Color-tunable, self-healing albumin-based lanthanide luminescent hydrogels fabricated by reductant-triggered gelation

Research progress on albumin-based hydrogels: Properties, preparation methods, types and its application for antitumor-drug delivery and tissue engineering

“…For example, Seyed et al used ethanol to reduce the proportion of strongly bound FAs in BSA-based hydrogels by 52% and induced a maximum storage modulus of 5,000 Pa in BSA-based hydrogels ( Arabi et al, 2020 ). The excellent mechanical properties of albumin-based hydrogels are not only reflected in the high or low mechanical strength, but also in the rapid self-healing ( Wang J.-T. et al, 2022 ). Wang et al demonstrated through tensile and compression tests that the rapid self-healing properties of the BSA complex hydrogel constructed by themselves, which is able to meet the needs of some practical applications, such as wound healing dressings, tissue scaffold materials, beauty products and so on ( Ganesan and Choi, 2016 ; Kharaziha et al, 2021 ; Sun et al, 2021 ).…”

Bovine Serum Albumin/Polyvinyl Alcohol Double‐Network Hydrogel Containing ϵ‐Polylysine for Antibacterial Performance

“…As shown in Figure 2a, BSA hydrogel showed obvious redshift relative to BSA solution in the range of 500-600 cm À 1 , and BSA hydrogel showed characteristic peaks in the range of 2550-2590 cm À 1 , indicating that disulfide bonds of BSA were opened under the action of TCEP to form a large number of sulfhydryl group. [33,34] A large number of sulfhydryl cross-linked to form disulfide bonds and finally forming a hydrogel state. In Figure 2b, BP hydrogel showed obvious redshift relative to PVA at the position of 3000-3500 cm À 1 in the hydroxyl absorption band, indicating that PVA formed hydrogen bonds in the hydrogel network.…”

Optical Nonlinearity of Semiconducting Cd(II) Metallogel in the Femtosecond Regime with Two-, Three-, and Four-Photon Absorption

“…Supramolecular noncovalent forces, including hydrogen bonding, electrostatic interactions, donor–acceptor associations, hydrophobic effects, and π–π stacking, are essential in forming supramolecular gel materials directed by low-molecular weight gelators. − Supramolecular gels have gained prominence as versatile materials with a wide range of applications, including their use in chemosensors, lithography, electrochemical devices, catalysis, adsorption and removal of toxic dyes, optoelectronic devices featuring conjugated oligomers, polythiophenes, phthalocyanines, and tetrathiafulvalenes, drug delivery systems, cellular supports, tissue engineering, and antimicrobial and anticancer activities. − The incorporation of various transition and inner transition metal ions into the supramolecular gel network introduces a range of additional beneficial characteristics, including magnetic activity, optical activity, and semiconducting properties. − The current decade places significant emphasis on the design and synthesis of self-repairing metallogels, owing to their extended lifespan and multifaceted applications. − Recent research findings underscore the significance of factors such as the polarity of various chemical components, extensive π-electron delocalization, and intra- and intermolecular hydrogen bonding interactions, as pivotal contributors to the formation of self-healing metallogels and the emergence of their nonlinear optical properties. − It is legitimate to propose that self-healing behavior and optical nonlinearity are closely intertwined phenomena. In earlier research, we had explored the development of transparent metallogels using Cu­(II) metal salts and macromolecular gelators like BSA protein and investigated their nonlinear optical properties .…”
