Healing

Danielle Zurovcik SM '07 demonstrates how to use the negative pressure pump to seal an arm...

For some reason, and nobody knows exactly why, the healing process for open wounds can be sped up by applying suction to them under a tightly-sealed bandage. The negative pressure this creates has been benefiting patients for decades but because mechanical pumps are expensive and they need a constant electricity supply the technology is not readily available, often where it is needed most – in the developing world. A newly developed basic negative pressure pump that doesn’t require electricity, is cheap to manufacture, lightweight to transport and can be left in place for days could change that.  Read More

MRSA (methicillin-resistant Staphylococcus Aureus) and other drug-resistant bacteria could...

Low temperature plasma is currently used for the sterilization of surgical instruments. This is because plasma works at the atomic level and is able to reach all surfaces, even the interior of hollow needle ends. Its ability to disinfect is due to the generation of biologically active bactericidal agents, such as free radicals and UV light, which can be delivered to specific locations. Research into how and why these biologically active agents are generated has led to the construction of two prototype devices: one for the efficient disinfection of healthy skin in hospitals and public spaces where bacteria can pose a lethal threat; and another to treat infested chronic wounds.  Read More

Composite drug-releasing fibers that can be used as dissolvable wound dressings

In today’s environment of advanced medical treatments where high success rates are achieved in amazingly delicate operations that until recently weren’t thought possible, a staggering 70 percent of people with severe burns still die from related infections. It is hoped that a revolutionary new wound dressing developed at Tel Aviv University (TAU) could cut that number dramatically.  Read More
