“…Alternatively, a number of hydrocolloids in small quantities can be used to attain the desired viscosity; however, these are usually sensitive to temperature and other factors, such as electrolyte content. Nanosized crystals (>60% of particles < 100 nm) of MCC in combination with medium‐molecular‐weight carboxymethylcellulose (CMC) have proven useful in the stabilization of various dispersive systems 94, 95. This is because nanocrystals of MCC (the major component) are water‐insoluble and, therefore, render the system with desirable thermal stability; this makes this material superior over other water‐soluble viscosity enhancers.…”

“…If no protective hydrocolloid is used, the crystallites will reagglomerate upon drying and produce an essentially nonporous, low‐surface‐area product. The produced dispersible MCC/CMC grades form thixotropic gels at solids content of 1.2% and greater 94–96. One of the main shortcomings of dispersible MCC/CMC grades is their sensitivity to electrolytes and other competitors for water, in general.…”

[94][95][96] One of the main shortcomings of dispersible MCC/ CMC grades is their sensitivity to electrolytes and other competitors for water, in general. Furthermore, whereas conventional dispersible MCC/CMC grades have been used to substantially reduce fat in food, large quantities of cellulose-based ingredients must be added to obtain a desirable consistency; this imparts adverse organoleptic properties.…”

This article represents the first attempt to summarize the knowledge about the structure and functional properties of green algae cellulose since 1885, when cellulose of algal origin was first described. Here, I systematically discuss the unique structural characteristics of Cladophora cellulose. This specific interest in Cladophora filamentous green algae is justified by unwanted global socioenvironmental problems associated with seasonal blooms by these algae. Thus, the physicochemical properties and the use of this unique material are discussed in a broad context. Several high-tech applications wherein the use of Cladophora cellulose is highly beneficial are highlighted.

Fabrication of bone substitutes, which are a combination of bio-ceramics and bio-polymer, is performed to meet the demand for bone regeneration after fracture or disease. In this study, sodium carboxymethylcellulosegelatin (NaCMC-GEL) hydrogel scaffold where the ratio of NaCMC and GEL was 1:2 and biphasic calcium phosphate (BCP) loaded NaCMC-GEL where the ratio of BCP, NaCMC and GEL was 1:1:2 hydrogel scaffold were fabricated successfully by the freeze-drying method. These hydrogel scaffolds were crosslinked by 0.75wt% genipin solution to check the swelling and ensure optimum degradation. Then BCP-NaCMC-GEL hydrogel was coated with recombinant human bone morphogenetic protein-2 (rhBMP-2). Detailed morphological and material characterization, such as porosity, micro-structural analysis, and chemical constituents of NaCMC-GEL and BCP-NaCMC-GEL hydrogel scaffolds was carried out. The study demonstrates that these hydrogel scaffolds have a porous structure and the pore size is optimum for bone tissue regeneration. PBS uptake and degradation behavior of the NaCMC-GEL, BCP-NaCMC-GEL and BMP-2-BCP-NaCMC-GEL hydrogel scaffolds were also observed. BMP-2-BCP-NaCMC-GEL hydrogel scaffold showed higher cell viability, cell attachment, and proliferation of pre-osteoblast MC3T3-E1 cells than the NaCMC-GEL, BCP-NaCMC-GEL scaffolds, which was confirmed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay, live-dead assay, and immunofluorescence assay. The BMP-2 release profile from BMP-2-BCP-NaCMC-GEL scaffold was also shown. The observations show that BMP-2-coated BCPNaCMC-GEL hydrogel scaffold is a promising material for bone tissue regeneration.
