文摘

Magnetoelastic resonance (MER) makes wireless measurements in-vivo possible. Resonance frequency change on pH induced volume changes is due to trapped liquid. pH response of functional polymer can be expected to vary between different liquids. Mussel foot protein 1, mfp-1, enables simple and robust surface-bead attachment. Mfp-1 enables use of a generic protocol for Layer-on-layer architecture.
