#Plasmons Influence Carbon-Based Nanoparticles for Sensitizing Cancerous Tumors In a study published in EPJ D,
physicists have shown now that the production of low energy electrons by radio-sensitizers made of carbon nanostructures hinges on a key physical mechanism referred to as plasmons-collective excitations of so-called valence electrons;
Nanoparticle radio-sensitizers are nanoscale compounds, typically composed of rare metals such as coated gold, platinum, or gadolinium.
Alternatives sensitizers could be made of carbon-based nanostructures, such as fullerenes or nanotubes, provided they are biocompatible and nontoxic.
Previous studies have revealed that gold and platinum nanoparticles produce a large number of electrons via the plasmon excitation mechanism.
In the case of a carbon nanoparticle this phenomenon yields electrons with higher energy than pure metals,
thus inducing greater biological damage. In this study, the authors analysed the spectra of secondary electrons emitted from a carbon nanoparticle composed of fullerite,
a crystalline form of C60 fullerene, irradiated by an ion beam consisting of fast protons. They quantified the electron yield in a broad kinetic energy range,
using several different theoretical and numerical approaches. They found that a medium with an embedded carbon nanoparticle results in a number of low energy electrons several times higher than that emitted by pure water.
This may lead to the development of novel types of sensitizers composed of metallic and carbon-based parts.

#Researchers Use Synthetic Strands of DNA to Create Nanoparticle Clusters and Arrays The study has been described in the journal Nature Nanotechnology.
This is a new breakthrough on the use of DNA in nanoscale construction. The method resulted in arrays and clusters of nanoparticles,
which represent a major milestone for designing materials with customized functions and structures for applications in medicine, optics, and energy.
These arrays of nanoparticles with predictable geometric configurations are somewhat analogous to molecules made of atoms.
While atoms form molecules based on the nature of their chemical bonds, there has been no easy way to impose such a specific spatial binding scheme on nanoparticles.
This is exactly the problem that our method addresses said Brookhaven physicist Oleg Gang, who headed the project at the Lab's Center for Functional Nanomaterials (CFN), a DOE Office of Science User Facility.
According to the researchers, the novel technique would allow them to organize the arrangements of a variety of nanoparticles
and help them manipulate the synergistic or collective effects. Some of the examples comprise materials that deliver biomolecules,
The researchers designed the nanoparticle architectures by means of an octahedral scaffold, with particles placed in accurate locations on the scaffold as per the specificity of DNA coding.
which multiple nanoparticles of different structures and functions can be integrated,""stated Ye Tian, CFN scientist and one of the lead authors of the paper.
This method of nanoscale construction leverages two major properties of the DNA molecule, such as the natural tendency of strands having complementary bases,
In order to attach the nanoparticles to the 3d frames, the researchers designed each of the six-helix bundles in such a way that a single helix had an additional piece of single stranded-dna DNA sticking out from either ends.
When nanoparticles coated with single strand tethers are mixed with the DNA origami octahedrons the'free'pieces of DNA find one another so the bases can pair up according to the rules of the DNA complementarity code.
and the strands were fixed with a complementary sequence to gold nanoparticles. This resulted is a single gold nanoparticle fixed to individual octahedron's six vertices.
In further experiments the sequence of certain vertices was altered and complementary strands were utilized on a range of particles.
This is because the DNA molecules and nanoparticles, which constitute the frames, exhibit different densities. While some microscopy methods can show the particles alone
The images thus obtained showed that the new method used to direct the placement of nanoparticles on DNA-encoded vertices of molecular frames can prove to be effective for designing new nanomaterials.

#DNA NANOSTRUCTURES Assembled in Waterless Solvent Researchers at the Georgia Institute of technology have shown now that they can assemble DNA NANOSTRUCTURES in a solvent containing no water.
The research could open up new applications for DNA NANOTECHNOLOGY, and help apply DNA technology to the fabrication of nanoscale semiconductor and plasmonic structures.
Sponsored by the National Science Foundation and NASA the research will be published as the cover story in Volume 54, Issue 23 of the journal Angewandte Chemie International Edition.
NA nanotechnology structures are getting more and more complex, and this solvent could help researchers that are working in this growing field,
we have shown that DNA NANOSTRUCTURES can be assembled in a water-free solvent, and that we can mix water with the same solvent to speed up the assembly.
and have the DNA structures remain intact in the water-free solvent. he assembly rate of DNA NANOSTRUCTURES can be very slow,
This solvent also offers enhanced properties for nanotechnology and for the stability of these nanomaterials in solution. állego had worked in DNA NANOTECHNOLOGY before coming to Georgia Tech,
and was convinced that alternative solvents could advance this field. At Georgia Tech he evaluated new solvents for use with DNA NANOSTRUCTURES,
solvents that had been designed for other purposes. One solvent he tested, called glycholine that is a mixture of glycerol and choline chloride, allowed a two-dimensional DNA origami structure to assemble in six days at a temperature of 20 degrees Celsius.
Structures that fail to completely assemble are a major source of low yields in the DNA nanofabrication process. his solvent could provide a new tool to make more complicated designs with DNA
he added. inetic traps are among the bottlenecks for producing more complicated DNA NANOSTRUCTURES. lycholine is miscible in water,
A key feature of the new solvent system is that it does not require changes to existing DNA NANOTECHNOLOGY designs that were developed for water. ou can go back
said Gállego. his solvent system preserves the DNA structures that have been developed to work in water. he solvent system could improve the combined use of metallic nanoparticles and DNA based materials.
In the typical aqueous solvents where DNA NANOTECHNOLOGY is performed, nanoparticles are prone to aggregation. The solvent low volatility could also allow storage of assembled DNA structures without the concern that a water-based medium would dry out.
The research team which also included Martha Grover from Georgia Tech School of Chemical & Biomolecular engineering, has used so far the solvent to assemble three structures,
and investigate other solvents that may have additional properties attractive for nanotechnology applications. e were confident all along that we would find a solvent that would be compatible with existing DNA NANOTECHNOLOGY, added Hud,
because DNA NANOTECHNOLOGY was developed in water. he research on water-free solvents grew out of Georgia Tech research into the origins of life.
while also having applications in nanotechnology. his research was supported by the National Science Foundation (NSF) and the NASA Astrobiology Program under the NSF Center for Chemical Evolution (CHE-1004570).

A nanometer is one billionth of a meter, and some nanomaterials are only a few atoms in size.
The method described in the Scientific Reports article tructural color printing based on plasmonic metasurfaces of perfect light absorptioninvolves the use of thin sandwiches of nanometer scale metal-dielectric materials known as metamaterials that interact with light

#Scientists Demonstrate Intrinsic Chirality in Ordinary Nanocrystals By Stuart Milnethese findings have opened new possibilities in medicine,
biotechnology and nanobiotechnology for applications including targeted drug delivery. Chirality of an object is its property that allows it to be non-superimposable with its mirror image.
Ever since the development of artificial nanocrystals, scientists thought that chirality was either random or completely absent in nanocrystals.
Researchers from Trinity college Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN), partnered with collaborators from ITMO University Optics of Quantum Nanostructures laboratory in a joint experiment to show that standard nanocrystals were made up a 50:50
mixture of'left'and'right'chiral forms. Standard nanocrystals are composed of cadmium selenide quantum dots and quantum rods.
Artificial chiral nanocrystals can be produced by fastening special chiral ligand molecules to the nanocrystal surface.
In the natural world, chirality is an inherent property of many objects that range from spiral galaxies to elementary particles.
or right, depending upon the nanocrystal chiral form. Theoretically, optical activity is observed not in any normal nanocrystal solution.
The absence of chirality in nanocrystals has been considered to be the cause of optical activity. In this study, the researchers have proved the opposite,
by dividing the nanocrystal'left'and'right'forms. Yurii Gun'ko, professor at Trinity college and co-director of International Research and Education Centre for Physics of Nanostructures at ITMO University comments on potential applications of the method developed by the group:
The scientists developed a technique for separating various forms of nanocrystals and also capture their intrinsic chirality manifestation.
This technique could possibly be expanded and then used with various other inorganic nanomaterials. In an unmixable two-phase solution composed of an organic solvent (chloroform) and water,
nanocrystals were immersed. Nanocrystals do not dissolve in water; hence L-cysteine was added to transfer the nanocrystals in organic phase to water.
L-cysteine is a chiral molecule and it is used widely for phase transfers as a ligand.
Nanocrystals have hydrophobic ligands on their surface, and cysteine replaces these ligands and makes the material soluble in water.
Hence, all the nanocrystals will be in water, irrespective of the cysteine chiral form. When this solution was cooled
and the phase transfer was interrupted at a specific point, a particular situation where the nanocrystal ensemble was divided equally between the phases that had nanocrystals both'left'and'right'-in different phases.
Furthermore removal of cysteine does not affect the nanocrystal optical activity due to this separation. This provides more proof to the existence of intrinsic chirality in nanocrystals.
Vladimir G. Maslov, Anatoly V. Fedorov, Alexander V. Baranov, Finn Purcell-Milton, Anna O. Orlova,
and Joseph Govan were other researchers who took part in this study. The research team has published their study titled,'Intrinsic chirality of Cdse/Zns quantum dots and quantum rods,'in Nano Letters e
