We　propose　a　nanoparticle　transportation　method　in　a　dielectric　metasurface　for　nanoparticles　of　particular　sizes　using　rotatable　linearly　polarized　light.　The　dielectric　metasurface　utilizes　plum-blossom　structures　to　realize　hot　spot　position　switching　by　rotating　the　polarization　state　of　incident　light.　The　convex　point　of　the　plumblossom　dielectric　metasurface　always　has　a　hot　spot　with　higher　intensity　than　that　in　the　concave　point,　and　there　is　an　unbalanced　potential　well　between　the　two　adjacent　plum-blossom　dielectric　metasurface　units　so　that　the　nanoparticles　are　more　easily　attracted　and　transferred　to　the　adjacent　unit　with　a　deeper　potential　well.　By　cascading　many　single　plum-blossom　dielectric　metasurface　units　into　an　array,　the　array　forms　a　one-way　multichannel　optical　control　dielectric　metasurface　conveyor　belt,　which　can　realize　nanoparticle　capture　and　transmission.　It　can　deliver　the　nanoparticles　along　the　designated　route　in　a　dielectric　metasurface.　The　design　has　great　potential　for　optical　flow　control　chips,　which　can　achieve　more　stable　nanoparticle　transport　through　the　action　of　rotating　linearly　polarized　light.　©　2025　Optica　Publishing　Group.　All　rights,　including　for　text　and　data　mining　(TDM),　Artificial　Intelligence　(AI)　training,　and　similar　technologies,　are　reserved.
