Preparation and application of galactomannan-based green hydrogels initiated by lignin-Ag NPs

Organic–inorganic composite hydrogels: compositions, properties, and applications in regenerative medicine

“…172 Min et al 173 introduced amino-functionalized BG NPs, and poly (ethylene glycol) diglycidyl ether (PEGDE) into genipin crosslinked glycol chitosan hydrogel to form a secondary crosslinked hybrid network via the high reactivity of the diepoxy groups in PEGDE toward amino and hydroxyl groups. Liu et al 103 utilized lignin-silver NPs to composite with 2-octenyl succinic anhydride modified galactomannan hydrogel, involving reactions related to vinyl groups on galactomannan and quinone/catechol redox reversible transition.…”

“…As well, metallic nanoparticles with excellent electrical conductivity are widely used as conductive-enhancing fillers or dopants. 27,28 Liu et al 29 demonstrated the successful preparation of Ag nanoparticles (Ag NPs) in a hydrogel sensor, showing good mechanical properties (stress = 42 kPa, strain = 618%) and electrical conductivity (GF = 2.72). Nevertheless, there is a propensity for conductive particles to aggregate, which may weaken the mechanical strength and reduce the conductivity.…”
