Recently, a paper was employed in the production of more complicated microfluidic analytical devices, called lab-on-a-chip (LOC) devices, which are also used in diagnostics. Using paper to make LOC devices instead of polydimethylsiloxane (PDMS) and glass can decrease cost and size while increasing portability. This allows LOC devices to become ...
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.

Once the paper plies were saturated with the gelatinizing zinc chloride, they were pressed together. The pressing allowed intimate contact of the cellulose fibres, thus promoting bonding between the cellulose chains. Once the bonding was established, the process of leaching out the zinc chloride from the vulcanized fibre could begin.
Since the last quarter of the 20th century, phenolic resin and cellulose based compound materials have been used as an alternative to ebony and rosewood to make stringed instrument fingerboards. [3] From 2012 to 2018 guitarmaker Gibson used Richlite , a paper composite material, for the fingerboard on several top-of-the-line production guitars.
Carboxymethyl cellulose (CMC) or cellulose gum [1] is a cellulose derivative with carboxymethyl groups (-CH 2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used in its sodium salt form, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a ...
A wet microbial cellulose pellicle being removed from a culture Nata de coco, a traditional food product from the Philippines made from fermenting coconut water with Komagataeibacter xylinus. Bacterial cellulose is an organic compound with the formula (C 6 H 10 O 5) n produced by certain types of bacteria.
Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...
