Dear all.
Hope you like it! Please make comments. Many tks.
“Let me share a concept of with you. Its focus lies on human enhancement through the exponential technology available, such as: nanotechnology, genetics, AI, in order to lessen people’s suffering, stop aging and ultimately achieve a longer lifespan.” ❤️.
Scientists at The University of Manchester have created the world’s first ‘molecular robot’ that is capable of performing basic tasks including building other molecules. The tiny robots, which are a millionth of a millimetre in size, can be programmed to move and build molecular cargo, using a tiny robotic arm.
Each individual robot is capable of manipulating a single molecule and is made up of just 150 carbon, hydrogen, oxygen and nitrogen atoms. To put that size into context, a billion billion of these robots piled on top of each other would still only be the same size as a single grain of salt. The robots operate by carrying out chemical reactions in special solutions which can then be controlled and programmed by scientists to perform the basic tasks.
In the future such robots could be used for medical purposes, advanced manufacturing processes and even building molecular factories and assembly lines. The research will be published in Nature on Thursday 21st September.
Summary: Nanodocs? #Swallow #the #doctor? The authors of a recent research study, says soon we will be able to “swallow the surgeon.” Using medical #nanobots to diagnose and treat disease from inside the body. Study authors documented recent advances in nanotechnology tools, such as nanodrillers, microgrippers, and microbullets – and show how #nanodocs have tremendous potential in the areas of precision surgery, detection, detoxification and targeted drug delivery.

Imagine that you need to repair a defective heart valve, a major surgery. Instead of ripping your chest cut open, a doctor merely injects you with a syringe full of medical nanorobots, called nanodocs for short. You emerge from the ‘surgery’ unscathed, and your only external wound is the puncture hole from the injection.
According to a recent study published by nanorobotic engineers at the University of California San Diego (UCSD), the concept of ‘swallow the doctor’ may be closer to reality than we think.
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.

Google’s Futurist Ray Kurzweil once said that within decades, we will have nanobots, swimming through our veins keeping us healthy. The tiny robots will keep us healthy by correcting DNA errors, removing toxins, extending our memories and zapping cancer. The Futurist said that back in 2007, and his prophecy is becoming a reality, at least in the treatment of cancer.
Years spent developing bacteria-based nanobots are finally bearing fruit, and thanks to progress made by a physician at the Jewish General Hospital (JGH) in Montreal, cancer patients may be the first to be treated with tumor-killing nanorobots. The JGH doctors are using a newly-developed self-propelled, cancer-seeking nanorobot built out of bacteria and referred to as a bacteriobot, an amalgam of the words bacteria and nanorobot.
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.
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.
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.
Why Nanobots?
Chip makers have a mantra: smaller, cheaper, and faster. They may now need a new adjective—taller.
