New metamaterials produced from combining synthetic and biological nanoparticles [Registered]

Researchers from Aalto University, Finland, led by Mauri Kostiainen have succeeded in organising virus particles, protein cages and nanoparticles into crystalline materials. These nanomaterials are important for applications in sensing, optics, electronics and drug delivery. Layer structures, or superlattices, of crystalline nanoparticles have been extensively studied in recent years. The research develops hierarchically structured nanomaterials with tuneable optical, magnetic, electronic and catalytic properties. Such biohybrid superlattices of nanoparticles and proteins would allow the best features of both particle types to be combined. They would comprise the versatility of synthetic nanoparticles and the highly controlled assembly properties of biomolecules. The researchers…
