摘      要：Folic acid and D-gluconic acid-capped gadolinium oxide nanorods and nanocuboids were synthesized via co-precipitation *** study of relaxivity factor on the role of capping and morphology for enhancing contrast ability for T_(1) and T_(2) magnetic resonance imaging(MRI) was *** obtained r_(2)/r_(1) ratio for folic acid and D-gluconic acid-capped gadolinium oxide nanorods and nanocuboids was 1.5 and 1.3,*** nanocrystals were characterized and presented with properties such as good dispersity and stability required for standard contrast agent used in *** characterization and the analysis of capping agent for nanocrystals suggest the preferable use of carbohydrate moieties with higher number of hydroxyl functional group reacted with urea and hydrogen peroxide for desired morphology and anisotropic ***-differential thermal analysis(TG-DTA) illustrated the amount of capping,transition temperature from Gd(OH)3 to GdOOH and crystallization temperature from GdOOH to *** nanocrystals would be significant for other biomedical applications such as drug delivery when equipped with well-functionalized drug molecules.
