Tunable Microsieves
February 17, 2015 | Terry Sharrer
Using synthetic lipid spheres and DNA ligands, biochemists at Cambridge University have developed what they believe to be a new kind of biosensor, though actually they are tunable microsieves which could be used for drug delivery or in controllable scaffolds for cell regeneration. In response to a rise in temperature, the material contracts (instead of expands) and becomes more porous. Replacing the ligands with antibodies raised the possibility of these sieves becoming molecular sensors. MORE
