Improved molecular targeting via cellular automata

In simplest terms, cellular automata can be thought of as groups of ‘cells’ in which the state of an individual cell will flip depending on the states of its neighbors. A ‘cell’ can be a pixel, a molecule, etc. The mathematical rules associated with cellular automation are complex and have been applied to fields as… Continue reading Improved molecular targeting via cellular automata

Nanoscale box aids single-molecule optical detection

Good old fashioned boxes are here to stay, even in the context of nanoscale devices. Across a broad range of technologies and size regimes, boxes serve as containers for components, barriers against contaminants and/or radiation, and, as in the case of cell membranes, can be permeable to allow selected interactions between the interior and exterior.… Continue reading Nanoscale box aids single-molecule optical detection

DNA nanotechnology positions components to optimize single-molecule fluorescence

A pillar constructed and positioned using DNA nanotechnology holds two gold nanoparticles and a dye molecule to enhance fluorescence over a hundred fold.

Nanotechnology, optical lithography, and petabyte data storage media

Two current-day nanotechnologies using two-different optical techniques and two different media will soon make possible petabyte data storage media, in one case with 100,000 times the storage lifetime of current optical disks.

Quantum dot conduction impacted by stoichiometry, not dangling bonds

Quantum dots are semiconducting, nanoscale clusters that show electronic characteristics distinct from both bulk-scale materials and single molecules. Their special characteristics make quantum dots attractive for a broad range of potential applications, including photovoltaics and nanoscale transistors. The size and shape of quantum dots impact electrical properties and can therefore be used to tune the… Continue reading Quantum dot conduction impacted by stoichiometry, not dangling bonds

Germanane: germanium&#39s answer to graphane

Soon after graphene sheets were being produced on a laboratory scale routinely, researchers began producing the hydrogenated version graphane (with a hydrogen atom on each carbon). This step is one of many approaches aimed at harnessing graphene’s powerful conductivity and is also being explored for hydrogen storage and other potential applications (more info in this… Continue reading Germanane: germanium&#39s answer to graphane

Silicene: silicon&#39s answer to graphene

**Updates: July 2014 — Research out of Argonne National Lab suggested that silicene may have never actually been successfully synthesized, rather that spectra indicate a mixture of silicon and silicon-substrate alloy; see article on Phys.org. August 2014 — Research out of Italy suggests that their spectra establish the presence of silicene though not in a… Continue reading Silicene: silicon&#39s answer to graphene

Superparamagnetism-explicated-for us

Even though the sound of it is something quite atrocious, superparamagnetism may become a familiar term in the context of nanoscale electronics and devices. Loosely speaking, superparamagnetism is a size-based phenomenon in which materials that are ferromagnetic on the macroscale — meaning predisposed toward strong magnetization at room temperature, such as iron and nickel —… Continue reading Superparamagnetism-explicated-for us

New advancement in 3D imaging of nanoparticles at atomic resolution

Researchers from UCLA’s California NanoSystems Institute and Northwestern University have combined multiple imaging techniques to produce high quality 3D images of platinum nanoparticles, allowing advanced visualization of atomic-scale structural defects (an important advancement over X-ray crystallography). The original 2012 work, published in Nature and posted by Jim Lewis here, used electron tomography to study 10-nm… Continue reading New advancement in 3D imaging of nanoparticles at atomic resolution

Computationally designed peptide sneaks nanoparticles past immune system

Nanoparticles decorated to avoid immune system recognition were tested in mice and shown to survive longer and deliver more imaging dye and drug to tumor cells.
