Fig. 1From: The neuroprotective effect of pretreatment with carbon dots from Crinis Carbonisatus (carbonized human hair) against cerebral ischemia reperfusion injuryA Transmission electron microscopy (TEM) image of carbon dots from Crinis Carbonisatus (CrCi-CDs). (magnification ×160,000), the accelerating voltage was 100 kV. B, C High-resolution TEM (HRTEM) images of individual CrCi-CDs. E UV–visible spectra of CrCi-CDs. F Emission spectra Excitation spectra of CrCi-CDs with different emission wavelengths of CrCi-CDs excited at 360 nm. G Fourier transform infrared (FTIR) spectrum of the CrCi-CDs (32 scans at 2 cm−1 resolution in the scanning range of 500–4000 cm−1). H–K Elemental analysis of CrCi-CDsBack to article page
