Zurich Biomaterials LLC

zurich biomaterials llc is a medtech start-up based in zurich, switzerland. two of the four founders, prof. wendelin stark (eth zurich) and prof. patrick schmidlin (unizh) have invented a new bone regeneration material in 2007. they named it bonewool®. in 2013 zurich biomaterials llc has acquired the exclusive patent license from the technology transfer office of eth zurich. bonewool® - the future implant material for bone regeneration. today, most of the surgical operations to repair fractures and bone defects are performed using autografts and allografts despite their limitations in terms of availability, donor-site morbidity and potential negative immune responses. this has triggered research to find fully synthetic alternative bone substitute materials. the invention of bonewool® relates to the preparation of a new and advanced implant material consisting of a biodegradable polymer such as a plga with up to 40wt% of amorphous tricalcium phosphate (atcp) nanoparticles incorporated i
