Preparation and Characterization of Films Based on Alginate and Aloe Vera

Development of novel alginate based hydrogel films for wound healing applications

“…S1). The first endothermic peak (69.53 • C) is attributed to the water loss of hydrophilic polymer groups, while the second one (187.56 • C) corresponds to the alginate melting temperature [9,42,43]. The exothermic peak appearing at 242.93 • C is attributed to the polymer degradation [9,43], as can be confirmed by the TGA analysis ( Supplementary Fig.…”

“…The CH vibration band occurs at 2935 cm −1 and 1420 cm −1 , which can be overlapped with the COO vibration bands. The band from the C O C stretching occurs around 1051 cm −1 and a large absorption band at 3388 cm −1 , due to the stretching vibration of OH group [9,38,39].…”

Synthesis and characterization of guar-alginate hybrid bead templated mercury sorbing titania spheres

“…Other relevant peaks were observed at 2923 cm −1 (C-H stretching at polysaccharides) and below 1000 cm −1 (from TiO 2 ) [27]. The peaks between 500 and 900 cm −1 can be ascribed to absorption bands of Ti-O and O-Ti-O flexion vibration [28]. A broad peak ranging from 500 to 800 cm −1 is characteristic absorbance of O-Ti-O network in TiO 2 [29].…”

Photocrosslinkable Materials for the Fabrication of Tissue-Engineered Constructs by Stereolithography

“…When compared to synthetic polymers, these materials offer several advantages including biological signaling, cell adhesion and cell responsive degradation [87]. The main drawbacks of natural polymers regards the limited stability of its mechanical properties, low processing window and the risk of immune rejection [42,86,87,96]. The use of these materials on stereolithography is still in its infancy, despite recent advances on the modification of natural polymers to allow its photo-crosslinking.…”
