Journal ArticleDOI
Rheology and Phase Behavior of Lyotropic Cellulose Nanocrystal Suspensions
TL;DR: The dispersion microstructure and rheological properties of aqueous sulfonated cellulose nanocrystal (CNC) suspensions have been investigated in this article, where the suspensions phase separated into liquid crystalline and isotropic domains.
Journal ArticleDOI
DNA-Controlled Partition of Carbon Nanotubes in Polymer Aqueous Two-Phase Systems
TL;DR: It is shown that partition of DNA-SWCNT hybrids in a given polymer two-phase system is strongly sequence-dependent and can be further modulated by salt and polymer additives, as well as the sensitive dependence of the hydration energy on the spatial distribution of hydrophilic functionalities.
Journal ArticleDOI
Differentiating Left- and Right-Handed Carbon Nanotubes by DNA.
TL;DR: This work applies polymer aqueous two-phase systems to select special DNA-wrapped carbon nanotubes that must have an ordered DNA structure that binds to a nanotube of defined handedness and helicity and resembles a well-folded biomacromolecule with innate stereoselectivity.
Journal ArticleDOI
Narrow-band single-photon emission through selective aryl functionalization of zigzag carbon nanotubes
Avishek Saha,Brendan J. Gifford,Brendan J. Gifford,Xiaowei He,Geyou Ao,Ming Zheng,Hiromichi Kataura,Han Htoon,Svetlana Kilina,Sergei Tretiak,Sergei Tretiak,Stephen K. Doorn +11 more
TL;DR: It is shown that the structural symmetry of zigzag nanotubes and a high chemical selectivity for ortho configurations results in defect-state emission from a single narrow band.
Journal ArticleDOI
An optical nanoreporter of endolysosomal lipid accumulation reveals enduring effects of diet on hepatic macrophages in vivo.

TL;DR: It is found that elevated lipid quantities in hepatic macrophages caused by a high-fat diet persist long after reverting to a normal diet, hindering preclinical drug development and research into the mechanisms linking endolysosomal lipid accumulation to disease progression.
