Abstract：

As　an　emerging　environmental　pollutant，nanoplastics　are　small　in　size　and　easy　to　enter　organisms　through　biological　barriers，causing　potential　harm　to　human　health.　Polystyrene　nanoparticles　（PSNPs）　as　a　typical　representative，are　widely　used　in　the　toxicological　research　of　nanoplastics.　However，due　to　the　lack　of　traceable　properties，research　progress　on　the　behavior　of　PSNPs　in　vivo　has　been　slow.　Therefore，a　kind　of　PSNPs　with　long　after　glow　nanoparticles　was　designed　and　synthesized.　The　PSNPs　consist　of　near-infrared　long　afterglow　nanomaterials　Zn1.3Ga1.4Sn0.3O4：Cr3+，Y3+　（ZGS）　as　the　core　and　PS　as　the　shell，forming　a　core-shell　structure　ZGS@PS.　The　synthesized　PSNPs　have　good　dispersion　and　regular　spherical　morphology，and　produce　excellent　near-infrared　long　afterglow　emission　at　700　nm　after　excitation　by　red　LED.　The　in　vivo　imaging　results　show　that　PSNPs　can　be　traced　in　mice　for　a　long　time　by　means　of　near-infrared　long　afterglow　generated　by　PSNPs，which　provides　a　good　tracing　tool　for　the　study　of　PSNPs　in　vivo　behavior.　©　2025　Editorial　Office　of　Chinese　Rare　Earths.　All　rights　reserved.
