Monodisperse, surfactant-free polymer spheres for use as colloidal crystal templates can be easily obtained in reasonably large quantities. Typical synthesis methods for poly(methyl methacrylate) (PMMA) and poly(styrene) (PS) by emulsifier free emulsion polymerization are described below and yield spheres several
Selenium is an essential trace element. It is a necessary dietary constituent of at least 25 human selenoproteins and enzymes containing selenocysteine. Additionally, as selenium is a semiconductor and photoelectrically active, it has more advanced applications such as xerography and
Nanodisc technology offers a means to overcome some of the challenges associated with solubilizing membrane proteins. Nanodisc technology is applicable to a wide variety of membrane proteins and protein classes.
