Advances　in　the　development　of　small　photoblinking　semiconducting　polymer　dots　(Pdots)　have　attracted　great　interest　for　use　in　super-resolution　microscopy.　However,　multicolor　super-resolution　imaging　using　conventional　small　photoblinking　Pdots　remains　a　challenge　due　to　their　limited　color　choice,　broad　emission　spectrum,　and　heavy　spectrum　crosstalk.　Here,　we　introduce　two　types　of　small　photoblinking　Pdots　with　different　colors　and　relatively　narrow　emission　spectra:　blue　PFO　Pdots　and　carmine　PFTBTS　Pdots　for　blinking-based　statistical　nanoscopy.　Both　of　these　probes　feature　ultrahigh　single-particle　brightness,　very　strong　photostability,　superior　biocompatibility,　and　robust　fluorescence　fluctuation.　In　addition,　these　small　photoblinking　Pdots　serve　as　excellent　labels　for　dual-color　super　resolution　optical　fluctuation　imaging　(SOFT)　of　specific　subcellular　structures,　indicating　their　promise　for　long-term　multicolor　SOFI　nanoscopy　with　high　spatiotemporal　resolution.
