A recent paper from the Pinkhassik group was featured on the cover of Chemistry – A European Journal (Chem. Eur. J. 2016, 22(40), 14137-14140). The cover image illustrates new hybrid nanomaterials, rotaxane-like structures threaded through the pores of hollow porous nanocapsules. These structures may lead to the creation of complex nanoscale cell-mimicking devices. Dr. Sergey Dergunov (UConn) and Nasim Ehterami (Saint Louis University) contributed to this work.
