【正文】 (b) Corresponding fluorescence emission spectra. Fig 2. (c) Emission peak intensity of SWNT bound FluorPEG and free FluorPEG in a fluorescein concentration range of 200900 nM. Figure 3. pHdependent fluorescence and absorbance of FluorPEG/SWNT. Absorption curves of FluorPEG/SWNT at various pHs in the (a) fluorescein region (dashed line marks the peak at pH 12) . Figure 3. (b) SWNT region (curves are displaced for clarity). Figure 3. (c) Corresponding fluorescence emission spectra (236。 SEM (E) and TEM (F) of M3. The sample of the inset of image F was negative stained with 1% phosphotungstic acid. Fig. 5 1H NMR spectra of PNIPAM(A), M3 (B) and M1 (C) in D2O at different temperatures. Fig. 6 Optical transmittance () and average hydrodynamic diameters (:) of M3 in the temperature range 20–45 C. Fig. 7 FITC release from M3 at different cycle times. After UV measurement, the fresh water was replaced and FITCM3 particles were redispersed at 20 C (:) or 40 C () for 15 minutes. The inset image illustrates the whole process. Fig. 9 CLSM of MCF7 cells stained with FM 464 and FITCM3 suspensions after 12 h of coculturing. The corresponding images of the FITCM3 (green) (A)。 MSNinitiator (c) and MSNpolymer (M1) (d).
