Chemical Engineers Design Nanoparticles to Target Cancer Tumors

May 02, 2011. By Douglas B. Clark
Chemical engineers at MIT have designed a nanoparticle that could one day be used to target cancerous tumors, reports MIT News. The particle, which could be used to deliver drugs to tumors, takes advantage of the fact that tumors generally exhibit higher acidity that healthy tissue. Like other drug-delivering nanoparticles, the researchers' creation is covered in a polymer that keeps it from degrading in the bloodstream. These particles, however, drop their protective polymer cloak once exposed to the higher acidity of a tumor. Underneath the protective coating is another layer that can penetrate the tumor. The particles are described in detail in the journal ACS Nano.

Intel Employees Grow Algae By Harnessing their Arizona Chip Fab's Carbon Dioxide

Intel's on an roll. Just in time for Earth Day, their huge, Arizona chip fab was the first semiconductor manufacturing company to receive LEED certification for its entire campus. The improvements that led to the new LEED classification came from Intel employees, and, as the whole idea of sustainability gains momentum at Intel, many new ideas are starting to come from outside the research lab.
