Hydrogels are highly hydrated polymer networks that can be used in the regenerative medicine field as “scaffolding” for the repair of tissue. A proposed new ASTM standard will provide those working in regenerative medicine with a means of characterizing hydrogels. The work item, ASTM WK21927 , Guide for Characterization of Hydrogels Used in Regenerative Medicine, is under the jurisdiction of…

Each year, approximately 400,000 healthcare workers (HCW) in the United States suffer accidental injury from needles and other medical sharps while tending to patients. These injuries can result from injections, drips, infusions, blood-taking, surgery, biopsy and research, among other causes. Each of these accidents carries a small but documented risk of transmitting more than 60 blood-borne…
