In a study with breast cancer in mice,Investment Banks a nanotech cancer therapy suppresses tumor growth with minimal side effects. Taking advantage of the fact that the blood vessels in tumor tissue are leakier than in normal tissue, carbon nanotubes of the right size and with the proper chemical coating deliver more tumor-killing drug to [...]
Advanced nanotech would benefit from the ability to engineer atomically precise structures on nanoparticles. In a step in that direction, UK scientists have developed a combined computational and experimental method to determine how specific peptides self-assemble on the surface of a gold nanoparticle—in particular how closely spaced on the surface of the nanoparticle the peptides [...]
Two stories today in ScienceDaily point to different nanotech applications that could enable a solar solution to our energy problems—one including the use of self-repairing nanosystems. “” describes the use of photoactive nanoscale systems to develop molecular electronics. Organic molecules and fullerenes will be used to make inexpensive photovoltaics and light emitting diodes:
Organic photovoltaics and [...]
The protein engineering pathway to advanced nanotech (see “Protein Bioengineering Overview”, paper 10 of the Productive Nanosystems Roadmap “:
Scientists at The University of Manchester have developed a new and fast method for making biological ‘chips’ — technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of [...]
Government-sponsored discussions of the implications for society of advanced nanotechnology and other emerging technologies have taken place and are ongoing in both the US and Europe. A recent Nanowerk Spotlight written by Michael Berger gives an update of deliberations in Europe and compares and contrasts the US and European approaches. From ““:
The two differing approaches [...]
To form practical nanotech circuits from arrays of nanowires, it is necessary to integrate different types of nanowires into multifunctional circuits. Two different types of nanowires (cadmium selenide for light sensors and germanium core/silicon shell for field-effect transistors) have been integrated on a chip to detect and amplify optical signals. From Lawrence Berkeley National [...]

In March 2008, eighty-six people across six nationwide panels participated in the National Citizens’ Technology Forum on “Human Enhancement Through Nanotechnology.” These citizens ranged from teens to seniors and had no previous expertise or experience in nanotechnology. They studied background material, met face-to-face, and participated in nine, two-hour Internet discussion forums with scientist experts. [...]
Silver nanoparticles continue to show promise for killing bacteria, “:
Chemical Engineers in Switzerland have created a plastic film that’s up to 1000 times more effective at killing E. coli bacteria cells than conventional methods.
The team from the Swiss Federal Institute of Technology, Zurich have discovered that coating the film with a mix of silver and [...]

The government is seizing the management of the “veteran” pension fund belonging to the National Workers Organization because of insider transactions carried out without the fund’s greater good in mind.
Yadin Antebi, the commissioner of capital markets, insurance and savings at the Finance Ministry, yesterday told the National Workers Organization (Histadrut Ovdim Leumit, which is not [...]
