SEM image of FeOOH nanorods by Lan Chen
This image was obtained by Scanning Electron Microscope (SEM) and is a cluster of β-FeOOH nanorods spontaneously formed during the synthesis process, which resembles an orchid petal as shown inset. This materials can be made and tailored by the forcibly hydrolysis of Iron (III) Chloride in aqueous solution in the presence of cationic surfactant cetyltrimethylammonium bromide (CTAB). The length of a single β-FeOOH nanorod is about 205 nm and its diameter at the widest part is about 80 nm. This nanostructure can be used as the template to make drug delivery carrier for biomedicine applications due to its economic synthesis and easy de-templating.
