Claim:
1. A method of patterning nanocellulose, comprising: laminating a sheet of nanocellulose onto a backing substrate, applying a conformal resist coating to the nanocellulose to create a first mask patterned layer having blank areas where the nanocellulose is not covered by the conformal resist coating, depositing a layer of inorganic material in the blank areas to create a pre-etch structure comprising a pattern of the inorganic material atop the sheet of nanocellulose, in turn atop the backing substrate, removing the first mask pattern layer from the pre-etch structure, and then etching to remove portions of the nanocellulose in a pattern corresponding to the first mask pattern, thereby creating patterned nanocellulose.
