Hydrophilic Inorganic Macro-Ions in Solution: Unprecedented Self-Assembly Emerging from Historical "Blue Waters"  Tianbo Liu, Ekkehard Diemann, and Achim Müller
The behavior of supramolecular structures in solution is different from that of simple ions, polymers, surfactant micelles, and colloids. New research involving polyoxometalates, which are fully hydrophilic but tend to self-associate into macro-ionic structures, may change our understanding of inorganic ionic solutions.

Hands-on Classroom Photolithography Laboratory Module To Explore Nanotechnology  Scott J. Stelick, William H. Alger, Jesse S. Laufer, Anna M. Waldron, and Carl A. Batt
Teaching nanotechnology in the high school and undergraduate environment is a challenge given the typical expense of instruments used to create micro- and nano-sized devices. To meet this challenge, a portable optical reduction stepper was designed, fabricated, and optimized for use in classrooms. This unique system was designed to provide a safe, hands-on experience for students to create microscale circuits using photolithography. Students are able to design, fabricate, and test a circuit with dimensions as small as 100 mm.

A Supramolecular Approach to Medicinal Chemistry: Medicine Beyond the Molecule  David K. Smith
This article emphasizes a conceptual view of medicinal chemistry, which has important implications for the future, as the supramolecular approach to medicinal-chemistry products outlined here is rapidly allowing nanotechnology to converge with medicine. In particular, this article discusses recent developments including the rational design of drugs such as Relenza and Tamiflu, the mode of action of vancomycin, and the mechanism by which bacteria develop resistance, drug delivery using cyclodextrins, and the importance of supramolecular chemistry in understanding protein aggregation diseases such as Alzheimer's and CreutzfieldJacob.
