Effect of bassorin (derived from gum tragacanth) and halloysite nanotubes on physicochemical properties and the osteoconductivity of methylcellulose-based injectable hydrogels

Nanocomposite Hydrogel Produced from PEGDA and Laponite for Bone Regeneration

“…For example, a study showed that nano-hydroxyapatite (n-HA)/glycol chitosan (G-CS)/hyaluronic acid (HyA) hydrogels were cytocompatible and nontoxic, with excellent potential for application in bone tissue engineering [ 2 ]. Another study with thermosensitive methylcellulose (MC) hydrogels containing bassorin (Ba) and halloysite nanotubes (HNTs) achieved excellent proliferation, differentiation, cellular mineralization, and bone cell-specific gene expression [ 3 ]. A study produced nanocomposite hydrogels of chitosan, modified halloysite nanotubes, and icariin, and found that the biocompatibility improved the in vivo bone formation and the differentiation of encapsulated cells [ 4 ].…”

A forsterite-reinforced polypropylene fumarate/methoxy polyethylene glycol-hydrogel enriched with flavonoid nanoparticles enhances osteoconductivity

“…This can be associated with a tighter network structure formed by Fs NPs and the hydrogen bond formation between the Fs NPs and the hydrogel network. 30,35 As can be observed from the figure, the PPF-MPEG hydrogels demonstrated lower swelling ratios at a lower concentration (4% w/v) than PPF-MPEG-6. As the polymer concentration decreases, fewer groups are available to form hydrogen bonds, which can explain the lower swelling ratio observed.…”

“…The compressive test was conducted in triplicate for each sample, and the compressive strength and compressive modulus were determined based on the stress–strain curve. 35,36…”

“…The test was performed in triplicates. 35 Mechanical properties. Mechanical properties were evaluated by conducting compressive tests on hydrogels using a standard testing machine (SANTAM, STM-20, Iran).…”

Water-resistant gum-based phase change composite for thermo-regulating insulation packaging

“…The incorporation of BC or Cloisite Na + did not change the pore geometry considerably, yet consistent with the literature [31], the PCC with additives revealed a denser and more uniform microstructure compared with the particle-free samples. The average pore size decreased from 130 ± 40 μm for PCC3 to 28 ± 10 μm for PCC-B2 (Table 2), which could be due to its higher dry mass as well as its highly dense, robust, and well-developed network structures resulting in the creation of pores with smaller sizes [25,32]. Furthermore, no evidence of phase separation was observed in all PCCs, and the particles were distributed homogeneously in most PCCs.…”
