New Models to Study Nanoparticle Interaction with Cell Membranes

CoverIssueAn article by Melby et al. will soon be featured in the journal Environmental Science Nano. The paper focuses on the development of models for cell surfaces for the purpose of studying how engineered nanoparticles interact with organisms. The authors show that by incorporating domains differing in fluidity in model cell membranes (lipid bilayers), the attachment of positively charged nanoparticles is increased over the case where such domains are absent. The lead author is Eric Melby (Ph.D. candidate in Environmental Chemistry and Technology in Joel Pedersen’s group; M.S., Soil Science, 2010 under Doug Soldat). A lay description of the study can be found on their blog site:
