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. Plasmonic techniques, surface plasmon resonance (SPR) surface-enhanced spectroscopy (SERS), high sensitivity nanostructure-enhanced detection. Fluorescent utilizing microbial enzymatic elements enable the real-time monitoring plastic degradation products, terephthalic acid polyethylene terephthalate (PET). Advancements innovative approaches pave way more accurate, scalable, environmentally compatible solutions, contributing improved remediation strategies. This review highlights advanced section on prospects that address could lead significant advancements monitoring, highlighting necessity testing new sensing developments under real conditions (composition/matrix samples), which overlooked, well study peptides novel recognition element microplastic sensing.

Nanoplastics, novel environmental pollutants widely dispersed, present challenges due to limited, dependable detection methods, particularly for trace levels. This study introduces a approach that integrates liquid-phase self-assembly nanoparticle technology with surface-enhanced Raman spectroscopy (SERS) the precise of nanoplastics. Utilizing hydrophobic–lipophilic interactions and SERS technology, we developed silver nanoparticles (Ag NPs)@poly(methyl methacrylate) (PMMA) films NPs@PMMA films) efficient extraction simultaneous polystyrene (PS) polyethylene terephthalate (PET) nanoplastics at extremely low concentrations (e.g., 10–11 mg/mL 20 nm PS 10–8 70 PET nanoplastics). It also demonstrates linear correlation between intensity (y) logarithm nanoplastics' concentration (lg c) technique's applicability extends real samples, such as seawater, oysters, bottled water, enabling both qualitative quantitative For example, it successfully identifies 1.23 × 10–10 in seawater samples 8.61 10–5 bottled-water samples. Overall, these findings provide reliable basis nanoplastic environment, addressing pressing concern.
