We engineered functional cardiac patches by seeding neonatal rat cardiomyocytes onto carbon nanotube (CNT)-incorporated photo-cross-linkable gelatin methacrylate (GelMA) hydrogels. The resulting cardiac constructs showed excellent mechanical integrity and advanced electrophysiological functions. Specifically, myocardial tissues cultured on 50 μm thick(More)
BACKGROUND Potential routes of nanomaterial exposure include inhalation, dermal contact, and ingestion. Toxicology of inhalation of ultra-fine particles has been extensively studied; however, risks of nanomaterial exposure via ingestion are currently almost unknown. Using enterocyte-like Caco-2 cells as a small intestine epithelial model, the possible(More)

The objective of this study was to develop an injectable and biocompatible hydrogel which can efficiently deliver a nanocomplex of graphene oxide (GO) and vascular endothelial growth factor-165 (VEGF) pro-angiogenic gene for myocardial therapy. For the study, an efficient nonviral gene delivery system using polyethylenimine (PEI) functionalized GO(More)
Incorporating graphene oxide inside GelMA hydrogels enhances their mechanical properties and reduces UV-induced cell damage while preserving their favorable characteristics for 3D cell encapsulation. NIH-3T3 fibroblasts encapsulated in GO-GelMA microgels demonstrate excellent cellular viability, proliferation, spreading, and alignment. GO reinforcement(More)
Current methods in treating chronic wounds have had limited success in large part due to the open loop nature of the treatment. We have created a localized 3D-printed smart wound dressing platform that will allow for real-time data acquisition of oxygen concentration, which is an important indicator of wound healing. This will serve as the first leg of a(More)
As our population ages, there is a greater need for a suitable supply of engineered tissues to address a range of debilitating ailments. Stem cell based therapies are envisioned to meet this emerging need. Despite significant progress in controlling stem cell differentiation, it is still difficult to engineer human tissue constructs for transplantation.(More)
We present a hybrid approach that combines top-down fabrication with bottom-up directed assembly for making single-walled carbon nanotube (SWNT) based three-dimensional interconnects. The SWNTs are assembled using dielectrophoresis at room temperature on a microfabricated 3D platform. The two-terminal resistance of the assembled SWNTs at 10 Vpp assembly(More)
This paper demonstrates a new paradigm for realization of functional devices on CMOS die/wafer based on nanomaterials such as carbon nanotubes and graphene, for chemical and biological sensing. This is made possible through a post-CMOS directed assembly approach based on dielectrophoresis (DEP); a low-cost, maskless approach electric-field based technique(More)
The biocompatibility, integrity, positional stability, and potential use of hermetically sealed injectable wireless micromachined microstimulators were investigated for reanimation of the paralyzed larynx. The device, consisting of silicon and glass, has been tested and proven to be biocompatible with no evidence of pathological tissue reaction or rejection(More)
