3D Printed Metal Nanoparticle Composites for Tissue Regeneration

Thermoplastics are inexpensive, easy to process, chemically stable, lightweight, and flexible materials making them attractive for use in 3D printing applications. Customization potential, freedom of design, print fidelity, and the ability to manufacture complex structures with new functionalities are key advantaged of 3D printing. Metal nanoparticles (MNPs) are also inexpensive and come with a range of biological properties. Metal alloy thermoplastic composed filaments are cheap and, with new extruder technology, are easy to fabricate, offering significant increases in flexibility, mechanical strength, antimicrobial properties, and tissue regenerative properties, depending on the metal nanoparticle employed. This symposium thus focuses on 3D printing of MNP-reinforced materials for tissue regeneration.

Antimicrobial and Antibiofilm Biomaterials Strategies

Treatment of microbial infections is complicated by rising antibiotic resistance and the inherent difficulty of treating biofilm-associated infections. In both scenarios, many current FDA approved antimicrobial drugs are ineffective, leading to a significant health and economic burden. Compounding these issues is a lack of development of new antimicrobial drug classes limiting the pipeline of available therapeutics. Advances in antimicrobial biomaterial therapies have the potential to improve outcomes for bacterial, fungal, viral, and biofilm-associated infections. Innovations in biomaterials are critically needed in the face of the COVID-19 pandemic, both for treatments of the SARS-CoV-2 virus, and also for effective treatment of the severe bacterial and fungal co-infections that have been reported. This session will cover biomaterials approaches to treat bacterial, fungal, and viral infections, including the prevention and eradication of biofilms. Strategies discussed may include antimicrobial surface modifications, device coatings, drug delivery, and immune engineering approaches.

Anti-Thrombogenic Coatings/Biomaterials for Vascular Applications

Thrombosis and intimal hyperplasia have been the major complications of bypass graft surgery. Autologous vessels are the gold standard for bypass graft surgeries. However, due to unavailability of healthy autologous arteries, synthetic polymers have been widely employed for the fabrication of vascular grafts. Synthetic polymers are associated with high rates of thrombosis and intimal hyperplasia especially small diameter vessels and low flow blood velocity zones. Hence, there has been extensive research performed on coatings and surface modification strategies to improve the performance of endovascular devices and grafts. This symposium will highlight some of the recent in vitro and in vivo research and advancements in surface modification techniques/characterization and biomaterial coatings that can prevent the events and incidence of thrombosis and intimal hyperplasia. This session will also include review of abstracts on next generation biomaterials that have the potential to promote endothelialization and prevent inflammation.

Commercialization and Regulatory Paths of Non-Fusion Spine Technologies

Spinal fusion remains the most common spine procedure for the treatment of a variety of degenerative spinal conditions, and though the number of procedures and associated costs increase each year, there is a little consensus on its efficacy. In most cases, the pathway towards spinal fusion is based on unsuccessful conservative therapies and the lack of reasonable therapeutic alternatives. This lack of alternatives often leads surgeons to accept potential risks, side-effects and complications to help patients get rid of their symptoms. Thus, there is a need to explore alternative technologies targeting commercialization and regulatory approval. This session aims to highlight the translation, development, and commercialization of such novel spinal technologies, and how they compare and contrast to the most recent development not only in fusion, but also conservative care options. Works with late-stage pre-clinical developments, clinical feasibility results, and those that feature insight from diverse regulatory bodies around the globe from a will be given focus.

Responsive Nanomaterials for Theranostics and Tissue Engineering

The aim of this symposium is to showcase the next generation of nano-enabled molecular diagnostic and therapeutic systems and their use in precision nanomedicine. Over the past few years, there have been substantial advances in the development of functional nanomaterials engineered to systematically change their properties in response to endo/exogeneous stimuli. This behavior enables the use of such responsive nanosystems as therapeutic vectors with controlled release and systemic distribution, as probes for minimally invasive imaging, or as scaffolding materials for in vitro tissues. Efforts towards increasing the sensitivity and specificity of stimuli-responsive nanomaterials continue to emerge, motivating the development of novel systems and the adaptation of well-established responsive materials to novel applications. The proposed symposium will bring attention to the aforementioned efforts, focusing on targeted theranostics using responsive nanomaterials. In particular, the symposium will highlight nanoparticle-biomolecule conjugates that are integrated with functional systems and used as sensing or transducing elements for diagnostic and on-demand therapeutic interventions.

This session will focus on the development and use of such materials for applications including, but not limited to, cancer, and infectious, orthopedic, ophthalmic, and autoimmune diseases. Researchers from all sectors (academia, clinical, industry, government), are encouraged to submit abstracts.

State-of-the-Art in Sterilization of Biomaterials: Existing Modalities and Novel Techniques Under Development

With the rapid growth of technologies in the fields of regenerative medicine, biologics, and biopharma, the ability to sterilize complex biomaterials has become an important consideration. The minimal compatibility of current sterilization modalities (e.g., steam, e-beam, gamma irradiation, ethylene oxide) has spawned an evolution of novel sterilization techniques showing promise as recognized by the US FDA Innovation Challenge to "Identify New Sterilization Methods and Technologies". Given the complexity of many medical devices, biologics and drugs, there is not likely to be a ‘one size, fits all’ platform for sterilization; thus, multiple new modalities and techniques will be needed, and paths to regulatory approval should be understood. This session aims to present the current challenges as well as existing and emerging sterilization solutions for complex biomaterials, biologics, and bioactives. Contributions focused on one or more of the following areas are of interest to this session: the state-of-the-art in sterilizing biomaterials, biologics, and bioactives; technical innovations; regulatory considerations; and paths to commercialization.

Natural, plant-based small molecules (e.g., phenolics, fatty acids) and other higher molecular weight natural derivatives (e.g., starches) provide a multitude of potential functionalities for biomaterial scaffolds, such as antimicrobial, anti-inflammatory, and antioxidant properties. These functional scaffolds could be developed for a broad range of applications, such as in wound healing, blood-contacting materials, and cancer, to improve outcomes while reducing risks associated with synthetic drugs. We invite abstracts on research that covers natural molecule incorporation into biomaterial scaffolds and characterization of their activity, safety, and functionality in vitro or in vivo.

Tissue Engineering (SIG)

Tissue Engineering SIG is a forum to exchange information, further knowledge, and promote greater awareness regarding all aspects of the use of biomaterials to engineering tissue substitutes or to promote tissue regeneration. Of primary interest and relevance to TE SIG is the use of appropriate materials (synthetic and natural) with cells (either native or from a donor source) and/or biological response modifiers (e.g., growth factors, cytokines and other recombinant products) to replace tissue and organ functions. Particular emphasis is placed on the development of materials to better incorporate, protect, and deliver both the cells and biological response modifiers to help promote the healing and regenerative processes. The group is committed to forging interactions among basic scientists, applied scientists, engineers, clinicians, industrial members, professional societies in related fields, and regulatory groups in its efforts to expand and effectively utilize the shared knowledge base in this multidisciplinary field.

Tissue Engineering Inspired Organ Models For the Testing of the Toxicity of Chemicals

Enabling tissue engineering technologies, including 3d- and bio-printing, nanotechnology and cell manipulation, combined with microfluidics, open the way to a precise recapitulation of the complex human physiology in vitro. In this scenario, the symposium aims at reviewing the most promising approaches towards the realization of new bioinspired devices able to predict the toxicity of chemicals to humans, envisaging pathways towards their adoption in regulatory processes with a consequent reduction of animal experiments.
In this context the symposium aims at collecting, not exclusively, contribution of the scientific community in areas such as those of
- engineering tissues and organs for 3D in vitro models
- cells, tissues and organs on a chip
- human on a chip
- spheroids and organoids
- approaches towards the biomimetic recapitulation of biological and pathological cell environments
- in silico models
- regulatory frameworks
- omics approaches
