AI Article Synopsis
- Imogolite is a clay mineral found in volcanic ash soils, which can be combined with DNA to create innovative hybrid hydrogels.
- These hydrogels are formed through strong interactions between imogolite's aluminol groups and DNA's phosphate groups, with varying feed ratios affecting their properties.
- The hybrid gels exhibit different physical structures in dispersion (fibrous imogolite) vs. gel state (3D network), with the optimal DNA content achieved at an equivalent molar ratio of imogolite and DNA.
Article Abstract
Imogolite is one of the clay minerals contained in volcanic ash soils. The novel hybrid hydrogels were prepared from imogolite nanofibers and DNA by utilizing strong interaction between the aluminol groups on imogolite surface and phosphate groups of DNA. The hybrid hydrogels of imogolite and DNA were prepared in various feed ratios, and their physicochemical properties and molecular aggregation states were investigated in both dispersion and gel states. The maximum DNA content in the hybrid gels was shown in equivalent molar ratio of imogolite and DNA. The physical properties of the hybrid gels were changed by varying DNA blend ratios. In the dispersion state, the hybrid gels showed a fibrous structure of imogolite, whereas a continuous network structure was observed in pure imogolite, indicating that the hybrid with DNA enhanced the dispersion of imogolite. In the gel state, DNA and imogolite nanofibers formed a 3D network structure.

Bentonite clay nanoparticles assume a pivotal role in 3D bioprinting and tissue engineering by augmenting the mechanical rigidity and biological efficacy of hydrogels. In this investigation, Span80 was employed as a surfactant to facilitate the synthesis of uniformly sized bentonite nanoparticles measuring approximately 700 nm in diameter. The resultant hybrid hydrogel displaced a marked increase in compressive modulus, achieving a peak value of 17.

Hybrid hydrogels are promising for wound dressing, tissue engineering, and drug delivery due to their exceptional biocompatibility and mechanical stability. This study synthesized hybrid hydrogels for photodynamic therapy using electron beam-initiated polymerization with varying PEGDA/gelatin ratios and irradiation doses to evaluate their effectiveness as uptake and release systems for five photosensitizers. Toluidine blue, O (TBO); methylene blue (MB); eosin, Y; indocyanine, green; and sodium meso-tetraphenylporphine-4,4',4″,4‴-tetrasulfonate were studied for their uptake and release dynamics in relation to their structural properties and the hydrogels' composition.

Article Synopsis
- The study introduces a neo-Hookean elasticity theory for hybrid mechano-active hydrogels by incorporating motor proteins into polymer structures, leading to materials that actively soften due to adjustable chain overlaps.
- The focus is on polyacrylamide hydrogels enhanced with the bacterial protein FtsZ, using a multiscale model that combines microscopic rubber mesh theory, mesoscopic scaling concepts, and phase transition formalism to explain the observed active softening.
- This research provides valuable insights for designing and controlling complex active hydrogels, potentially advancing applications in technology and biomedicine.
