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.
