University of Toronto Engineering researchers have built a set of magnetic 'tweezers' that can position a nano-scale bead inside a human cell in three dimensions with unprecedented precision. The nano-bot has already been used to study the properties of cancer cells, and could point the way toward enhanced diagnosis and treatment. Professor Yu Sun [...]
When you were a kid, did you ever sign a classmate’s cast after they broke an arm or a leg? Your name would be on display there for the rest of the semester. Broken bones are one of the worst trade-offs in childhood—a few seconds of calamity followed by months of boring rest and [...]
Inventors and scientists have been continuously working towards reducing the size of technological components. Room-sized computers to laptops that are slimmer than a pane of glass? It’s done. Huge bulky telephones to smartphones that can fulfil a lot more? A thing of the past. The real question is, to what extent can all this [...]
You have witnessed a variety of nano-devices that were designed for tasks including delivering medicines within the body. All of them used to move in a variety of ways. However, the latest nano-device is a four-legged nano-robot that will be able to walk up to its target. The technology was first developed by Asst. [...]
To take his fledgling lab to new heights, Liangfang Zhang hatched a plan that he considered brilliant in its simplicity. It involved procedures that many of his peers found a little out there. But if he could make his idea work, it would clear a major hurdle to safely ferry therapies through the body [...]
Netra Rajesh is an undergraduate Engineering Science student specializing in Biomedical Systems Engineering. She is currently on her Professional Experience Year (PEY) at the Massachusetts Institute of Technology where her research lies at the crossroads of nanomedicine, medical engineering, and oncology. At 14, Rajesh designed an experiment and attempted to conduct the research in [...]
Nearly half of the companies in Europe that call themselves AI start-ups don't in fact use artificial intelligence, a new report found. The research, published Tuesday by London-based venture capital firm MMC Ventures, found no evidence that artificial intelligence was an important part of the products offered by 40 percent of Europe's 2,830 AI [...]
A new quantum sensor developed by researchers at the University of Waterloo's Institute for Quantum Computing (IQC) has proven it can outperform existing technologies and promises significant advancements in long-range 3D imaging and monitoring the success of cancer treatments (Nature Nanotechnology, "Tapered InP nanowire arrays for efficient broadband high-speed single-photon detection"). The sensors are [...]
Every year, more than 18 million people around the world are told, "You have cancer." In the U.S., nearly half of all men and more than one-third of women will develop some kind of cancer during their lifetimes, and 600,000-plus die from it annually. Despite the billions of dollars and countless new treatments that [...]
Summary: Researchers use nanotech to enhance vision in mice, enabling them to see infrared light as well as visible light. Source: Cell Press. Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of [...]
