(a,b) Time-dependent changes in NBD fluorescence intensity of PINCs in DI water over a 48-hour period at 37 °C. (c) Fluorescence intensity of supernatant (sup) vs. redispersed pellet collected by centrifugation after 15-day incubation in water at 4 °C. (d,e) Time-dependent changes in C* fluorescence of PINCs in 50% (v/v) FBS solution over a 48-hour period at 37 °C. (f) Fluorescence intensity of supernatant (sup) vs. redispersed pellet collected by centrifugation after 48-hour incubation in 50% (v/v) FBS solution at 37 °C.
