Prof. Rybtchinski’s self-assembling membrane for water purification
Separation technology is at the heart of water purification, sewage treatment, and materials reclamation, as well as numerous basic industrial processes. Membranes are used to separate out the smallest nanoscale particles, and even molecules and metal ions. Prof. Boris Rybtchinski and his group of the Weizmann Institute of Science’s Department of Organic Chemistry have developed a new type of membrane that could extend the life of a separation system, lower its cost and, in some cases, increase its efficiency as well.

Researchers working with tiny components in nanoelectronics face a challenge similar to that of parents of small children: teaching them to manage on their own. The nano-components are so small that arranging them with external tools is impossible. The only solution is to create conditions in which they can be “trusted” to assemble themselves.

Scientists from Israel and abroad have designed microscopic silk capsules that can serve as a protective environment for the transport of fragile protein “cargo” for cosmetic, food and pharmaceutical applications — particularly the delivery of drugs within the body.
The collaborative research, performed by an international team of academics from the Weizmann Institute of Science in Israel; the Universities of Cambridge, Oxford and Sheffield in the UK; and the ETH in Switzerland, was reported in Nature Communications on July 19.

In medicine's DNA age, doctors will make pre-emptive, targeted strikes on disease.
In one way, medicine hasn't changed much over the millennia: Doctors still wait for patients to feel sick before beginning treatment of an illness. Genomics promises to change that. By analyzing an individual's genetic makeup, physicians will be able to intervene early − and more precisely. "Generic treatments for certain diseases will be a thing of the past," says Elias Zerhouni, director of the National Institutes of Health. A malady can look the same in two patients, but be caused by a different series of physiological missteps, he explains. "Treatments will be tailored to your particular genomic background."

Breast cancer cells in culture form tubelike interconnections. In this image, payloads of molecules (inside blue circles) can be seen moving along these membranous nanotubes and microtubes, illustrating how they might be transmitted to a cell in need of them. Such connections may help cancer cells share their resistance to therapeutic drugs. Ian Smith
When the physician and scientist Emil Lou was an oncology fellow at Memorial Sloan Kettering Cancer Center about a decade ago, he was regularly troubled by the sight of something small but unidentifiable in his cancer-cell cultures. Looking through the microscope, he said, he “kept finding these long, thin translucent lines,” about 50 nanometers wide and 150 to 200 microns long, extending between cells in the culture. He called on the world-class cell biologists in his building to explain these observations, but nobody was sure what they were looking at. Finally, after delving into the literature, Lou realized that the lines matched what Hans-Hermann Gerdes’ group at the University of Heidelberg had described as “nanotubular highways” or “tunneling nanotubes” (TNTs) in a 2004 paper in Science.

A bowtie-shaped nanoparticle made of silver with a trapped semiconductor quantum dot (indicated by the red arrow)
Bowtie-shaped nanoparticles made of silver may help bring the dream of quantum computing and quantum information processing closer to reality. These nanostructures, created at the Weizmann Institute of Science and described recently in Nature Communications, greatly simplify the experimental conditions for studying quantum phenomena and may one day be developed into crucial components of quantum devices.

The Weizmann Institute of Science lies in the heart of green vegetation.
The Institute was chosen several times by The Scientist magazine as one of “the best places to work in academia.”
Here you can find all kinds of researchers at work - some are trying to defeat cancer while others are creating materials never seen before.
In this lab, Professor Reshef Tenne and his team are creating tiny crystals called nanoparticles. Nanoparticles can only be created under laboratory conditions.

Sep 21, 1997... A smooth, friction-free future may be in the offing—for machinery, that is. Prof. Reshef Tenne and his team in the Materials and Interfaces Department have created a new kind of lubricant that promises to cut friction in half. The synthetic material is made of inert, round molecules of tungsten disulfide. Says Prof. Tenne: "They just roll against each other and against the machinery parts, and don't stick to anything, like Teflon."

A cluster of gold nanoparticles under a transmission electron microscope. Empty spaces between the nanoparticles can serve as nanoflasks, as suggested by the drawing.
Miniature self-assembling “flasks” created at the Weizmann Institute of Science may prove to be a useful tool in research and industry. The nanoflasks, which have a span of several nanometers, or millionths of a millimeter, can accelerate chemical reactions for research. In the future, they might facilitate the manufacture of various industrial materials and perhaps even serve as vehicles for drug delivery.

Capturing a single photon from a pulse of light: Devices based on the Weizmann Institute model may be the backbone of future quantum communications systems
At the Weizmann Institute of Science, researchers have managed to “pluck” a single photon – one particle of light – out of a pulse of light. The findings of this research, which appeared November 24 in Nature Photonics, bear both fundamental and practical significance: Light is the workhorse of today’s communication systems, and single photons are likely to be the backbone of future quantum communication systems. In addition, say the scientists, the apparatus they have devised will spur further research into the fundamental particle nature of light.
