    Abstract : Water-based suspensions of single-core iron-oxide particles with nominal sizes 15 - 50 nm were studied by AC and DC magnetometry techniques, in order to determine their suitability for use in the volume amplified nanobead detection assay (VAM-NDA). The VAM-NDA can detect specific bio molecules, which have been magnetically tagged and volume amplified, by measuring the difference in the Brownian relaxation rate compared to a negative control sample.
