a Viability of HeLa-luc cells incubated with UCNP–PEG–FA/P–C70 at various concentrations. b Growth of tumors after treatments. The relative tumor volumes were normalized to their initial sizes. c Viability of A549, HBE, and HeLa-Luc cells incubated with either UCNP–PEG–FA/P–C70 or the mixture of UCNP–PEG–FA/P–C70 and an excess of folate (980 nm, 480 J/cm2)
