In recent years, we have witnessed remarkable progress in the development of biomaterials with enhanced biocompatibility, improved mechanical properties, and bioactivity.These materials serve as the building blocks for a wide range of applications, including tissue scaffolds, drug delivery systems, and implantable devices.Breakthroughs in nanotechnology, 3D printing, and material science have enabled the creation of intricately designed structures at the micro-and nanoscale, mimicking the complexity of native tissues and organs [3].
Biodevices, such as biosensors, wearable health monitors, and implantable medical devices, have also seen significant advancements, revolutionizing disease diagnosis, monitoring, and treatment.These devices offer real-time, non-invasive insights into patients' health status, empowering individuals to take proactive measures to manage their wellbeing.Furthermore, integrating biocompatible materials and smart technologies has paved the way for the development of implantable biodevices capable of interfacing with the body's natural processes [4].
Tissue engineering holds immense promise for addressing the growing demand for organ transplantation and regenerative therapies.By combining cells, biomaterials, and biochemical cues, researchers are striving to create functional tissues and organs in the laboratory for transplantation and disease modeling.While the field has made significant strides in generating simple tissues like skin and cartilage, challenges remain in engineering more complex organs with intricate vascular networks and heterogeneous cell populations [5].
Moreover, biocompatibility, long-term stability, and immune responses remain significant concerns for implanted devices and engineered tissues.Additionally, the scalability and cost-effectiveness of these technologies pose barriers to their widespread adoption in clinical practice.Moreover, ethical considerations surrounding using human-derived cells and tissues in research and transplantation continue to spark debate and raise important questions about consent, equity, and social justice [6].
This editorial summarizes the published studies of the Special Issue on "Biomaterials, Biodevices and Tissue Engineering," which includes six publications that are discussed as follows: Solis-Rios et al. [7] present a pioneering application of artificial neural networks (ANNs) to predict the diameter of polyethylene nanofibers, thereby streamlining the parameter adjustment process in electrospinning.Leveraging a dataset of 105 records sourced from the literature, the ANN model demonstrates promising accuracy in predicting nanofiber diameter, with validation against laboratory measurements yielding an average error of 2.29%.The study highlights the potential of machine learning techniques to revolutionize nanofiber production by offering rapid and reliable predictions while emphasizing the need for further validation and expansion of the dataset to ensure the robustness and generalizability of the model.Overall, this research represents a significant step forward in advancing efficiency and reducing costs in producing polyethylene nanofibers, with implications for a wide range of applications [7].
Laubach et al. [8] explores the potential of exopolysaccharides (EPSs) derived from the thermophilic bacterium Geobacillus sp.strain WSUCF1, synthesized using cost-effective lignocellulosic biomass, as a foundation for creating 5-fluorouracil (5-FU)-encapsulated films for topical drug delivery.5-FU, a widely used chemotherapeutic agent, was incorporated into the EPS-based film formulation via a simple self-forming method.The study demonstrates the effectiveness of the 5% 5-FU film against A375 human malignant melanoma cells, with cell viability decreasing to 12% after six hours of treatment.Additionally, the drug release profile exhibited an initial burst release followed by an extended and sustained release of 5-FU.These findings highlight the potential of thermophilic EPSs from lignocellulosic biomass as a versatile platform for delivering chemotherapy drugs and expanding the scope of extremophilic EPS applications [8].
Ashkani et al.
