The present study provides a dimensional analysis of the magnetic nanoparticles size within water based magnetic fluids, prepared in our laboratories, as obtained from transmission electron microscopy (TEM) and atomic force microscopy (AFM). The magnetic nanoparticles were prepared by chemical co-precipitation from ferric (FeCl3) and ferrous salts (FeCl2) in alkali medium (ammonia hydroxide) and functionalized with tartaric acid, β-cyclodextrin, perchloric acid and respectively, citric acid. The TEM images have been analyzed aiming to reveal diameter distribution histograms. The AFM was used to visualize and measure the magnetic nanoparticles diameter and height – the 3-D imaging representing one of the main advantages of this scanning technique. The suitability of the aqueous magnetic fluids for biomedical applications was discussed.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
