"Self-Propelled Micromotors Take Their First Swim in the Body"
In recent years, researchers have designed microsized motors that react with chemicals around them in solution to produce jets of bubbles, propelling them forward or actuating moving parts. These particles can swim or perform tasks, such as sorting cells in tubes of blood. But so far, no one had tested the devices inside an animal. Joseph Wang, a nanoengineer at the University of California, San Diego, says one major challenge has been the fuel that the motors react with to zip around.

"Scientists implant tiny robots inside live mice"
Can robots travel inside living animals? It sounds like science fiction, but scientists have just made it a reality by implanting tiny nano-robots inside living mice. Researchers from the Department of Nanoengineering at the University of California, San Diego, published their report on the first successful tests of implanting micro robots designed to disperse drugs within a body, reports SmithsonianMag.com.

"Micromotors Take Their First Swim In The Body"
The idea sounds like something out of a science-fiction novel: Tiny medical machines zooming around the body delivering drugs, taking tissue samples, or performing small surgical repairs. But, now, for the first time, researchers have demonstrated a simple micromotor that can propel itself inside the body (ACS Nano 2014, DOI: 10.1021/nn507097k). When introduced into a mouse?s stomach, the micromotor swims to the stomach lining and delivers cargo.

"STICK-ON TATTOO MEASURES BLOOD SUGAR WITHOUT NEEDLES"
Diabetics often prick their fingers up to eight times a day to check their blood sugar. Researchers have long looked for a solution that provides constant monitoring without being so invasive, and researchers at the University of California San Diego have come up with a new needle-free design that could turn out to be less painful, yet just as effective, as the finger-prick method. The UCSD team printed electrodes onto standard temporary tattoo paper and paired it with a sensor.

"Scientists Test Out Tiny Robots Meant to Travel Inside a Human Body"
Roobots aren't just taking over the skies--they're taking over our bodies. Or, at least, they could be soon. A team of researchers from the University of California has recently published a study describing the first successful tests, within a living creature, of nano-robots intended to carry and disperse drugs within the body.
"The First Demonstration Of Self-Propelled Nanobots In A Living Animal"
Researchers from the University of California have developed acid-fueled micro-machines capable of traveling and delivering cargo directly inside a living creature. It's a breakthrough that's expected to significantly advance the field of medical nano-robotics. Scientists have developed drug-delivering micro-machines before, but these systems were only tested under in vitro conditions (i.e., cell cultures outside the body).
"Micro-machines journey inside animal for first time"
The tiny devices delivered a cargo of nano-particles into the stomach lining of a mouse. The research by scientists at the University of California is published in the journal ACS Nano. Medical applications for micro-machines include the release of drugs into specific locations within the body. But until now, they have only been tested in laboratory cell samples. A team led by Professors Liangfang Zhang and Joseph Wang from UC, San Diego, fed the tiny motors to mice.
"Engineers create a temporary tattoo that tests blood sugar"
Amay Bandodkar, a researcher at the University of California, San Diego, has created a flexible sensor that uses a mild electrical current to measure glucose levels in a person's body. Measuring blood sugar levels multiple times a day is vital for diabetes patients because it shows how well their body is managing their disease as well as the dose of insulin they require, if they need any at all.
"Temporary tattoo could let diabetics monitor glucose levels without jabbing themselves"
Developed by a team led by University of California, San Diego grad student Amay Bandodkar, the flexible prototype device consists of precisely-patterned electrodes printed on temporary tattoo paper. After the tattoo is applied to the patient, a "very mild" electrical current is also applied to their skin.

"This Tattoo for Diabetics Might Mean the End of Finger Pricking"
Diabetics engage in a painful ritual every day, often several times: pricking their fingers with a spring-loaded needle to test the glucose in their blood. But that ritual could soon be put to rest, and replaced by a small patch designed to extract and measure blood-sugar levels. Flexible, easy to apply, and inconspicuous, the next-generation wearable is a promising step toward noninvasive monitoring of diabetes

"Mice are first pioneers of medical micromissiles"
It's a small but significant step for microscopic machines. Tiny motors have journeyed through a living animal for the first time, delivering a test cargo of gold nanoparticles directly into the lining of a mouse's stomach. Micromachines promise to revolutionise the diagnosis and treatment of certain medical conditions. Tiny spiders could repair blood vessels, for instance, while microrobots could swim through the bloodstream and build medical devices at sites of disease or injury.
"A 'tattoo' may end fingerpricks for diabetics"
Scientists at the University of California, San Diego, developed a thin and flexible patch resembling a temporary tattoo that they say can continuously monitor glucose levels in the blood without puncturing or irritating the skin. The sensor is a clear patch affixed with two small electrodes and an enzyme that reacts with glucose. The researchers ran a mild electrical current through the electrodes to drive glucose to the surface of the skin where it reacted with the enzyme on the patch.

"Temporary Tattoo Monitors Blood Glucose Levels"
Scientists from the University of California, San Diego, have developed and tested a tiny stick-on temporary tattoo that painlessly extracts glucose and monitors its levels in the body. It works by gently drawing glucose from between cells to the surface of the skin where it can then be measured by in-built sensors. Not only is the gadget non-invasive and discreet, it?s extremely cheap--costing just a few cents--and works just as well as the dreaded finger prick tests.
"A Rub-On Tattoo for Diabetics Could Mean the End of Finger Pricking"
Pricking your finger for a blood glucose test will never, ever be fun. Thankfully, scientists have been hard at work on a bloodless and needleless alternative: a rub-on temporary tattoo that, as weird as it sounds, gently sucks glucose through the surface of the skin. The thin, flexible device created by nanoengineers at UCSD is based on the much bulkier GlucoWatch, a now-discontinued wristband that worked through the same glucose-sucking principal.

A multi-disciplinary engineering team at the University of California, San Diego, have developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90% of the sunlight it captures. It is said the new material can also withstand temperatures greater than 700C and survive many years outdoors in spite of exposure to air and humidity.
