A Mini Review on Utilization of Nano Cellulose in Sensing Applications

Abstract

Cellulose is the most abundant natural polymer found in the cell walls of plants and bacteria. Nanocellulose can be obtained from cellulose and bacteria. Nanocellulose can be found in different forms such as cellulose nanocrystals (CNC), cellulose nanofibers (CNF), and bacterial nanocellulose (BNC). In modern days, nanocellulose is used in various fields. Sensors are one of the fields where nanocelluloses are widely used. The application of nanocellulose into sensing devices resulted in a notable increase in the sensing power of those devices. In order to detect toxins and other biological components, a wide variety of sensors use various forms of nanocellulose. The addition of nanocellulose into these sensors results in significant improvements to the devices' sensing power as well as their selectivity and sensitivity. In this work, we studied various toxin sensors, biosensors and the use of nanocellulose in these sensors.
