careful protocol design was essential for reliable MP detection in shellfish commonly consumed by humans.
Spectro‐Microscopic Techniques for Studying Nanoplastics in the Environment and in Organisms
This review examines spectro-microscopic techniques for detecting and characterizing nanoplastics (under 1 um) in environmental and biological matrices, arguing that effective analysis requires combining particle imaging with chemical characterization of the same particles, and highlighting methods capable of simultaneous morphological and chemical identification.
Advancements in optical techniques for direct identification and localization of micro- and nanoplastics in biological samples
Researchers reviewed advanced optical methods for directly detecting and localizing microplastics in biological tissues, highlighting techniques that can identify particles without extraction or digestion. Optical approaches including Raman mapping and coherent anti-Stokes Raman scattering allow spatial mapping of microplastics in tissue sections.

Advancements in optical techniques for direct identification and localization of micro- and nanoplastics in biological samples
This review surveyed advances in optical techniques for detecting and localizing microplastics directly in biological tissue samples, addressing the challenge that human tissue detection has not kept pace with detection in environmental matrices. Emerging methods including Raman microspectroscopy and CARS microscopy were identified as most promising for tissue-level microplastic identification.

Researchers detected nano- and microplastics in mammalian tissue samples using sensitive analytical techniques, confirming particle accumulation in organs beyond the gastrointestinal tract. The findings demonstrate that small plastic particles can translocate from the gut to systemic tissues.
DEVELOPMENT OF A NOVEL PROTOCOL FOR THE EXTRACTION OF SMALL MICROPLASTICS (1-5 µm) FROM BIOLOGICAL TISSUES
Researchers developed a novel extraction protocol to isolate and quantify small microplastics (1–5 µm) from biological tissues, addressing a major gap in marine contamination studies. The method improves detection of these hard-to-analyze particles, which are more likely to penetrate cells and accumulate in organisms.

Researchers validated a protocol for identifying and quantifying polyethylene microplastics in biological samples, finding that membrane filtration caused particle retention problems and that flow cytometry offered a more reliable alternative for analysis of biological digests.
Optical photothermal infrared spectroscopic assessment of microplastics in tissue models and non-digested human tissue sections
Researchers developed a method using optical photothermal infrared spectroscopy to detect and map microplastics directly within tissue sections without requiring chemical or enzymatic digestion. The study suggests this approach preserves spatial information about where microplastics are located within tissue architecture, overcoming a key limitation of conventional digestion-based methods that can lose some particles.
