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.
Plasmonic Detection of Microplastics and Microorganisms Using a Circular-Nanorod-Coupled MIM Sensor
AI summary Read the abstract
Researchers designed a compact plasmonic sensor based on a silver metal-insulator-metal waveguide coupled to an octagonal cavity embedded with circular nanorods, achieving dual resonance sensitivities of 1,321 and 2,198 nm/RIU that enable optical detection of microplastics and aquatic microorganisms through refractive index shifts.
Recent Progress in Electrochemical Methods for Microplastics Detection

Researchers reviewed advances in electrochemical sensor technology for detecting microplastics and nanoplastics, highlighting the method's potential as a fast, cost-effective, and field-deployable alternative to conventional laboratory analysis.
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.
