What is the origin of chirality in the cholesteric phase of virus suspensions ? [PDF]
Phys. Rev. Lett. 90.198302. 2003, 2003 We report a study of the cholesteric phase in monodisperse suspensions of the rod-like virus fd sterically stabilized with the polymer polyethylene glycol (PEG). After coating the virus with neutral polymers, the phase diagram and nematic order parameter of the fd-PEG system then become independent of ionic strength.

Phosphorus Contamination in Polyethylene Glycol [PDF]
Plant Physiology, 1978 Concentrations of Fe, Mn, Cu, Zn, Ca, Mg, K, and P were examined in untreated and ion exchange resin-treated solutions of polyethylene glycol, molecular weight 3000 to 3700, polyethylene glycol (PEG 4000). Relatively high levels of P were found in untreated PEF-4000 solutions.

Atomic force microscopy (AFM) study of thick lamellar stacks of phospholipid bilayers [PDF]
Phys. Rev. E 77, 021905 (2008) (8 pages)., 2007 We report an Atomic Force Microscopy (AFM) study on thick multi lamellar stacks of approx. 10 mum thickness (about 1500 stacked membranes) of DMPC (1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine) deposited on silicon wafers. These thick stacks could be stabilized for measurements under excess water or solution.

Microscale adhesion patterns for the precise localization of amoeba [PDF]
, 2009 In order to get a better understanding of amoeba-substrate interactions in the processes of cellular adhesion and directional movement, we engineered glass surfaces with defined local adhesion characteristics at a micrometric scale. Amoeba (Dictyostelium dicoideum) is capable to adhere to various surfaces independently of the presence of extracellular ...
