VTT Finland develops 3D printed device for advanced wound care
Posted by Klaus Baldauf in categories: 3D printing, biotech/medical, nanotechnology
Cellulose is the most abundant organic polymer in the world. It is the primary compound in the cell walls of green plants, and is typically used to make paper and cardboard.
At the VTT Technical Centre of Finland, a state owned research and development non-profit, scientists have used nano-structured cellulose to make a 3D printable material.
The nanocellulose paste is now in development to make smart-dressings that heal and monitor skin wounds.

The new self-propelled, cancer-seeking bacteriobot swims right into the tumor and zaps it with a deadly payload of cancer drugs.
The recently perfected #bacteriobot holds ‘a lot of promise’ in treating #cancer says a physician. Cancer patients at a hospital in Montreal may be the first to be treated with these #nanorobots built out of bacteria.

The application of nanotechnology to cardiovascular nanomedicine
Posted by Dan Kummer in categories: biotech/medical, nanotechnology
Nanostructured systems have the potential to revolutionize both preventive and therapeutic approaches for treating cardiovascular disease. Given the unique physical and chemical properties of nanostructured systems, nanoscience and nanotechnology have recently demonstrated the potential to overcome many of the limitations of cardiovascular medicine through the development of new pharmaceuticals, imaging reagents and modalities, and biomedical devices. A recent review offers an outline of critical issues and emerging developments in cardiac nanotechnology.

Nanotechnology experts create first terahertz-speed polarization optical switch
Posted by Saúl Morales Rodriguéz in categories: electronics, nanotechnology
A Sandia National Laboratories-led team has for the first time used optics rather than electronics to switch a nanometer-thick thin film device from completely dark to completely transparent, or light, at a speed of trillionths of a second.
The team led by principal investigator Igal Brener published a Nature Photonics paper this spring with collaborators at North Carolina State University. The paper describes work on optical information processing, such as switching or light polarization control using light as the control beam, at terahertz speeds, a rate much faster than what is achievable today by electronic means, and a smaller overall device size than other all-optical switching technologies.
Electrons spinning around inside devices like those used in telecommunications equipment have a speed limit due to a slow charging rate and poor heat dissipation, so if significantly faster operation is the goal, electrons might have to give way to photons.

A DNA nanorobot is programmed to pick up and sort molecules into predefined regions
Posted by Klaus Baldauf in categories: bioengineering, biotech/medical, nanotechnology, robotics/AI
Imagine a robot that could help you tidy your home: roving about, sorting stray socks into the laundry and dirty dishes into the dishwasher. While such a practical helper may still be the stuff of science fiction, Caltech scientists have developed an autonomous molecular machine that can perform similar tasks—at the nanoscale. This “robot,” made of a single strand of DNA, can autonomously “walk” around a surface, pick up certain molecules and drop them off in designated locations.
The work was done in the laboratory of Lulu Qian, assistant professor of bioengineering. It appears in a paper in the September 15 issue of Science.

Kurzweil is one of the world’s leading minds on artificial intelligence, technology and futurism. He is the author of five national best-selling books, including “The Singularity is Near” and “How to Create a Mind.”
Raymond “Ray” Kurzweil is an American author, computer scientist, inventor and futurist. Aside from futurology, he is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, and gives public talks to share his optimistic outlook on life extension technologies and the future of nanotechnology, robotics, and biotechnology.

Nanomachines that drill into cancer cells killing them in just 60 seconds developed by scientists
Posted by Klaus Baldauf in categories: biotech/medical, nanotechnology
Nanomachines which can drill into cancer cells, killing them in just 60 seconds, have been developed by scientists.
The tiny spinning molecules are driven by light, and spin so quickly that they can burrow their way through cell linings when activated.
In one test conducted at Durham University the nanomachines took between one and three minutes to break through the outer membrane of prostate cancer cell, killing it instantly.
