Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale. Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals. Nanocellulose may be obtained from natural cellulose fibers through a variety of production processes.
Nanocellulose is instead derived from wood pulp that has been processed to create extremely small, nanoscale fibers. These fibers can be used to create a hydrogel, which is a type of material that is made up of a network of cross-linked polymer chains and is able to hold large amounts of water.
Bioprinting drug delivery is a method for producing drug delivery vehicles. It uses three-dimensional printing of biomaterials via additive manufacturing.Such vehicles are biocompatible, tissue-specific hydrogels or implantable devices. 3D bioprinting prints cells and biological molecules to form tissues, organs, or biological materials in a scaffold-free manner that mimics living human tissue.
The resulting nanocellulose films, which have a Bouligand structure, can be manipulated to achieve various effects on the material properties. These nanocellulose films are impact-resistant, sustainable, and multi-functional and can be used in various applications such as stretchable electronics, protective coatings, eyewear, and body armor.
Curran is a microcrystalline nanocellulose fibre derived from the pulp of root vegetables. It was developed by Scottish scientists David Hepworth and Eric Whale, with funding from the Scottish Government. The sources of root vegetable pulp used to manufacture Curran include carrots, sugar beets, and turnips.
In August, 2012, the FPL unveiled a $1.7 million production facility for renewable, forest-based nanomaterials. This facility is the first of its kind in the United States and one that positions the laboratory as the country's leading producer of nanocellulose materials. Nanocellulose is simply wood fiber broken down to the nanoscale.

Cranston returned to Canada in 2011, and joined the faculty at McMaster University.Her research considers the colloid and surface chemistry of biopolymers. [3] She has particularly focused on the development of nanocellulose microstructures [4] that can be used in a broad range of applications, including packaging, electrical components and cosmetics.
