Andrew Lee, Andrew Hudson, Dan Shiwarski, Josh Tashman, TJ Hinton, Sai Yerneni, Jaci Bliley, Phil Campbell, and Adam Feinberg are co-authors on our recent article in Science entitled “3D bioprinting of collagen to rebuild components of the human heart.” In the article we report our second-generation of FRESH 3D bioprinting, using it to print collagen and cells in to functional tissues and components of the human heart, from vascular-like networks to small beating ventricles.
“Patterning on Topography for Generation of Cell Culture Substrates with Independent Nanoscale Control of Chemical and Topographical Extracellular Matrix Cues”
Emily Sevcik, John Szymanksi and Quentin Jallerat are co-authors on our recent article in Current Protocols in Cell Biology entitled “Patterning on Topography for Generation of Cell Culture Substrates with Independent Nanoscale Control of Chemical and Topographical Extracellular Matrix Cues.” In the article we provide detailed methods on how to perform our Patterning on Topography (PoT) technology to independently pattern extracellular matrix proteins on topographically complex surfaces for studying cell-material interactions.
“Stretch-dependent changes in molecular conformation in fibronectin nanofibers”
John Szymanksi, Emily Sevcik and Kairui Zhang are co-authors on our recent article in Biomaterials Science entitled “Stretch-dependent changes in molecular conformation in fibronectin nanofibers.” This article is part of the Biomaterials Science Emerging Investigators 2017 issue of the journal. In the article we used AFM imaging of fibronectin nanofibers over a wide range of deformations to understand how reversible molecular unfolding contributes to the mechanical properties of extracellular matrix proteins.

“Measuring the Poisson’s Ratio of Fibronectin Using Engineered Nanofibers”
John Szymanksi and Kairui Zhang are co-authors on our recent article in Scientific Reports entitled “Measuring the Poisson’s Ratio of Fibronectin Using Engineered Nanofibers.” This article used AFM imaging of fibronection nanofibers over a wide range of deformations to show that volume is conserved, thus behaving as an elastic material with a Poisson’s ratio of ~0.5.

“3D Printing PDMS Elastomer in a Hydrophilic Support Bath via Freeform Reversible Embedding”
TJ Hinton, Andrew Hudson, Kira Pusch and Andrew Lee are co-authors on our recent article in ACS Biomaterials Science & Engineering entitled “3D Printing PDMS Elastomer in a Hydrophilic Support Bath via Freeform Reversible Embedding.” This article describes a new technique termed Freeform Reversible Embedding (FRE) to 3D print polydimethysiloxane (PDMS) elastomer such as Sylgard 184 in complex 3D structures within a hydrophilic Carbopol support. Unique is the ability to 3D print PDMS that takes hours to days to cure, demonstrating the capability to 3D print fluidic materials and decoupling the gelation and curing of the polymer from its ability to be 3D printed.
