Summary: In this study, a composite material containing zein and C-phycocyanin (ZCPhy 20) was successfully developed using electrospinning. The addition of phycocyanin resulted in larger diameter tubular fibers. Simulation experiments provided insights into the structural changes of proteins in acidic conditions and under applied voltage. The results confirmed protein denaturation and unfolding through a helix-to-coil transition. Further characterization experiments, including FTIR, Raman, XRD, and CD, showed consistent findings with the simulations, confirming the structural changes of the proteins after electrospinning. Additionally, the thermostable ZCPhy 20, obtained from TGA thermograms, exhibited significant antioxidant activity in both native and fibrous forms, as evidenced by the DPPH assay. Lastly, ZCPhy 20 demonstrated remarkable antibacterial and anti-cancer activity against HT-29 cells. These findings highlight the potential of ZCPhy 20 composite as an edible film with medical and non-medical applications.

Summary: This paper presents a method of manufacturing nanofiber yarns (NFY) using a simplified dry electrospinning system to produce self-assembling functional NFY capable of conducting electrical charge. By enhancing the conductivity and allowing fibers to align and grow in a twisted pattern, the longer the electrospinning continues, the longer and more uniformly twisted the NFY becomes. Additionally, this process reduces the electric field required for NFY production.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
