Bloodstream

According to the CDC, every year 60,000-100,000 people die in the US alone from blood clots formed from conditions known as deep vein thrombosis or pulmonary embolisms. Now, a new patch developed by researchers in North Carolina could help battle these life-threateners in a novel way.

Science fiction is fast becoming reality, with scientists in South Korea developing an astonishingly fast-moving remote-controlled microrobot designed to travel through the human bloodstream to deliver treatment directly to the organs that need it.

Finger-prick blood tests are currently an unpleasant necessity for diabetics. Perhaps before too long, however, the blood glucose information gathered in those tests could be attained using something much more fun and painless than a lancet – a temporary tattoo.

Researchers from the Max Planck Institute for Intelligent Systems, in Germany have been experimenting with real micro-sized robots that literally swim through your bodily fluids with the idea of delivering drugs or other medical relief in a highly-targeted way.

Not much is known about how tumor cells travel to different parts of the body, a process known as metastasis. But engineers have created a device that is offers a new perspective, allowing researchers an up-close look at the cells as they spread, potentially unearthing new methods of treatment.

Scientists at at the University of California, San Diego have created a 3D-printed liver-like device that's claimed capable of safely detoxifying blood.

Figuring out how much medication a patient should be taking can be a tricky business. With that in mind, scientists have developed an implantable device that provides real-time readings on how much medication is currently in a person's bloodstream.

Scientists have developed nanosponges that are capable of neutralizing toxins in the bloodstream.

Scientists have developed injectable microparticles containing oxygen gas, that could be used to raise blood oxygen levels when a patient's lungs aren't working or their airway is blocked.

Engineers at Stanford University have demonstrated a tiny, wirelessly powered, self-propelled medical device that could be navigated through the bloodstream.

A new device uses light to non-invasively monitor blood oxygenation in the brains of stroke patients.

Scientists have created a "microvascular stamp," that causes new blood vessels to grow in directed patterns on biological tissue.
