Mesoporous silica honeycomb carries antibodies, kills tumors

By / May 26, 2010

Like bees and their honeycomb, a team of PNNL and University of Washington scientists have figured out a way to pack tumor killing antibodies into the cavities of porous silica particles, hopefully creating a superior transport system for anti-cancer agents. They have demonstrated that they can embed antibodies into the structure of chemically modified silica…

Monday materials mind candy: ‘Printed’ origami ceramic structures

By / April 19, 2010

As you can see above, ACerS Fellow Jennifer Lewis and her team at the University of Illinois at Urbana-Champaign have figured out how to make intriguing and beautifully simple (yet complex) origami structures by bending and folding planar lattices. The lattices are made by extruding “inks” of ceramic, metal or polymeric materials using a precise,…
