23_12/2013Biomimetics: Virus-Tethered Magnetic Gold Microspheres with Biomimetic Architectures for Enhanced Immunoassays (Adv. Funct. Mater. 12/2013)

Inspired by the cellular threadlike structures, virus-decorated gold microspheres with high surface to volume ratios are described by Chang Su Jeon, Inseong Hwang, and Taek Dong Chung on page 1484. The filamentous viral scaffold allows dense modification with antibodies, while the thin gold layer protects non-specific bindings from serum samples, resulting in a significant increase in sensitivity in the bead-based immunoassay.
