Introduction – What are bio-based nanomaterials? Nanomaterials are generally defined as materials having dimensions in the nanometer scale, usually between one to 100 nm. Nanometer is 10-9 meter and 1/100 of the width of the human hair. Nanomaterials cannot be seen with naked eye but high-resolution microscope is needed for this purpose. The length of
