Chapel Hill, N.C. – January 7, 2008 – New polymerization technology may one day take the pain out of injections and blood draws. A team of researchers at the University of North Carolina and Laser Zentrum Hannover have recently used two-photon polymerization to create hollow needles so fine patients wouldn’t feel them piercing their skin. Clustered together on a patch, these microneedles can deliver drugs or draw blood efficiently as standard hypodermic needles. These findings are reported in the International Journal of Applied Ceramic Technology.
