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.
