Blood

The HemoLink device can draw enough blood for certain routine tests without the need for n...

Though the pain they cause is minor and fleeting, a lot of people still find something pretty unsettling about needles. When it comes to conducting a routine blood test, US-based company Tasso Inc. believes that these unpleasant pricks can be removed from the equation completely. Its ping pong ball-sized HemoLink blood sampler can be operated by the patient at home, and needs only to be placed against the skin of the arm or abdomen for two minutes to do its job.  Read More

LabDisk is a device for detecting multiple diseases quickly and non-invasively

Typically, tests for diseases must be done one disease at a time, and can take days to be processed through a lab. A new device developed in an EU project, however, can test for several diseases at the same time and provide results within an hour. The LabDisk is designed for use in Africa.  Read More

An algorithm developed by University of Warwick researchers can detect and differentiate b...

While blood tests are used to rule out other forms of arthritis, the diagnosis of osteoarthritis (OA) generally relies on physical symptoms, with X-rays or MRI scans used for conformation if required. But researchers at the University of Warwick in the UK have identified a biomarker for OA that could lead to a blood test that could diagnose it, and rheumatoid arthritis (RA), years before physical symptoms present themselves.  Read More

A 3D rendering of a blood clot forming, with PolySTAT (in blue) binding strands of fibrin ...

With uncontrolled bleeding the major cause of deaths on the battlefield, researchers at the University of Washington have developed an injectable polymer that could stem bleeding and provide extra time to get the injured to medical care. Called PolySTAT, the new polymer stems blood loss by strengthening blood clots.  Read More

The new tissue system contains platelet-producing blood cells called megakaryocytes (seen ...

Researchers at Tufts University School of Engineering and the University of Pavia (Italy) have developed a three-dimensional tissue made from porous silk, that’s capable of producing platelets for clinical use. The development is expected to have a significant impact on treatment of blood diseases.  Read More

The MIT testing device could supply a result in around 10 minutes via a color coding syste...

Researchers from MIT claim to have developed an easy-to-use blood test that can be applied in the field, allowing for the screening of multiple diseases at once. The test is said to provide results in around 10 minutes, and could be instrumental in stopping the epidemic spread of fatal diseases such as Ebola.  Read More

The new nanoparticles that help break up blood clots feature an iron oxide core (red), a c...

Tissue plasminogen activator (tPA) is a drug commonly used by surgeons to bust open blood clots in a patient's bloodstream, but it does have its limitations. Once injected, there's no guarantee it will reach the site of the blood clot, and even then, having it arrive in the correct dosage can be tricky, with the risk of hemorrhage a very real possibility. Researchers have now found that using a new type of magnetic nanoparticle to deliver the drug offers a much more efficient journey to the site, promising to destroy blood clots 100 to 1,000 times faster and aid significantly in the prevention of heart attacks and strokes.  Read More

The robotic sock developed at the National University of Singapore to treat Deep Vein Thro...

The onset of Deep Vein Thrombosis (DVT), whereby a clot forms in the veins and obstructs blood flow, is a legitimate concern for people unable to move their legs. The condition can become truly life-threatening if the clot finds its way into the pulmonary artery, which carries deoxygenated blood to the lungs. Looking to mitigate the dangers of this condition, researchers have developed a specialty sock inspired by the tentacle movements of coral that is designed to stimulate blood circulation through the body.  Read More

A sensor made from organic materials can be worn like a Band-Aid to track blood oxygen lev...

Maintaining a steady blood oxygen level is critical for the body to stave off breathing problems and organ trouble. For those needing to keep a close eye on things, there's no shortage of monitoring systems and dedicated pulse oximeters available, but these can be somewhat unwieldy. Scientists at the University of California (UC) Berkeley are looking to make the process a little less cumbersome with the development of a thin, blood-oxygen sensor that can be worn much like a Band-Aid.  Read More

Artist's rendering of synthetic platelets that mimic, and outperform, natural platelets (I...

The skin is the body's first line of defense against infection. And when this barrier is broken, or an internal organ is ruptured, it is the process of coagulation, or clotting, which relies largely on blood cells called platelets, that seals the breach and stems the flow of blood. Researchers at UC Santa Barbara have now synthesized nanoparticles that mimic the form and function of platelets, but can do more than just accelerate the body's natural healing processes.  Read More
