7© 2015 Elsevier Inc.The breakthrough of induced pluripotent stem cell technology has raised the possibility that patient-specific iPSCs may become a renewable source of autologous cells for cell therapy without the concern of immune rejection. However, the immunogenicity of autologous human iPSC -derived cells is not well understood. Using a humanized mouse model reconstituted with a functional human immune system, we demonstrate that most teratomas formed by autologous integration-free hiPSCs e…Read more

12© 2016 American Chemical Society.High quality WSe2 films have been grown on bilayer graphene with layer-by-layer control of thickness using molecular beam epitaxy. The combination of angle-resolved photoemission, scanning tunneling microscopy/spectroscopy, and optical absorption measurements reveal the atomic and electronic structures evolution and optical response of WSe2/BLG. We observe that a bilayer of WSe2 is a direct bandgap semiconductor, when integrated in a BLG-based heterostructure, th…Read more

5© 2015 Elsevier B.V.This article demonstrates an instrumented mouthguard capable of non-invasively monitoring salivary uric acid levels. The enzyme -modified screen printed electrode system has been integrated onto a mouthguard platform along with anatomically-miniaturized instrumentation electronics featuring a potentiostat, microcontroller, and a Bluetooth Low Energy transceiver. Unlike RFID-based biosensing systems, which require large proximal power sources, the developed platform enables re…Read more

2© 2015 American Chemical Society. We demonstrate straightforward fabrication of highly sensitive biosensor arrays based on field-effect transistors, using an efficient high-throughput, large-area patterning process. Chemical lift-off lithography is used to construct field-effect transistor arrays with high spatial precision suitable for the fabrication of both micrometer- and nanometer-scale devices. Sol-gel processing is used to deposit ultrathin In 2 O 3 films as semiconducting channel layers.…Read more
