Advanced Biomaterials for Biomedical Research

Expiration Date: September 9, 2028

Background

Biomedical research with engineered systems faces a fundamental challenge: traditional biomaterials fail to recapitulate the tissue complexity, heterogeneity, and dynamic evolution seen in vivo. Conventional scaffolds and hydrogels suffer from batch variability, rapid uncontrolled gelation, and growth factor content which confound mechanistic studies. Tissue-sourced extracellular matrices lack reproducibility essential for rigorous, controlled experimentation.

Recent advances in bioprinting, lithography, electrospinning, and synthetic biology enable design of materials better mimicking physiological conditions. However, gaps remain in modeling dynamic physical properties—stiffness gradients, viscoelasticity, stress relaxation, temporal evolution—characteristic of tissue microenvironments. Materials detecting or responding to tissue-specific changes (pH fluctuations, hypoxia, oxygen gradients, metabolite concentrations, cytokine profiles) would enable researchers to interrogate or model complex biological systems (e.g. early lesions and how tumors modify niches allowing invasion and metastasis).

For example, recent collaborative approaches between material scientists and cancer researchers have enabled understanding of the physical properties of cancer evolution. Materials scientists bring expertise designing responsive, tunable systems with controlled properties. Cancer biologists provide understanding of tumor biology, microenvironmental cues, and critical research questions. Together, these collaborations spur the development of biomaterial systems capable of responding dynamically to tumor-relevant stimuli, enabling new insights into cancer initiation, progression, metastasis, and therapeutic resistance that are challenging to study with current approaches. 

Purpose

This topic encourages the adaptation, integration and development of innovative, advanced biomaterials that enable material scientists and biomedical researchers to collaboratively address fundamental challenges in understanding biology. Advanced biomaterials or functionalized materials may 

• Enable dynamic physical properties
• Detect and respond to tissue specific changes
• Have robust and predictable biomaterial behavior
• Address issues of reproducibility in disease models.

Projects including multidisciplinary teams that foster convergence between materials scientists, physical scientists, bioengineers, and biomedical researchers are encouraged. Goals are to encompass creating novel alternative methods (NAMs) as accessible research tools and improving in vitro models to complement in vivo systems.
