In an emerging field of science known as DNA nanotechnology, DNA is being explored for use as a material that can be used to build small and programmable structures. Researchers at the Wyss Institute have used short synthetic strands of DNA to developed interlocking DNA “building blocks” able to form complex nanostructures. Named single-stranded tiles… »
Scientists at the Stanford University School of Medicine have devised a system that could ultimately be used to restore sight to people who have lost vision due to certain types of degenerative eye diseases. Although their results were achieved on rat retinas, the scientists are now testing the system in live rats, taking both physiological… »
An interdisciplinary team of engineers at the University of Arkansas developed e-Nanoflex Sensor System – a wireless health-monitoring textile-based sensors that can be integrated into conventional sports bra or a vest. Since the monitored information can be sent in real time to a physician, hospital or the wearer’s smartphone, the technology enables easier monitoring of… »
University of California, San Diego bioengineers have developed a smart and easy-to-synthesize self-healing hydrogels that consist of linked chains of polymer molecules which are capable to self-heal in aqueous environment. This jello-like material’s ability to self-heal, bind in seconds and form a bond strong enough to withstand repeated stretching could find uses in biology, medicine,… »
Johns Hopkins researchers have developed a simple wound dressing that included a specially designed hydrogel – a water-based, three-dimensional framework of polymers – that promotes the formation of new blood vessels and skin, including hair follicles. It could lead to greatly improved healing for injured soldiers, home fire victims and other people with third-degree burns…. »
Researchers at the Case Western Reserve University are one step closer to create implantable replacement cartilage. The method allows cartilage to form from patient’s own stem cells without lengthy culture time before the implantation. The technology could solve cartilage problems which occur after sports injuries and accidents, as well as in cases of osteoarthritis which… »
Surgery performed on eyes, such as retina repairs or treating a detached retina, demands high precision. Eindhoven University of Technology (TU/e) researcher has developed a smart eye-surgery robot that allows eye surgeons to operate with increased ease and greater precision. The system also extends the effective period during which ophthalmologists can carry out these delicate… »
Cataracts are the leading cause of blindness worldwide, with over 48% of world blindness caused by age related cataracts. Existing diagnostic methods require Slit-lamps, which require a trained physician to interpret the results and aren’t affordable. Researchers from MIT have developed a simple device that can clip onto an ordinary smartphone or a tablet and… »
