Special Issue Information

Dear Colleagues,

Medical applications have historically driven biomaterials’ development in drug delivery and tissue scaffolding in search of biocompatibility and enhanced human health; however, certain bio-composites’ natural biodegradability, adaptability to environmental parameters, and capacity to encapsulate active molecules for sensing and response have sparked new research in non-medical applications. This is particularly the case in the context of sustainability and the creation of biodegradable or environmentally friendly materials with unprecedented functions—bridging optical, mechanical, biological, and chemical properties.

This Special Issue discusses biomaterials and bio-composites at the center of biomedical innovation, but they are increasingly informing and interfacing with other fields such as sustainable apparel development, bio-based consumer products, eco-attuned building construction systems, or blend discovery via artificial intelligence. This multi-disciplinary interplay is due to both challenges and opportunities in biomaterials and bio-composites’ multifunctional structures, property variability, new processing techniques, responses to environmental factors, and programmable durability.

Recommended Topics

  • Design and development of multifunctional bio-composites.
  • Interdisciplinary research in biomaterials and bio-composites.
  • Artificial intelligence applied to bio-composite property prediction.
  • Applications of bio-composites beyond medical fields.

Microorganisms metabolising low-value carbon sources can produce a diverse range of bio-based and biodegradable materials compatible with circular economy principles. One such material is bacterial cellulose (BC), which can be obtained in high purity through the fermentation of sweetened tea by a Symbiotic Culture of Bacteria and Yeast (SCOBY). In recent years, there has been a growing research interest in SCOBYs as a promising solution for sustainable material design. In this work, we have explored a novel method to grow SCOBYs vertically using a waste-based scaffold system. Waste sheep wool and cotton fabric were soaked in a SCOBY infusion to serve as scaffolds, carrying the infusion and facilitating vertical growth through capillary forces. Remarkably, vertical membrane growth up to 5 cm above the liquid–air interface (LAI) was observed after just one week. Membranes with different microstructures were found in sheep wool and cotton, randomly oriented between the scaffold fibre, resulting in a high surface area. This study demonstrated that vertical growth in scaffolds is possible, proving the concept of a new method of growing composite materials with potential high-value applications in biomedicine, energy storage, or filtration.

While prior studies have explored developing mycelium paste for EAM of this material, this research streamlined the EAM workflow for preparing living, extrudable mycelium mixtures, involving alterations in the preparation sequence and adjustments in the admixture ratios. The resultant mycelium mixture was employed in a series of experiments to optimize the parameters of robotic EAM using Artificial Neural Networks. Next, a performance-based acoustic wall was designed informed by simulation in Pachyderm. Building upon previous research by authors, two adjacent panels with high complex geometric features were selected for fabrication, presenting a challenging test scenario, as conventional planar slicing introduces stair-stepping phenomena, while non-planar slicing introduces irregularities in layer height. To address these, a hybrid slicing strategy was used by integrating both slicing techniques. Next, an experimental framework was established to assess the influence of EAM toolpath planning factors on the acoustic properties of the designed acoustic panels. Lastly, two panels were fabricated using an ABB IRB 2400 robotic arm. The alignment of the toolpath planning factors and EAM parameters resulted in a uniform material deposition in the final fabricated panels. This study underscores the transformative capacity of robotic EAM and conformal toolpath planning, presenting the development of biodegradable building materials and advanced acoustic solutions.
