Figure 2From: A systematic study of core size and coating thickness on manganese-doped nanocrystals for high T2 relaxivity as magnetic resonance contrast agent TEM images of MnFe 2 O 4 magnetic nanocrystals (MnMNCs) at the same magnification. The average diameters of the MnMNC, obtained by measuring about 50 particles for each sample, (a) MnMNC6 (b) MnMNC12. All scale bars are 20 nm.Back to article page
