Nanotechnology approaches to solve major problems on global scale: Report

Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some unique physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this area of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe drinking water for a growing population, as well as addressing issues in medicine, energy, and agriculture.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

Scientists develop novel chemotherapeutic method for anticancer drug delivery

Combining nature and Greek mythology, researchers at the Technion-Israel Institute of Technology have developed a tiny "Trojan Horse" system for delivering cancer-fighting drugs. With this system, the drugs are delivered only once they are inside the cancerous cells, so there is no damage to the healthy cells in the surrounding area.

Attaching transferrin to nanoparticle surface can kill cancer cells

A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.The finding could lead to a new strategy for targeted cancer therapies, according to the University of North Carolina at Chapel Hill scientists who made the discovery.

New York Times article highlights potential value of early cancer detection technology

Manhattan Scientifics, Inc. said today that a July 20th New York Times article titled "Prone to Error: Earliest Steps to Find Cancer" highlights the potential value of the early cancer detection technology developed by Senior Scientific, LLC and licensed by Manhattan Scientifics. The story focused on widespread problems associated with incorrect diagnosis of breast cancer, and cited one study in which 90,000 women either did not have the disease or their pathologist made an error that resulted in incorrect treatment.

Scientists develop carbon based nanoscale to detect single DNA molecules

Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.The pores, burned into graphene membranes using electron beam technology, provide Penn physicists with electronic measurements of the translocation of DNA.

Scientists develop nanoprobe to detect blood vessel growth in tumors

Formation of new blood vessels, also known as angiogenesis, is crucial for sustained tumor growth and cancer metastasis. Recently, clinically available therapies to suppress the growth of these vessels have been available to improve patient survival in some cancer types. Accurate detection and quantification of blood vessel growth using nonsurgical methods would greatly complement current therapies and allow physicians to quickly assess treatment regimens and adjust them as necessary. In the work published in the August issue of Experimental Biology and Medicine, Kessinger and coworkers have incorporated nanotechnology, material science, and the clinical imaging modality MRI, to create a nanosized probe capable of noninvasively visualizing and quantifying the blood vessel growth in tumors in a preclinical model.
