Salt-Induced Nano-Trapping for Ultra-Sensitive Sers Detection of Nanoplastics in Drinking Water

Nanotechnology-enabled analytical tools for Microplastics and nanoplastics in aquatic ecosystems

AI summary · Read the abstract

Tiny plastic particles in our water, some smaller than a virus, have been hard to detect with older lab tools, making it tough to know how much is really out there or how it might affect us. This review rounds up new nanotech-based detection methods (using gold nanoparticles, light-scattering sensors, and AI) that can spot these nanoplastics at incredibly low levels, faster and with less environmental impact than traditional testing. Better detection tools like these are a key first step toward understanding plastic pollution's health risks and building policies to protect our water supplies.

A Highly Sensitive SERS Substrate for Detection of Nanoplastics in Water

AI summary · Read the abstract

Researchers developed a highly sensitive SERS-based substrate for detecting nanoplastic particles in water at very low concentrations. Improved detection tools for nanoplastics are essential for monitoring their presence in drinking water and understanding exposure risks to human health.

Rapid and low-cost detection platform for micro- and nanoplastics

Modified hydrogel for high efficiency SERS detection and adsorption removal of microplastics

AI summary

Researchers developed a modified hydrogel material capable of both detecting and capturing microplastics using surface-enhanced Raman spectroscopy (SERS). The hydrogel's porous structure allows it to adsorb microplastic particles from water while SERS provides sensitive, rapid identification of plastic types. This dual-function approach offers a promising tool for environmental monitoring and microplastic removal from water systems.

Capturing, enriching and detecting nanoplastics in water based on optical manipulation, surface-enhanced Raman scattering and microfluidics

AI summary · Read the abstract

Scientists built an optical manipulation and surface-enhanced Raman scattering system using gold nanoparticle stacks to simultaneously capture, enrich, and detect nanoplastics in natural water at concentrations as low as 150 ng/L for polystyrene, successfully quantifying nanoplastics across river, mariculture, and beach water samples. The technique fills a critical measurement gap for nanoplastics, enabling reliable concentration monitoring in environments where these particles are otherwise nearly impossible to detect and quantify.
