“…What's more, the surface chemistry and permeability were reported to be versatile, controlled by importing functional groups through chemical methods, or by simply altering the interface energy in the process of membrane fabrication, resulting in flexibly tuned diffusion (Figure c,d) . The opened and closed conditions of the nanopores can also be selectively tuned by controlling their physical and chemical environments, such as pH and solvent . Hence they can also be utilized for drug delivery, and selectively loading and releasing small molecules …”

“…Since the unit cell size dominates the application areas, DG fi lms acquired from inorganic-organic systems, whose unit cell size is on the atomic scale, act exactly as molecular sieves. [ 16,77,121,122 ] Furthermore, they operate effectively in gas adsorption/desorption [ 186,187 ] with their high specifi c surface area. With the increase of unit cell size to several tens of nanometers, DG fi lms acquired from BCPs perform promisingly as ultrafi ltration (UF) membranes.…”

In search of optimal structures for functional materials fabrication, the gyroid (G) structure has emerged as a promising subject of widespread research due to its distinct symmetry, 3D interconnected networks, and inherent chiral helices. In the past two decades, researchers have made great progress fabricating G-structured functional materials (GSFMs) based on G templates discovered both in nature and in the lab. The GSFMs demonstrate extraordinary resonance when interacting with light and matter. The superior properties of GSFMs can be divided into two categories based on the dominant structural properties, namely, dramatic optical performances dominated by short-range symmetry and well-defined texture, and effective matter transport due to long-range 3D interconnections and high integrity. In this review, G templates suitable for fabrication of GSFMs are summarized and classified. State-of-the-art optical applications of GSFMs, including photonic bandgap materials, chiral devices, plasmonic materials, and matamaterials, are systematically discussed. Applications of GSFMs involved in effective electron transport and mass transport, including electronic devices, ultrafiltration, and catalysis, are highlighted. Existing challenges that may hinder the final application of GSFMS together with possible solutions are also presented.

“…13 Nanoporous materials have been widely applied as biomaterials for drug loading and releasing, regenerative medicine, etc owing to the unique characteristics including their uniform and tunable pore size distribution, high pore volume and large specific surface area. 14 Compared with the nonporous bioactive glass, the nanoporous bioactive glass possesses higher bioactivity due to its high pore volume and large surface area, thus could accelerate the deposition kinetics of apatite minimization, thereby improving the bioactivity and biocompatibility of the materials. 15 Therefore, as a new class of bioactive material, the nanoporous bioactive glass has a great potential for bone regeneration applications.…”

IntroductionIt is predicted that with increased life expectancy in the whole world, there will be a greater demand for synthetic biomedical materials to repair or regenerate lost, injured or diseased tissues. Natural polymers, as biomedical materials, have been widely applied in the field of regenerative medicine.Materials and methodsBy incorporation of nanoporous diopside bioglass (nDPB) into glia-din (GL) matrix, macro–nanoporous scaffolds of nDPB/GL composites (DGC) were fabricated by method of solution compressing and particles leaching.ResultsThe results revealed that the DGC scaffolds possessed well-interconnected macropores of 200–500 μm and nanopores of 4 nm, and the porosity and degradability of DGC scaffolds remarkably increased with the increase in nDPB content. In addition, in vitro cell experiments revealed that the adhesion and growth of MC3T3-E1 cells on DGC scaffolds were significantly promoted, which depended on nDPB content. Moreover, the results of histological evaluations confirmed that the osteogenic properties and degradability of DGC scaffolds in vivo significantly improved, which were nDPB content dependent. Furthermore, the results of immunohistochemical analysis demonstrated that, with the increase in nDPB content, the type I collagen expression in DGC scaffolds in vivo obviously enhanced, indicating excellent osteogenesis.Discussion and conclusionThe results demonstrated that the DGC scaffolds containing 30 wt% nDPB (30nDGC) exhibited good biocompatibility and new bone formation ability, which might have a great potential for applications in bone regeneration.
