Special Issue Information

Dear Colleagues,

Advanced polymers for biological applications represent foundational scaffold components in tissue engineering, regenerative medicine, and other medical fields. Tailoring the advanced properties offered by the polymer’s compositions, structures, and functionalities through biomanufacturing techniques to interface living matter has sparked remarkable interdisciplinary research interest. These techniques include, but are not limited to, 3D printing, electrospinning, microfluidics, injectables, patterning, and casting. Biomanufacturing techniques combine biomechanical modelling, engineering reformation, material functionalisation, and cell biology development to construct innovative results that could benefit clinical applications in the future.

Given the thriving nature of biopolymers in bioengineering applications, this Special Issue aims to showcase the state-of-the-art advances in polymer-related medical applications such as synthetic cell and tissue, coacervate, drug delivery, biomedical sensing and treatment, bio-inspired devices, biological interfaces, organoids, induced pluripotent stem cells, etc. We look forward to your submission of intriguing results that will enrich and inspire this interdisciplinary field.

In trauma and surgery, efficient hemorrhage control is crucial to avert fatal blood loss and increase the likelihood of survival. There is a significant demand for novel biomaterials capable of promptly and effectively managing bleeding. This study aimed to develop flexible biocomposite fibrous scaffolds with an electrospinning technique using silk fibroin (SF) and indocyanine green (ICG). The FDA-approved ICG dye has unique photothermal properties. The water permeability, degradability, and biocompatibility of Bombyx mori cocoon-derived SF make it promising for biomedical applications. While as-spun SF-ICG fibers were dissolvable in water, ethanol vapor treatment (EVT) effectively induced secondary structural changes to promote β-sheet formation. This resulted in significantly improved aqueous stability and mechanical strength of the fibers, thereby increasing their fluid uptake capability. The enhanced SF-ICG interaction effectively prevented ICG leaching from the composite fibers, enabling them to generate heat under NIR irradiation due to ICG’s photothermal properties. Our results showed that an SF-ICG 0.4% fibrous matrix can uptake 473% water. When water was replaced by bovine blood, a 25 s NIR irradiation induced complete blood coagulation. However, pure silk did not have the same effect. Additionally, NIR irradiation of the SF-ICG fibers successfully stopped the flow of blood in an in vitro model that mimicked a damaged blood vessel. This novel breakthrough offers a biotextile platform poised to enhance patient outcomes across various medical scenarios, representing a significant milestone in functional biomaterials. Full article
