Symmetrically substituted hexakis(alkoxy)triphenylene (HAT) derivatives were assembled into single molecular thick 2D nanosheets, which stacked further to give multilayered nanofibers through a convenient solution process. Detailed information on molecular arrangement was unraveled by various imaging techniques and diffraction studies.

The combining of therapeutic agents with electrospun nanofibers boosts their regeneration potential; therefore, Researchers have increasingly turned towards the development of electrospun nanofiber scaffolds to encapsulate or surface-adsorb biological payloads, such as cytokines, exosomes, peptides, nucleic acids, and enzymes. Due to their high surface-to-volume ratio, ease of manufacturing, and drug-loading capacity, electrospun nanofibers are hopeful in tissue engineering and scaffold fabrication. Electrospun multilayer scaffolds offer a promising construction for preserving the integrity and bioactivity of therapeutic factors while permitting the controlled and prolonged release of biomolecules into the environment.

Here, hybrid stimuli-responsive (exhibiting pyroelectricity and piezoelectricity) porous cryogels are engineered by embedding tourmaline nanoparticles (TNs) in a cellulose nanofiber (CNF) skeleton to generate high-performance CNF-TN-based airborne particulate matter (PM) filters. First, single-layer hybrid cryogels with varying TN contents (0-5% w v) are assembled, and the design principles for multilayered filters are established based on a novel sequential pre-freezing and freeze-drying technique. As observed, the embedded TNs transformed the CNF network into a more homogeneous, isotropic, and firm structure, thus improving the structural integrity and thermal stability of the assembled cryogels while maintaining their ultrahigh porosity and low density.

A promising approach for wound treatment is using multilayer wound dressings that offer multifunctional properties. In this study, a bilayered electrospun/hydrogel gelatin-based scaffold integrated with honey and curcumin was developed to treat wounds under an in vivo study. The first layer consisted of an enzymatic cross-linked gelatin hydrogel containing honey and curcumin, which gelatin/PCL nanofibers reinforced.

One of the unavoidable issues with the bio-scaffolding process is the collapse of the visually appealing external three-dimensional (3D) sponge-like structure and the internal porous and multilayered morphology of a gas-foamed nanofibrous scaffold. Herein, a gas-foamed polycaprolactone/cellulose (g-PCL/CL) nanofibers scaffold is first prepared by electrospinning PCL/cellulose acetate, followed by deacetylation and then Sodium borohydride-assisted gas-foaming technique. The deformed 3D architecture of g-PCL/CL nanofiber is finally reconstructed by mixing it with chitosan (CS) solution and molding.
