Flow Behavior and Drug Release Study of Injectable Pluronic F-127 Hydrogels containing Bioactive Glass and Carbon-Based Nanopowders

Novel antibacterial hydrogels based on gelatin/polyvinyl-alcohol and graphene oxide/silver nanoconjugates: formulation, characterization, and preliminary biocompatibility evaluation

“…The volume-weighted average diameter (d 43 ) was regarded as the mean diameter for all measurements. Gelatin was used as reference material, and the obscuration was set between 5 and 15% using water as a dispersant at 1300 RPM constant agitation [ 65 , 66 , 67 ].…”

Two-Step Thermoresponsive Ultrafiltration Membranes from Polymerization of Lyotropic Liquid Crystals

“…44 Before starting the discussion regarding this behavior in the LLC nanostructure, it is required to have an understanding about the LCST behavior of F127, which is observed as a sol− gel transition in aqueous media. 45 When the temperature rises to 25−37 °C, hydrophobicity of the PPO block increases, which results in aggregation of PPO chains and thus formation of the core of the micelles. In addition, PEO chains form a packed interconnected micelle corona, resulting in the formation of a gel.…”

“…This transition can be reversed by cooling down the formed gel. 45 Therefore, the PPO block is mainly responsible for the LCST behavior of F127 around 25−37 °C. In the reported studies on LLCs and polyLLCs created by Pluronic surfactants, the PPO block is suggested to be oriented toward the apolar domain.…”

Mesoporous Properties of Bioactive Glass Synthesized by Spray Pyrolysis with Various Polyethylene Glycol and Acid Additions

“…BG is a surface-active bioceramics, with non-toxicity, non-inflammatory, and osteogenic potential that can firmly bond with bone and induce hard and soft tissue regeneration [ 3 , 4 , 5 ]. BG is also safe and stable in the human body [ 6 , 7 ]; thereby, BG is widely used in clinical application in dentistry, orthopedics, and biomedical engineering, such as bone replacement, tooth repair, and drug-carrying materials [ 8 , 9 , 10 , 11 ].…”

“…Scholars introduced the idea of adding polymer surfactant, such as P-123 (EO 20 PO 70 EO 20 ) or F-127(EO 106 PO 70 EO 106 ), as a structural template to fabricate mesoporous bioactive glass (MBG) to increase the specific surface area of BG effectively [ 18 , 19 , 20 ]. MBG possessing hollow, porous structure, and high specific surface area not only exhibits excellent bioactivities but also serves as drugs or bioactive molecular carriers [ 11 , 21 , 22 ]. Nevertheless, both P-123 and F-127 have non-single composition and are copolymers of PPO-PEO [PEO, poly(ethylene oxide); PPO, poly(propylene oxide)] contains lipophilic and hydrophilic polymers, thus, it is difficult conducting a subtle examination of the surfactants’ physical properties [ 19 , 20 ].…”
