Chitin and its derivative chitosan exhibit notable resistance to radiation, which has implications for their use in various applications, including biomedical fields. Research indicates that chitin and chitosan maintain their structural integrity and functional characteristics even when exposed to significant doses of gamma radiation. This resilience is crucial for their potential use in environments where radiation exposure is a concern.
Protective Effects Against Radiation
- Gamma Radiation Resistance: Chitin and chitosan do not undergo significant radiolysis when irradiated, maintaining their structural properties even at doses up to 50,000 krad(Muzzarelli & Tubertini, 1972).
- Antimicrobial Properties: Chitin-nanosilver membranes retain their antimicrobial efficacy against various pathogens post-irradiation, indicating that their functional properties are preserved(Singh et al., 2015).
Structural Integrity
- Molecular Weight and Chain Scission: While gamma irradiation can lead to chain scission in chitosan, resulting in decreased molecular weight, this process can enhance certain properties like water solubility and antimicrobial activity(Rashid et al., 2012).
- Thermal Properties: The thermal stability of chitosan is affected by irradiation, with changes in glass transition temperature observed, which may influence its application in biomedical fields(Lim et al., 1998).
Despite these advantages, the potential for degradation under extreme conditions remains a concern, necessitating further research to optimize the use of chitin and chitosan in radiation-prone environments.Read LessSave to NotebookAPA, Bullets Find TopicsAdd columns (1)
