Abstract：

Nanoplastic　particles　(NPPs)　have　attracted　lots　of　attention　due　to　their　toxicity.　In　this　study,　a　Surface-enhanced　Raman　scattering　(SERS)-based　category　on　selectivity　and　quantification　detecting　the　polystyrene　(PS)　NPPs　has　been　presented.　Firstly,　the　size-dependent　SERS　relationship　between　the　diameter　of　Ag　nanocavities　(AgNCAs)　and　the　diameter　of　the　PS　NPPs　is　studied.　By　continuously　dripping　the　PS　NPPs　on　proposed　AgNCAs　substrates,　AgNCAs　exhibit　excellent　enrichment　capability　with　a　promoted　limit　of　detection　(LOD)　of　0.001　mg/mL.　Secondly,　thermally　evaporated　Ag　nanoparticles　(AgNPs)　as　an　enhancement　layer　are　used　to　form　the　AgNPs/PS　NPPs/AgNCAs　sandwich　structure　with　a　SERS　enhancement　of　300　%.　Thirdly,　a　SERS　microfluidic　chip　constructed　by　integrating　two　kinds　of　pore　size　(87　nm　and　356　nm)　AgNCAs　is　fabricated　to　selectivity　quantifying　absolute　concentration　of　the　mixed　PS　NPPs　with　different　diameters　in　a　mixed　solution.　It　shows　excellent　performance.　This　novel　category　proves　a　good　method　for　identifying　plastic　nanoparticles　and　analyzing　their　size　distribution　existing　in　the　surroundings　indicating　good　practical　applications.　©　2024　Elsevier　B.V.
