Polysaccharide of moving animals. Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms, and is said to be the most abundant organic molecule on Earth. It has many uses such as a significant role in the paper and textile industries, and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose. Chitin has a similar structure, but has nitrogen-containing side branches, increasing its strength. It is found in arthropod exoskeletons and in the cell walls of some fungi. It also has
Fluorescent glucose biosensor addition to the fluorophore(s), a molecule that confers glucose specificity, in general, a protein. A variety of proteins have been used for this purpose, often with different labs concentrating on one particular protein. The first glucose biosensor reported in the literature was made in 1982 by Schultz’group using a competition assay between glucose and a labelled glucose polymer for the binding site of Concanavalin A entrapped in a hollow dialysis fibre. As a result, Con A was widely used in subsequent sensors in several labs, however Con A suffers from the downside of high toxicity and low reversibility. As a
