Journal ArticleDOI
Mesoporous silicon particles as a multistage delivery system for imaging and therapeutic applications
Ennio Tasciotti,Xuewu Liu,Rohan Bhavane,Kevin D. Plant,Ashley D. Leonard,B. Katherine Price,Mark Ming-Cheng Cheng,Paolo Decuzzi,James M. Tour,Fredika M. Robertson,Mauro Ferrari,Mauro Ferrari,Mauro Ferrari +12 more
TL;DR: A multistage delivery system that can carry, release over time and deliver two types of nanoparticles into primary endothelial cells is shown, based on biodegradable and biocompatible mesoporous silicon particles that have well-controlled shapes, sizes and pores.
Journal ArticleDOI
Antioxidant single-walled carbon nanotubes.
Rebecca M. Lucente-Schultz,Valerie C. Moore,Ashley D. Leonard,B. Katherine Price,Dmitry V. Kosynkin,Meng Lu,Ranga Partha,Jodie L. Conyers,James M. Tour +8 more
TL;DR: Cytotoxicity assays showed that both nonfunctionalized and BHT-derivatized SWCNTs have little or no deleterious effect on cell viability, suggesting that SWC NTs may be attractive agents for antioxidant materials and medical therapeutics research.
Journal ArticleDOI
Effective Drug Delivery, In Vitro and In Vivo, by Carbon-Based Nanovectors Noncovalently Loaded with Unmodified Paclitaxel
Jacob M. Berlin,Ashley D. Leonard,Tam T. Pham,Daisuke Sano,Daniela C. Marcano,Shayou Yan,Stefania Fiorentino,Zvonimir L. Milas,Dmitry V. Kosynkin,B. Katherine Price,Rebecca M. Lucente-Schultz,Xiaoxia Wen,M. Gabriela Raso,Suzanne L. Craig,Hai T. Tran,Jeffrey N. Myers,James M. Tour +16 more
TL;DR: Preliminary toxicity and biodistribution studies suggest that the PEG-HCCs are not acutely toxic and, like many other nanomaterials, are primarily accumulated in the liver and spleen.
Journal ArticleDOI
Diameter-Dependent Solubility of Single-Walled Carbon Nanotubes
Juan G. Duque,A. Nicholas G. Parra-Vasquez,Natnael Behabtu,Micah J. Green,Amanda L. Higginbotham,B. Katherine Price,Ashley D. Leonard,Howard K. Schmidt,Brahim Lounis,James M. Tour,Stephen K. Doorn,Laurent Cognet,Matteo Pasquali +12 more
TL;DR: The results highlight the importance of controlling SWNT synthesis methods in order to optimize processes dependent on solubility, including macroscopic processing such as fiber spinning, material reinforcement, and films production, as well as for fundamental research in type selective chemistry, optoelectronics, and nanophotonics.
Journal ArticleDOI
Nanoengineered carbon scaffolds for hydrogen storage.
Ashley D. Leonard,Jared L. Hudson,Hua Fan,Richard Booker,Lin Simpson,Kevin O'Neill,Philip A. Parilla,Michael J. Heben,Matteo Pasquali,Carter Kittrell,James M. Tour +10 more
TL;DR: 3-D nanoengineered fibers physisorb twice as much hydrogen per unit surface area as do typical macroporous carbon materials and points a way toward solving the volumetric and heat-transfer constraints that limit some other hydrogen-storage supports.
