Abstract
The present invention relates to nanoparticles and their use to form nanocomposite material, in particular bionanocomposite material, specifically wherein the nanoparticles are formed using plant virus attached to a scaffold of cellulosic material and/or cellulose derived materials, in particular wherein said cellulosic material further comprises plant cell components, for example hemicellulose, pectin, protein or combinations thereof.
Claims12
A nanocomposite material comprising:
- a) a nanocellulose scaffold, wherein the nanocellulose scaffold is a non-virus scaffold, and wherein the nanocellulose scaffold comprises a nanocellulose material and, cellulose platelets;
- and
- b) at least one virus particle, virus-like particle, or structure formed from virus components, wherein the at least one virus particle, virus-like particle, or structure formed from virus components comprises the coat protein of the tobacco mosaic virus,
- wherein the at least one virus particle, virus-like particle or structure formed from virus components is modified to provide surface displayed functional peptides, whole proteins, or enzymes on the surface of the virus particle, virus-like particle, or structure,
- wherein the at least one virus particle or virus-like particle is bound to the nanocellulose scaffold
- wherein the cellulose platelets comprise at least 60% cellulose by dry weight, less than 10% pectin by dry weight, and at least 5% hemicellulose by dry weight,
- wherein the hemicellulose comprises xyloglucans, xylans, mannans and glucomannans.
