This new study has introduced a game-changing method for detecting microplastics and it's simple, portable, and cost-effective!
๐ก Researchers developed a flexible SERS substrate made of gold nanostars on filter paper to identify microplastic particles as small as 0.5 ฮผm.
Highlights:
๐น Detection limit as low as 5 ยตg/mL
๐น ~1300x signal enhancement using standard Raman equipment
๐น Successfully detected multiple types of microplastics: polystyrene, polyethylene, polypropylene, and PET
๐น Ideal for real-world monitoring in aquatic environments
Why it matters: Traditional microplastic detection is expensive and complex. This approach could revolutionize environmental monitoring with a sensitive, low-cost, and field-ready solution.
