Banning carbon nanotubes would be scientifically unjustified and damaging to innovation

Ardemis Anoush Boghossian, Junichiro Kono

Nature Publishing Group2020

Analytical Approaches for Monitoring DNA–Protein Interactions

Ardemis Anoush Boghossian, Shang-Jung Wu

DNA–protein interactions play a critical role in cellular regulation. We herein review existing analytical methods for investigating these interactions, highlighting methods such as chromatin immunoprecipitation and yeast-one-hybrid that are used to identi ...

Non-covalent Methods of Engineering Optical Sensors Based on Single-Walled Carbon Nanotubes

Ardemis Anoush Boghossian, Alice Judith Gillen

Optical sensors based on single-walled carbon nanotubes (SWCNTs) demonstrate tradeoffs that limit their use in in vivo and in vitro environments. Sensor characteristics are primarily governed by the non-covalent wrapping used to suspend the hydrophobic SWC ...

Spinning-disc confocal microscopy in the second near-infrared window (NIR-II)

Vitalijs Zubkovs, Ardemis Anoush Boghossian, Alessandra Antonucci, Benjamin Paul Johanès Gabriel Lambert

Fluorescence microscopy in the second near-infrared optical window (NIR-II, 1000–1350 nm) has become a technique of choice for non-invasive in vivo imaging. The deep penetration of NIR light in living tissue, as well as negligible tissue autofluorescence w ...
