“…The results showed that the gas content transmitting through dressing per unit time increased with the pressure, reaching up to 3605.22 ± 8.26 mm/s under the pressure of 500 Pa ( Table S3 ), which featured the highest level of breathability among the reported hydrogel dressings and even comparable to gauze ( Fig. 3 j) [ [50] , [51] , [52] , [53] , [54] , [55] ].…”

“…The TiO 2 particles were entrapped between cotton fibers, which hindered the moment of fibers. These particles helped to share the external load, which resulted in higher strength [ 60 ]. Moreover, when CN was coated with cellulose hydrogel, elongation increased, but when CNHG was coated with TiO 2 , elongation decreased due to minor rigidity of the TiO 2 layer.…”

Hydrogels wound dressings have enormous advantages due to their ability to absorb high wound exudate, capacity to load drugs, and provide quick pain relief. The use of hydrogels as wound dressings in their original form is a considerable challenge, as these are difficult to apply on wounds without support. Therefore, the incorporation of polymeric hydrogels with a certain substrate is an emerging field of interest. The present study fabricated cellulose hydrogel using the sol–gel technique and reinforced it with nonwoven cotton for sustainable wound dressing application. The nonwoven cotton was immersed inside the prepared solution of cellulose and heated at 50 °C for 2 h to form cellulose hydrogel–nonwoven cotton composites and characterized for a range of properties. In addition, the prepared hydrogel composite was also loaded with titania particles to attain antibacterial properties. The Fourier transform infrared spectroscopy and scanning electron microscopy confirmed the formation of cellulose hydrogel layers inside the nonwoven cotton structure. The fabricated composite hydrogels showed good moisture management and air permeability, which are essential for comfortable wound healing. The wound exudate testing revealed that the fluid absorptive capacity of cellulose hydrogel nonwoven cotton composite was improved significantly in comparison to pure nonwoven cotton. The results reveal the successful hydrogel formation, having excellent absorbing, antimicrobial, and sustainable properties.

“…The FT-IR spectra of SA are shown in Figure 1 A. The stretching vibrations of the O–H and C–H bonds are assigned at 3423.58 cm −1 and 2925.67 cm −1 , respectively [ 35 ]. The peaks near 1437.23 cm −1 were caused by symmetric and asymmetric stretching vibrations of COO– groups.…”

“…In Figure 1 A CS, the peak at 3423.42 cm −1 is attributed to the O–H stretching vibrations. The bending vibration of N–H and the stretching vibration of C=O are observed at 1597.68 cm −1 and 1654.42 cm −1 , respectively [ 35 , 36 ]. The peaks at 1258.15 cm −1 and 1064.33 cm −1 represent C–O stretching vibrations, which are common structures in CS.…”

This research underlines the potential of alginate multilayered gel microspheres for the layered encapsulation and the simultaneous delivery of vitamin B2 (VB) and β-carotene (BC). Chitosan was used to improve the stability and controlled release ability of alginate-based gel microspheres. It was shown that a clear multilayered structure possessed the characteristics of pH response, and excellent thermal stability. The sodium alginate concentration and the number of layers had notable effects on mechanical properties and particle size of gel microspheres. Fourier-transform infrared spectroscopy and X-ray diffraction analyses further proved that VB and BC were encapsulated within the gel microspheres. Compared with the three-layer VB-loaded gel microspheres, the total release of VB from the three-layer VB and BC-loaded gel decreased from 93.23 to 85.58%. The total release of BC from the three-layer VB and BC-loaded gel increased from 66.11 to 69.24% compared with three-layer BC-loaded gel. The simultaneous encapsulation of VB and BC in multilayered gel microspheres can markedly improve their bioaccessibility and bioavailability. These results showed the multilayer gel microspheres synthesized herein have potential for applications in the layered encapsulation and simultaneous delivery of various bioactive substances to the intestinal tract.
