Nanotechnology May Be Used to Regenerate Tissues, Organs
Research at Northwestern University has shown that a combination of nanotechnology and biology may enable damaged tissues and organs to heal themselves. In a presentation at the Woodrow Wilson International Center for Scholars in Washington DC last week, Samuel I. Stupp, board of trustees professor of materials science, chemistry, and medicine, and director of the Institute for BioNanotechnology in Medicine (IBNAM), reported on his work that suggests nanotechnology can be used to mobilize the body's own healing abilities to repair or regenerate tissues and organs. Stupp was the featured speaker at the launching of a new report NanoFrontiers: Visions for the Future of Nanotechnology from the Center's Project on Emerging Nanotechnologies. The project was co-sponsored by the Directors of the NIH and the NSF.

Evidence of Nanoparticles Found In Plaque-Filled Arteries
Scientific evidence increasingly links arterial calcification to the presence of nanosized particles so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.A new Mayo Clinic study cites evidence showing the presence of nanoparticles near plaque-filled arteries in animal models. The study suggests that nanoparticles potentially represent a previously unrecognized factor in the development of arteriosclerosis and calcific arterial disease. The study will be presented during the 2007 Experimental Biology meeting in Washington, D.C., on April 29.

Risks and Benefits of Nano-Silver
Nanosilver products can be found in an increasing number of consumer products such as food packagings, textiles, cosmetics and cleaning devices. Silver has been known for its antibacterial properties for centuries, and (nano-) silver is thought to be able to damage bacterial cells by destroying the enzymes that transport cell nutrients and by weakening the cell membrane or the cell wall.A more recent study by the University of Hong Kong has shown that nanosilver allows wounds to heal faster than using conventional antibiotics. In this study, the researchers treated wounds with conventional antibiotics, with nano-silver antibiotics and without any antibiotics. The silver nanoparticles led to complete healing within 25 days, while the conventionally treated wounds healed in 29 days and it took 35 days in the case the wounds were left untreated (2). Therefore, the application of nanosilver represents an opportunity to save costs in the medical care sector.
In the year 2005, a study by the University of Texas and the Mexican University reported that nanosilver was even able to inhibit viruses. The results suggested that silver nanoparticles interact with the HIV-1 virus via preferential binding to certain glycoprotein knobs. Due to this interaction, silver nanoparticles inhibit the virus from binding to host cells, as demonstrated in vitro (1). However, scientists and environmentalists worry that excessive use of silver might allow it to seep into the environment, where it could kill small organisms and disrupt the ecosystem by killing beneficial bacteria essential to soil, plant and animal health. Scientists also have the serious apprehension that the use of nanosilver will lead to the development of antibiotic resistance among bacteria, which already represents a major problem in infection treatment today (3). So far, the exact mechanisms of interaction and the impacts of nanosilver on the environment are largely unknown. Once more, the opportunities have to be carefully balanced against potential risks, and a lot of research is still necessary.

Nanotech Capsules May Aid TB Treatment
South Africa's Council for Scientific and Industrial Research (CSIR) is collaborating with Ayanda Biosystems, based at the Swiss Federal Institute of Technology in Lausanne, to develop a nanoparticle-encapsulated treatment for tuberculosis (TB). At the World Nano Economic Congress held last week in Pretoria, South Africa's Deputy Minister of Science and Technology Derek Hanekom said that existing treatments for TB can be problematic in terms of patient compliance because they require the patient to take four drugs over the course of several weeks or months. Owing to the slow degrading and the slow release mechanism of the carrier systems, drug release can be prolonged through nano-based drug delivery systems, allowing for the administration of drugs once in seven days, instead of the current daily dosage. The nanocapsules were being tested on animals.
Hanekom further explained that 250’000 new cases of TB are diagnosed each year in South Africa and that coinfection of HIV/AIDS has made TB one of the area's leading causes of death. Nano-based drug delivery systems are also being developed for malaria, HIV/AIDS, and other diseases with treatments that require patient compliance. According to Hanekom, the South African government has initiated a number of nanotechnology research and development programs and is setting up two nanotechnology research centres.

Bucky's brother: the boron buckyball makes its debut -Materials scientists find stable, spherical form for boron
A new study by Rice University scientists predicts the existence and stability of another "buckyball" consisting entirely of boron atoms. The research, which has been published online and is due to appear as an editor's selection in Physical Review Letters, was conducted bv Boris Yakobson, professor of mechanical engineering and materials science and of chemistry, and his associates Nevill Gonzalez Szwacki and Arta Sadrzadeh. The original buckyball, a cage-shaped molecule of 60 carbon atoms, was discovered at Rice by Robert Curl, Harold Kroto and Richard Smalley in 1985. The boron buckyball is structurally similar to the original C60 fullerene, but it has an additional atom in the center of each hexagon, which significantly increases stability.

3-D Nano Images- IBM researchers have developed a nuclear MRI technique that can see features as small as 90 nanometers.
Understanding the functions of proteins often requires knowing their 3-D structures. But deciphering a protein's structure is a time-consuming and difficult task, typically requiring crystallizing the proteins and bombarding them with x-rays. What's more, scientists have not been able to crystallize thousands of proteins, so their structures remain unknown. A far better option would be an analytic method that allowed biologists to directly determine protein structures. So Dan Rugar, manager of nanoscale studies at IBM's Almaden Research Center, in San Jose, CA, and his colleagues are developing an imaging technique, based on magnetic resonance imaging (MRI), that allows scientists to see a protein's structure in three dimensions, just as MRI scans show 3-D snapshots of the human body. Conventional MRI can make out features down to three micrometers.To image a protein or other biomolecule in three dimensions, the researchers hope to bring the resolution of the MRI method down to less than one nanometer so that they can pinpoint the location of individual atoms in a protein. Scientists could then reconstruct the protein's structure.

Nanotechnology pesticide filter debuts in India
A domestic water filter that uses metal nanoparticles to remove dissolved pesticide residues is about to enter the Indian market. Its developers at the Indian Institute of Technology (IIT) in Chennai (formerly Madras) believe it is the first product of its kind in the world to be commercialised. The mechanism of removal is 'adsorption followed by catalytic destruction', Pradeep explained. 'The chemistry occurs in a wide concentration range of environmental significance.' He added that tests proved silver particles from the filter are not released into the water. Eureka already markets a water purifier that combines a sedimentation chamber with activated carbon filters and UV irradiation, and costs around Rs8500 (approx. $200). Reddy estimated that adding the x-centimetre-long nanosilver cartridge (see image) to remove pesticides will increase the price by 15 per cent, but silver recycling (in an environmentally-friendly manner, stressed Pradeep) should help to reduce that cost.

Nanoparticles can damage DNA, increase cancer risk
Tissue studies indicate that nanoparticles could damage DNA and lead to cancer, according to research presented at the 2007 Annual Meeting of the American Association for Cancer Research. Nanoparticles are small enough to penetrate cell membranes and defenses, yet they are large enough to cause trouble by interfering with normal cell processes, researchers at the University of Massachusetts say. Such nanoparticles are currently in use in electronics, cosmetics, and chemical manufacturing, among others industries. Because of their extremely small size, they can be difficult to isolate from the larger environment, as they are much too small for removal by conventional filtering techniques. When nanoparticles find their way into cancer cells, they can wreak havoc, according to Sara Pacheco, an undergraduate researcher at the University of Massachusetts. Yet very little is known about how they behave in the environment or how they interact with and affect humans.

Improving Blood Stem Cell Transplants, Bioseparations Using Magnetic Nanoparticles
Whether the goal is to separate different types of cells or molecules, methods that rely on the age-old principle of magnetism are a staple among researchers. Now, two reports show that the use of magnetic nanoparticles in bioseparations could have a significant impact on both clinical oncology and basic cancer research.Reporting its work in the journal Biotechnology and Bioengineering, a research team headed by Maciej Zborowski, Ph.D., demonstrated that magnetic nanoparticles, combined with antibodies, successfully enriches peripheral blood progenitor cells (PBPCs) in samples of whole blood. Clinical trials have shown that PBPCs are more effective than bone marrow transplantation at restoring an individual’s blood cells population following high-dose chemotherapy or radiation therapy.

Self-Assembling Nanoparticle Releases Drug Into Cell Cytoplasm
A growing body of research leaves no doubt that nanoparticles can transport drugs into cancer cells, but what is less clear is that the drug payload can exit the tiny endosomes that pull nanoparticles into cells. As a result, there is still some concern that only a small portion of a nanoparticle’s drug payload will actually get into the cell’s cytoplasm and attack its intended intracellular molecular target.
