Polysaccharides derived from natural sources applied to the development of chemically modified electrodes for environmental applications: A review

Polysaccharides; Classification, Chemical Properties, and Future Perspective Applications in Fields of Pharmacology and Biological Medicine (A Review of Current Applications and Upcoming Potentialities)

“…Mushrooms have been used for a long time, and recently they have gained more importance in cancer therapy, polysaccharides derived from mushrooms such as chizophyllan, lentinan, grifolan, polysaccharide-peptide complex (PSP), and polysaccharide-protein complex (PSK) can induce the immune response and produce the antitumor effect, which makes them promising candidates against tumor in the future [ 79 ]. The safety of polysaccharides is a crucial factor, and a strong advantage that will make the use of their increase in the future, many other organic synthesis and chemical modifications caused severe environmental pollution which could be improved by substitution to natural polysaccharides [ 108 ]. From the drug delivery perspective, and due to their biocompatibility and biodegradability properties, polysaccharides have been increasingly used in many different forms to control the delivery of some drugs [ 109 ].…”

An Innovative Sensor Based on Chitosan and Graphene Oxide for Selective and Highly‐Sensitive Detection of Serotonin

“…[7] These properties represent the foundation which allows additional functionalization paving the way for multiple applications in various fields including the field of sensors for biomedical, environmental, and industrial applications. [6,[8][9][10] Graphene oxide (GO) represents the advanced graphene derivative often applied for sensors development mainly due to its high conductivity and large surface area. The particular surface properties of GO such as oxygenated functional groups on the basal planes and edges, large surface area and layered structure, makes it suitable for the elaboration of functional composite materials for sensors with increased performances.…”

Voltammetric Sensor Based on Molecularly Imprinted Chitosan-Carbon Nanotubes Decorated with Gold Nanoparticles Nanocomposite Deposited on Boron-Doped Diamond Electrodes for Catechol Detection

“…The employment of one biocompatible amino-polysaccharide derived from the shells of crustaceans, chitosan (CS) presents some advantages due to its non-toxic activity and excellent permeability; moreover, it has an excellent layer forming ability. However, due to the high degree of crystallinity that the polymer has, conductivity is low, which hinders the redox process [16]. To overcome these drawbacks, the formation of a nanocomposite including nanomaterials with electroactive functionality is of great interest in the development of electrochemical sensors, due to the fact that nanomaterials-such as carbon nanotubes (CNT), metal nanoparticles (MNP), graphene, phthalocyanines metal nanowires, and metal nanorods among others-can improve the electron transfer between the electrode surface and the solution, working as electron mediators [17].…”
