Nanotube-Enabled Vesicle-Vesicle Communication: A Computational Model.

The journal of physical chemistry letters

Zhang L, Wang X.
PMID: 26266730
J Phys Chem Lett. 2015 Jul 02;6(13):2530-7. doi: 10.1021/acs.jpclett.5b00755. Epub 2015 Jun 17.

Cell-to-cell communications via the tunneling nanotubes or gap junction channels are vital for the development and maintenance of multicellular organisms. Instead of these intrinsic communication pathways, how to design artificial communication channels between cells remains a challenging but interesting...

Field gradients can control the alignment of nanorods.

Langmuir : the ACS journal of surfaces and colloids

Ooi C, Yellen BB.
PMID: 18630934
Langmuir. 2008 Aug 19;24(16):8514-21. doi: 10.1021/la801006g. Epub 2008 Jul 17.

This work is motivated by the unexpected experimental observation that field gradients can control the alignment of nonmagnetic nanorods immersed inside magnetic fluids. In the presence of local field gradients, nanorods were observed to align perpendicular to the external...

Seeding, Plating and Electrical Characterization of Gold Nanowires Formed on Self-Assembled DNA Nanotubes.

Molecules (Basel, Switzerland)

Ranasinghe DR, Aryal BR, Westover TR, Jia S, Davis RC, Harb JN, Schulman R, Woolley AT.
PMID: 33092123
Molecules. 2020 Oct 20;25(20). doi: 10.3390/molecules25204817.

Self-assembly nanofabrication is increasingly appealing in complex nanostructures, as it requires fewer materials and has potential to reduce feature sizes. The use of DNA to control nanoscale and microscale features is promising but not fully developed. In this work,...

Use of a near-field optical probe to locally launch surface plasmon polaritons on plasmonic waveguides: a study by the finite difference time domain method.

Microscopy research and technique

Hwang BS, Kwon MH, Kim J.
PMID: 15549697
Microsc Res Tech. 2004 Aug;64(5):453-8. doi: 10.1002/jemt.20103.

We used the finite difference time domain (FDTD) method to study the use of scanning near field optical microscopy (SNOM) to locally excite the nanometric plasmonic waveguides. In our calculation, the light is funneled through a SNOM probe with...

Bio-mimic multichannel microtubes by a facile method.

Journal of the American Chemical Society

Vapor-phase hydrothermal growth of novel segmentally configured nanotubular crystal structure.

Small (Weinheim an der Bergstrasse, Germany)

Liu P, Zhang H, Liu H, Wang Y, An T, Cai W, Yang H, Yao X, Zhu G, Webb R, Zhao H.
PMID: 23589320
Small. 2013 Sep 23;9(18):3043-50. doi: 10.1002/smll.201300058. Epub 2013 Apr 16.

A new form of nanotubular crystal structure is directly grown by a vapor-phase hydrothermal method via an epitaxial orientated crystal growth mechanism. The as-prepared nanotubes possess a unique multi-tunnel core-shell layered nanotubular structure with droplet shaped polygonal periphery and...

Stabilization of DNA liquid crystals on doping with gold nanorods.

Physical chemistry chemical physics : PCCP

Brach K, Matczyszyn K, Olesiak-Banska J, Gordel M, Samoc M.
PMID: 26895042
Phys Chem Chem Phys. 2016 Mar 14;18(10):7278-83. doi: 10.1039/c5cp07026k.

We report on the impact of doping with gold nanorods (NRs) on the formation and stability of DNA liquid crystals (LCs). Cetyl trimethylammonium (CTAB)-stabilized gold NRs were synthesized using the wet chemistry method. Different textures of cholesteric and columnar...

Phase diagrams and morphological evolution in wrapping of rod-shaped elastic nanoparticles by cell membrane: a two-dimensional study.

Physical review. E, Statistical, nonlinear, and soft matter physics

Yi X, Gao H.
PMID: 25019819
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Jun;89(6):062712. doi: 10.1103/PhysRevE.89.062712. Epub 2014 Jun 24.

A fundamental understanding of cell-nanomaterial interaction is essential for biomedical diagnostics, therapeutics, and nanotoxicity. Here, we perform a theoretical analysis to investigate the phase diagram and morphological evolution of an elastic rod-shaped nanoparticle wrapped by a lipid membrane in...

Coherent stokes scattering from gold nanorods: critical dimensions and multicolor near-resonant plasmon excitation.

Nanoscale

Kim H, Herzing A, Michaels CA, Bryant GW, Stranick SJ.

Nanoscale. 2011 Oct 05;3(10):4290-5. doi: 10.1039/c1nr10825e. Epub 2011 Sep 13.

In this study, we detail the coherent Stokes scattering from gold nanorods in ensemble and single particle measurements. An increase of more than an order of magnitude was observed in the surface plasmon resonance enhancement of coherent Stokes scattering...
