A MagnetoSperm in action

When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm.  Read More

Scientists at the University of Texas have built and tested what appears to be the world's...

Scientists at the Cockrell School of Engineering at the University of Texas have built and tested what appears to be the world's smallest, fastest, and longest-running nanomotor yet – so small that it could fit inside a single cell. The advance could be used to power nanobots that would deliver specific drugs to individual living cells inside the human body.  Read More

'Juanita Knits the Planet' found its way onto the hair not for its compelling narrative ar...

Advances in technology have given rise to an abundance of ways to share our stories. There's messaging services for the short and sharp, blogging platforms for the long-winded and, as it happens, single strands of human hair for microscopic comic strips. Created for the Exceptional Hardware Software Meeting (EHSM) in Germany next month, "Juanita Knits the Planet" is the world's smallest comic strip, detailing a day in the life of Juanita, a ten micron-tall girl-turned-robot.  Read More

The team constructed a lipid-coated nanodevice that survived the mouse immune system due t...

Researchers from Harvard University's Wyss Institute for Biologically Inspired Engineering have developed a cloaked DNA nanodevice capable of evading the body's immune defenses. The design was inspired by real world viruses and could be used to diagnose cancer and better target treatments to specific areas of tissue.  Read More

The magazine cover is so small that 2,000 can fit on a grain of salt

IBM has unveiled the world’s smallest magazine cover at the USA Science and Engineering Festival in Washington, DC. Certified by the Guinness Book of World Records, the micro magazine is a reproduction of the cover of the March 2014 issue of National Geographic Kids and is many times smaller than a grain of salt at just 11 × 14 micrometers. Why, you ask? The tiny cover was created to demonstrate potential of a new nano-scale manufacturing technology, as well to encourage young people’s interest in science and technology.  Read More

Examples of the microparticles, shown here much larger than actual size

There's now yet another potential weapon in the war against counterfeiting. Scientists at MIT have developed tiny color-striped microparticles that could be used to verify the authenticity of currency, medication, consumer goods, or almost anything else.  Read More

Israeli startup StoreDot has showcased a prototype of a new smartphone battery that can re...

Today at Microsoft’s Think Next symposium in Tel Aviv, Israeli startup StoreDot has demonstrated the prototype of a nanodot-based smartphone battery it claims can fully charge in just under 30 seconds. With the company having plans for mass production, this technology could change the way we interact with portable electronics, and perhaps even help realize the dream of a fast-charging electric car.  Read More

A rendering of a nanoparticle trapped in a laser and in thermal non-equilibrium (Image: Iñ...

It may be a little late for April Fool’s, but your skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the flow of entropy and heat in, it was believed, any situation. Specifically, researchers from three universities theoretically proposed then demonstrated that a nanoparticle in a state of thermal non-equilibrium does not always behave as larger particles might under the same conditions, with implications for various fields of research.  Read More

One of KAIST's silver nanowire fingerprints

The counterfeiting of high-end products is a growing problem, and has led to the development of countermeasures such as invisible woven patterns, butterfly wing-inspired printing techniques, and even synthetic DNA. One of the drawbacks of some of these approaches, however, is the fact that implementing them can be quite a complex process. Now, a team from the Korea Advanced Institute of Science and Technology (KAIST) has come up with something simpler – tiny jumbles of nanowires that form item-specific "fingerprints."  Read More

Newly-developed nasal spray vaccines offer some key advantages over injections  (Photo: Sh...

Vaccines save lives, but sometimes they fail to reach the people who need them most, in parts of the developing world. A research team from Iowa State University is currently developing a new generation of vaccines that uses nanotechnology, and is delivered in spray form. One of the advantages of this new type of vaccine is that is can increase access to people living in remote areas because it requires no refrigeration and is simpler to administer.  Read More
