SSTs – self-assembling synthetic DNA “building blocks”

By Damir Beciri
31 May 2012

sst-dna-structuresIn 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… »

Hydrogel that can self-heal in aqueous environment

By Damir Beciri
12 March 2012

ucsd-self-healing-hydrogel-1University 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,… »

One Comment29 December 2011

burn-hydrogel-1Johns 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 getting closer to artificial cartilage creation

By Damir Beciri
10 December 2011

knee-cartilage_0Researchers 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… »

CATRA – a new affordable technology for cataract diagnose

By Rob Aid
4 Comments1 July 2011

catra-prot-cellphoneCataracts 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… »
