Geckos　have　adapted　to　the　complicated　natural　environment　with　its　excellent　climbing　ability.　Current　artificial　gecko-inspired　synthetic　adhesives　(GSAs)　mimic　gecko＇s　attach-detach　mechanism　by　creating　anisotropic　and　hierarchical　structures.　Easy　detachment　and　high　self-cleaning　capability　are　still　the　unsolved　problems　in　GSAs.　This　study　presents　an　unprecedented　photo-detachable　mechanism　of　making　bioinspired　smart　surfaces　utilizing　carbon　dot　(CD)-doped　polydimethylsiloxane　(PDMS)　composites.　Under　ultraviolet　(UV)　irradiation,　it　could　be　triggered　up　to　80.46%　reduction　of　adhesion　force　between　PDMS-CDs　bioinspired　surfaces　and　contaminating　particles.　A　load-drag-pull　(i.e.,　LDP)　test　mimicking　gecko＇s　locomotion　was　adopted　to　test　the　dry　self-cleaning　capabilities　of　these　bioinspired　surfaces,　where　the　falling　rate　of　the　model　contaminates　(PS　micropellets;　average　size　in　diameter　similar　to　8　mu　m)　can　reach　up　to　54.83%　after　seven　repeated　steps　under　UV　irradiation.　The　significantly　improved　dry　self-cleaning　capability　is　attributed　to　the　photothermal　effect　of　CDs　inside　the　PDMS　matrix.　The　mechanism　proposed　in　this　work　will　find　its　applications　in　the　realms　of　climbing　robots,　space　adhesive　devices,　and　self-cleaning,　advanced　gripping　technologies　for　pick　and　place　or　assembly.
