Resin-based dental materials containing 3-aminopropyltriethoxysilane modified halloysite-clay nanotubes for extended drug delivery

High‐density polyethylene/attapulgite (ATP) nanocomposites: Effect of the organophilization of ATP on the structural, mechanical, and thermal properties

“…These peaks refer to the 2Al 2− OH vibrational mode in the octahedron 31,35,36 . The peak in 3580 cm −1 regarding AlMgOH or AlFe 3+ OH stretch 30,33,34 . The peak in 1655 cm −1 refer to zeolite water deformation, 30,34 the peak in 1195 cm −1 regarding SiOSi stretch 32,34 and 985 cm −1 refer SiOH stretch 20,37…”

“…For ATPr it is possible to observe in the regions between 3616 cm À1 the main characteristic peaks of hydroxyl vibrations linked to metal present (2M 2 -OH stretch where M = Al) [32][33][34] and 3266 cm À1 (zeolite water stretch [Al Mg OH] or [Fe Mg OH]). 32,34 These peaks refer to the 2Al 2À OH vibrational mode in the octahedron. 31,35,36 The peak in 3580 cm À1 regarding Al Mg OH or Al Fe 3+-OH stretch.…”

“…31,35,36 The peak in 3580 cm À1 regarding Al Mg OH or Al Fe 3+-OH stretch. 30,33,34 The peak in 1655 cm À1 refer to zeolite water deformation, 30,34 the peak in 1195 cm À1 regarding Si O Si stretch 32,34 and 985 cm À1 refer Si OH stretch. 20,37 For ATPo, the characteristic peaks appear at 2920 and 2851 cm À1 due to the elongation vibration of the C H bond, indicating the presence of the quaternary salt.…”

PEGylated green halloysite/spinel ferrite nanocomposites for pH sensitive delivery of dexamethasone: A potential pulmonary drug delivery treatment option for COVID-19

“…The external adsorption site (specific surface area) of Hal can be modified by treatment with HCl for effective drug incorporation and influence the release rate of antioxidant such as curcumin ( de Abreu Pereira et al, 2021 ). Halloysite with high tubular surface area, biocompatibility, functionable aluminol and siloxane moieties has been used as a controlled drug release carriers for cancer ( Mo et al, 2021 ), tissue engineering ( Gkouma et al, 2021 ), diabetes mellitus ( Massaro et al, 2018 ), dental ( Karczewski et al, 2021 ), herbicide ( Tan et al, 2015 ), etc. Gold nanoclusters supported on silane modified Hal has been described as an effective nanocomposite inducing non-toxic effect at desired concentration range (25–50 μg/ml) suitable for tumor imaging and cancer therapy ( Gorbachevskii et al, 2021 ).…”

Dental resin composites: A review on materials to product realizations

“…employed in recent years to synthesize dental materials as shown in Figure4. HNTs are the new type of attractive additive especially in dental materials research because of their unique physical and chemical characteristics, low cost in manufacturing, and good biocompatibility compared to other types of synthesized nanotubes[102,[127][128][129].…”
