Rebranding the same old science!

Old Wine in a New Bottle?

What is nanoscience? Is it different from nanotechnology? Is it chemistry? Many chemists do think that nanoscience is another word for molecular chemistry. However, there are many who would argue with that definition (including the physicists, mechanical engineers, chemical engineers, bioengineers working in nanotechnology). Is molecular physics also nanoscience?

Though my own effort to understand nano science and technology over the last couple of years (as a journalist) and more so, after deciding to start the magazine, from last six months, has been that it is the same old science that Democritus, Rutherford, Rustom Roy, Milburn, etc have been talking about.

Hence I have been toying on the idea whether to ask this question or not… but after seeing the response that people have showered upon us for the blog, I assume I will get the answer!!!!

Best part that nano has brought in is that the youngsters think it is the most happening science and they are ready to show keen interest in this rather than “boring” chemistry and physics. By facing this happening tag to our good old science we are able to attract more kids to seriously take up nanotechnology!

What difference does the name make? Do kids seek out nano-related activities over more traditionally named activities? Or is this just rebranding of the same old science or is it something new? Can we make nanoscience something different?

If anyone has better way to explain nanotechnology please let me know. It would be of great help to understand….

Stanford writes in world’s smallest letters

Storing information in electron waves

The researchers encoded the letters “S” and “U” (as in Stanford University) within the interference patterns formed by quantum electron waves on the surface of a sliver of copper. The wave patterns even project a tiny hologram of the data, which can be viewed with a powerful microscope.

“We miniaturized their size so drastically that we ended up with the smallest writing in history,” said Hari Manoharan, the assistant professor of physics who directed the work of physics graduate student Chris Moon and other researchers.

The quest for small writing has played a role in the development of nanotechnology for 50 years, beginning decades before “nano” became a household word. During a now-legendary talk in 1959, the remarkable physicist Richard Feynman argued that there were no physical barriers preventing machines and circuitry from being shrunk drastically. He called his talk “There’s Plenty of Room at the Bottom.”

Feynman offered a $1,000 prize for anyone who could find a way to rewrite a page from an ordinary book in text 25,000 times smaller than the usual size (a scale at which the entire contents of the Encyclopedia Britannica would fit on the head of a pin). He held onto his money until 1985, when he mailed a check to Stanford grad student Tom Newman, who, working with electrical engineering Professor Fabian Pease, used electron beam lithography to engrave the opening page of Dickens’ A Tale of Two Cities in such small print that it could be read only with an electron microscope.

That record held until 1990, when researchers at a certain computer company famously spelled out the letters IBM by arranging 35 individual xenon atoms.

Now, in a paper published online in the journal Nature Nanotechnology, the Stanford researchers describe how they have created letters 40 times smaller than the original prize-winning effort and more than four times smaller than the IBM initials. (

Working in a vibration-proof basement lab in the Varian Physics Building, Manoharan and Moon began their writing project with a scanning tunneling microscope, a device that not only sees objects at a very small scale but also can be used to move around individual atoms. The Stanford team used it to drag single carbon monoxide molecules into a desired pattern on a copper chip the size of a fingernail.

On the two-dimensional surface of the copper, electrons zip around, behaving as both particles and waves, bouncing off the carbon monoxide molecules the way ripples in a shallow pond might interact with stones placed in the water.

The ever-moving waves interact with the molecules and with each other to form standing “interference patterns” that vary with the placement of the molecules.

By altering the arrangement of the molecules, the researchers can create different waveforms, effectively encoding information for later retrieval. To encode and read out the data at unprecedented density, the scientists have devised a new technology, Electronic Quantum Holography.

In a traditional hologram, laser light is shined on a two-dimensional image and a ghostly 3-D object appears. In the new holography, the two-dimensional “molecular holograms” are illuminated not by laser light but by the electrons that are already in the copper in great abundance. The resulting “electronic object” can be read with the scanning tunneling microscope.

Several images can be stored in the same hologram, each created at a different electron wavelength. The researchers read them separately, like stacked pages of a book. The experience, Moon said, is roughly analogous to an optical hologram that shows one object when illuminated with red light and a different object in green light.

For Manoharan, the true significance of the work lies in storing more information in less space. “How densely can you encode information on a computer chip? The assumption has been that basically the ultimate limit is when one atom represents one bit, and then there’s no more room—in other words, that it’s impossible to scale down below the level of atoms.

“But in this experiment we’ve stored some 35 bits per electron to encode each letter. And we write the letters so small that the bits that comprise them are subatomic in size. So one bit per atom is no longer the limit for information density. There’s a grand new horizon below that, in the subatomic regime. Indeed, there’s even more room at the bottom than we ever imagined.”

In addition to Moon and Manoharan, authors of the Nature Nanotechnology paper, “Quantum Holographic Encoding in a Two-Dimensional Electron Gas,” are graduate students Laila Mattos, physics; Brian Foster, electrical engineering; and Gabriel Zeltzer, applied physics.

The research was supported by the Department of Energy through SLAC National Accelerator Laboratory and the Stanford Institute for Materials and Energy Science (SIMES), the Office of Naval Research, the National Science Foundation and the Stanford-IBM Center for Probing the Nanoscale.

‘Nanotechnology can cure cancer’

HYDERABAD: A genetic research specialist from the twin cities Rao Papineni, working with Carestream Health Inc, USA, along with other top researchers has devised a method to treat cancer cells by using nanotechnology.

The researcher who is here to take part in the upcoming BioAsia-09 said that the ‘invention’ is in U.S. patent process. It’s a known fact that nanotechnology can be used to develop ways to kill cancer cells in the body without damaging the healthy cells. “We have developed image-guided targeted cancer-cell killers. The unique aspect is that we can deliver large loads of drugs to the cancerous region without actually affecting the healthy cells,” Dr. Papineni said.

The researcher is in the process of meeting local scientific and research community in India and discuss about the invention. “We are hoping that people back home here will notice such developments during the BioAsia 2009. I have already presented a paper on the same subject in Nanobio-2009 held recently in Kochi,” he said.

Along with a research team consisting of Dr. Alan Pollock and Dr. Mansoor Ahmed at University of Miami, Florida, plans are afoot to use the cancer killer nanoparticles in curing prostrate cancer. “It’s not just prostrate cancer; other cancers can also be cured.” Dr. Rao is also working on a process to make nanoparticles carry large doses of Curcumin (Haldi), which has anti-cancer properties, with another Indian researcher Bharat Agarwal. “Apart from its known use in plastics, energy, and aerospace industry, nanotechnology is beginning to grow rapidly in medical imaging and therapeutics,” he said.

Multitasking Nanotechnology

Confocal microscope image of a self-assembled monolayer of a polychlorotriphenyl methyl radical patterned on a quartz surface. This multifunctional molecule behaves as an electroactive switch with optical and magnetic response.

Tiny electronically active chemicals can be made to form ordered layers on a surface, thanks to research supported by the European Science Foundation (ESF) through the EUROCORES programme SONS 2 (Self-Organised NanoStructures).

These nanostructured layers may one day be used to build the components of electronics devices, such as transistors and switches, for a future generation of powerful computers based on molecules rather than silicon chips.

Speaking at the European Materials Research Society (EMRS) meeting in Strasbourg, SONS II scientist Marta Mas-Torrent explained the potential of nanotechnology: “Currently, there is a great interest in employing functional molecules as building blocks for preparing devices since this will facilitate the move towards device miniaturization.”

On this scale, manipulating nanoscopic components requires skill and determination but by exploiting molecular self assembly, the researchers hope to build ordered layers just a single molecule thick using microcontact printing techniques borrowed from the electronics industry.

They are now creating different arrangements of monolayers on gold, silica, and other materials.

EMSI Conference brings forth the new trends

EMSI Conference brings forth the new trends
Paves way for greater research in Nano science

Inauguration of National Conference on Electron Microscopy and Allied Fields at Bundelkhan University, Jhansi

Scientific Exhibition at the Conference

The National Conference of Electron Microscope Society of India (EMSI – 2009) was held at Bundelkhand University in Jhansi from January 17-19, 2009. This annual conference promoted interdisciplinary research, bridging various scientific and technical disciplines. The conference brought various scientists from across the country to work in different disciplines to discuss the various aspects of microscopy.

Dr Peter Koshy, outgoing president of EMSI, mentioned that, “Electron Miscroscopy has paved way to the birth nanotechnology, but this has not really got its due importance in the country for various reasons. Thanks to major push in nanotechnology by the government and private organizations, this field is now looked forward.”

The electron microscope needs no introduction. It has been hailed as one of the most important inventions of the 20th century. Since it was first unveiled, the electron microscope has undergone many technical improvements and seen the incorporation of new designs, among them the scanning tunneling electron microscope. But nonetheless, the pioneering attempt of Ernst Ruska was rewarded with one half of the 1986 Nobel Prize in Physics for his fundamental work in electron optics and for the design of the first electron microscope. The other half went jointly to Dr Gerd Binnig and Dr Heinrich Rohrer for their design of the scanning tunneling microscope. Today almost no branch of science can do without electron microscope, which has been the tool to reveal many of nature’s mysteries.

The conference discussed advances in the electron microscopy techniques as also the understanding of new and exotic materials and their consequent applications of relevance to the society. More importantly, the new nanoscale analytical techniques have made it possible to understand and also help create matter on a nanoscale and thus have ushered in an era of what is now popularly called nano science and nanotechnology.

Explaining about the importance newly appointed president of EMSI R P Tandon says, “Today our country is being recognized for its large pool of excellent human resources in science and technology and it is high time they are brought to the lime light. In view of encouraging our scientists, academicians, and young researchers for the future, this is the purpose of the conference.”

EMSI found one of its missions to identify the scientific brilliance in the country, recognize their scientific contributions and honour them with different prestigious awards during the annual meeting. Dr Srikumar Banerjee, director of Baba Atomic Research Centre, Mumbai was presented with Lifetime Achievement Award for 2008-09 while Dr PD Gupta of CCMB was given the same award in Biological Sciences category. For the first time the Society has instituted Fellow of EMSI and has given this honour to 10 prominent people: Prof K Chattopadhyay, Dr MS Rao, Dr Fazil Marickar, Prof RP Tandon, Dr G K Dey, Dr Sudip Dey, Dr Sabu Thomas, Dr Indradev Samajdar, Dr P Prabhakar Rao and Dr Prakash Kumar.

Apart from the conference, there was a scientific exhibition with various corporate players displaying their newest products and technologies. Major players participated in this much awaited exhibition: Icon Analytical, Gatan, Jeol, Blue Star, Carl Zeiss, Forevision Instruments, Oxford Instruments, Camscan, Mars Scientific & Bruker Miscroanalysis, Tinsley-Wayne Kerr, Sree Analytical, Labindia Instruments, Ants Ceramics, Metrex and Advance Scientific & Tescan.

Nano India magazine took this opportunity to meet and inform about the impending launch of the magazine. Flyers were distributed to all the participants of the conference generating curiosity to know about the magazine.
