Determination of N-acetylation degree in chitosan using Raman ...
2015年1月5日 · Application of Raman spectroscopy in determination of the acetylation degree (DA) of chitosan has been developed. The spectra of several chitosan samples characterized by different DD (degree of deacetylation) in the range 50–100% have been measured.
raman spectra of chitosan samples before and after cross …
We present a study of a range of cross-linked chitosan composites with potential antimicrobial applications. They were formed by cross-linking chitosan and siloxane networks and by introducing...
Raman spectra of (a) chitosan, (b) zinc oxide and (c) CAZO NRs.
Raman spectra of (a) chitosan, (b) zinc oxide and (c) CAZO NRs. Chitosan adorned zinc oxide nanorods (CAZO NRs) were synthesized by a chemical conversion method. The synthesis was carried...
Raman spectra of pure components: chitosan and 1,3-β-D …
Raman spectroscopy allowed observation of O-CC, C-O-C, C-C=O, and C-N=C bands that were assigned to chemical interactions between chitosan and 1,3-β-D-glucan, forming interconnections between...
Surface Chemical and Morphological Analysis of Chitosan/1,3-β- d ...
The most prominent bands detected in the Raman spectra of chitosan, 1,3-β-d-glucan, and chitosan/1,3-β-d-glucan films cross-linked at 90 °C.
Chitosan supported silver nanostructures as surface-enhanced Raman …
2023年12月31日 · In this work, nanostructures comprising silver nanoparticles supported on a wrinkled chitosan matrix (Ag@Ch) were successfully synthesized by a simple aging process at room temperature for four days through self-assembly.
Chitosan and Its Carboxymethyl-Based Membranes Produced by …
2023年8月10日 · The materials we obtained were studied by infrared and Raman spectroscopy methods, including using a confocal Raman microscope for mapping their surface. Electron absorption and emission measurements were also taken.
Raman spectra of the chitosan bulk and electrospun nanofibers.
We report the preparation of anisotropic chitosan nanofibers prepared using an electrospinning technique. The effect of electrospinning on the formation of nanofibers was examined from results of...

Extraction, Characterization, and Antimicrobial Activity of Chitosan ...
2020年8月6日 · With the aim to turn the shell waste into a useful product, this work was carried out to extract chitosan from the horse mussel (M. modiolus) and characterize chitosan by FTIR, micro-Raman spectroscopy, XRD, and elemental analysis. The antibacterial activity of the extracted chitosan was also tested against Gram-positive and Gram-negative bacteria.
