Figure 3.
2D 1H-15N CP-HSQC SSNMR spectrum of ANSII-GNPs (black) superimposed with the spectrum of crystalline ANSII (red) (panel A), and PEG-ANSII (blue) (panel B). The superimposition of the spectra of crystalline and PEG-ANSII is also reported (panel C). The spectrum of ANSII-GNPs was acquired on a 800 MHz spectrometer, while the spectra of crystalline ANSII and PEG-ANSII were acquired on a 850 MHz spectrometer. All the spectra were recorded at ~282 K and MAS of 60 kHz.
