Redox-responsive phosphonate-functionalized poly(β-amino ester) gels and cryogels

Acid mine drainage pollution remediation using hybrid chelating ion-exchange/HZrO2 nanocomposite adsorbents

“…The two P-O stretching phosphonate groups of the host and its hybrid were observed at 1100 and 950 cm −1 . In another study, in different media, the phosphonate P-O stretching at 1016 and 966 cm −1 has been reported [5]. The peaks at about 745.7 and 524.3 cm −1 are attributed to the Zr-O bond of the dispersed hydrated Zr oxide nanoparticles for the hybrid adsorbents [27].…”

Nanoporous Metal Phosphonate Hybrid Materials as a Novel Platform for Emerging Applications: A Critical Review

“…The construction of novel porous materials with well-designed network topologies is one of the most challenging directions in various research fields owing to the great potential of these materials in the booming bio-applications including drug delivery, [192][193][194][195][196] and bioceramics. [197,198] Excitingly, the impressive ability of porous metal phosphonate hybrid materials with predefined functionality and well-defined porosity as well as valuable biocompatibility make them stand out from all kinds of porous materials, showing the huge promise to be a novel category of biomaterials. In the following subsections, the applications of porous metal phosphonates in biomaterials are discussed, including drug delivery, bioceramics, and biofuels.…”

“…Although metal phosphonates have exhibited excellent performances in the treatment of bone-related conditions, they can also be directly explored as promising bioceramic materials for repairing and replacing the damaged portion of the human skeleton. [197,198] Porous metal phosphates or phosphonates can be used as excellent bioactive glasses for the ingrowth of soft and hard tissues and afford the necessary toughness and elasticity of bones. [3,10] One of the most widely investigated materials in this context is calcium orthophosphate-based materials, [10] which can function as good bioceramic for the replacement of bones, ligaments, or teeth as well as for the regeneration of bone tissues.…”

“…These findings revealed the good promises of metal phosphates and phosphonates for future application in bioceramic materials. [197][198][199]…”

Structure-property relationships of novel phosphonate-functionalized networks and gels of poly(β-amino esters)

“…Incorporation of phosphorous containing groups to polymeric networks extends their application areas due to their strong interaction with hydroxyapatite-based tissue [36][37][38][39] and enhances their cell adhesion, [40][41][42][43][44][45] swelling and thermal properties. Recently, we have reported the effect of the phosphonate and bisphosphonate group on PBAE network properties [46][47][48]. Phosphonate-functionalized PBAE macromers were synthesized through reaction of various diacrylates and a primary phosphonate-functionalized amine (diethyl 2-aminoethylphosphonate).…”
