Magnetic carboxymethyl cellulose/silk fibroin hydrogel embedded with halloysite nanotubes as a biocompatible nanobiocomposite with hyperthermia application

Fabrication of a magnetic alginate-silk fibroin hydrogel, containing halloysite nanotubes as a novel nanocomposite for biological and hyperthermia applications

“…As illustrated in the FT-IR spectrum of synthesized biocomposite in Fig. 1 a(ii), the two distinctive peaks of HNTs that arose at 3717 and 3618 cm −1 , correlating with the surface OH groups in the HNTs’ lumen and the inner OH groups located between the tetrahedral and octahedral sheets, respectively 45 , 46 . Furthermore, SF peaks that belong to amid (I), amide (II), and amid (III) were observed in 1628 cm −1 , 1510 cm −1 , and 1226 cm −1 .…”

Halloysite-Based Magnetic Nanostructures for Diverse Applications: A Review

“…This means that the nanocomposite does not cause any significant damage to red blood cells, making it a suitable candidate for biomedical applications (Scheme 39). 161 Three-dimensional nanocomposite scaffolds were prepared using polycaprolactone-polyethylene glycol-polycaprolactone/ gelatin (PCEC/Gel) with the addition of biocompatible nanohydroxyapatite (nHA), Fe 3 O 4 NPs, and halloysite nanotubes (HNT) by the freeze-drying method. These scaffolds were tailored to possess the ideal physical, chemical, and biological characteristics for tissue regeneration and evaluated for their physical properties, cell viability, and osteoconductivity.…”

A novel nanocomposite containing zinc ferrite nanoparticles embedded in carboxymethylcellulose hydrogel plus carbon nitride nanosheets with multifunctional bioactivity

“…The remarkable characteristic attributed to hydrogels is the ability to absorb water or liquids with biological properties without changing their structures. 1–3 Hydrogels were first reported in 1960 by Wichterle and Lím. 4 The abovementioned characteristics of hydrogels have led to their widespread use in a variety of biomedical fields, including tissue regeneration, 5,6 contact lenses, 7 wound dressings, 8 expansion of stem cells, 9 tissue engineering, 10,11 drug delivery, 12 functional coatings, 13 or as antibacterial 14 and antimicrobial 15 materials.…”
