Meeting ID: 933 1559 4357
The mechanical behavior of biological materials (often small and ultrasoft) is based on complex structure-function relationships. These relationships are a function of underlying substrate material, chemistry, and geometry. With the advent of 3D bioprinting, scaffold design and materials properties have entered an unexplored territory that lacks a “standard materials” properties database. Traditionally, nanoindentation-based techniques have been used to characterize the mechanical properties of complex structures and biological tissues. Although nanoindentation is a very useful method, its knowledge and experience are primarily derived from conventional materials like metals, ceramics, and polymers. Nanoindentation of ultrasoft and small-scale materials is full of challenges and requires a very approach for tissue engineering application. This talk will address how to overcome those challenges. Several examples related to the mechanical behavior of 3D printed polymer structures and cardiac tissued will be presented. An approach to evaluating multi- (meso/macro to micro) scale properties of soft materials will be presented, which could create a database for the modeling.
