Nanomaterials and nanoparticles: Sources and toxicity Tập 2 Số 4 - Trang MR17-MR71 - 2007
Cristina Buzea, Ivan I. Pacheco, Kevin Robbie
This review is presented as a common foundation for scientists interested in nanoparticles, their origin, activity, and biological toxicity. It is written with the goal of rationalizing and informing public health concerns related to this sometimes-strange new science of “nano,” while raising awareness of nanomaterials’ toxicity among scientists and manufacturers handling them. We show tha...... hiện toàn bộ
Polymer brushes and self-assembled monolayers: Versatile platforms to control cell adhesion to biomaterials (Review) Tập 4 Số 2 - Trang FA3-FA16 - 2009
Jenny E. Raynor, Jeffrey R. Capadona, David M. Collard, Timothy A. Petrie, Andrés J. Garcı́a
This review focuses on the surface modification of substrates with self-assembled monolayers (SAMs) and polymer brushes to tailor interactions with biological systems and to thereby enhance their performance in bioapplications. Surface modification of biomedical implants promotes improved biocompatibility and enhanced implant integration with the host. While SAMs of alkanethiols on gold su...... hiện toàn bộ
Molecular-scale structural and functional characterization of sparsely tethered bilayer lipid membranes Tập 2 Số 1 - Trang 21-33 - 2007
Duncan J. McGillivray, Gintaras Valinčius, David J. Vanderah, Wilma Febo‐Ayala, John T. Woodward, Frank Heinrich, John J. Kasianowicz, Mathias Lösche
Surface-tethered biomimetic bilayer membranes (tethered bilayer lipid membranes (tBLMs)) were formed on gold surfaces from phospholipids and a synthetic 1-thiahexa(ethylene oxide) lipid, WC14. They were characterized using electrochemical impedance spectroscopy, neutron reflection (NR), and Fourier-transform infrared reflection-absorption spectroscopy (FT-IRRAS) to obtain functional and st...... hiện toàn bộ
Settlement and adhesion of algal cells to hexa(ethylene glycol)-containing self-assembled monolayers with systematically changed wetting properties Tập 2 Số 4 - Trang 143-150 - 2007

Protein resistance of self-assembled monolayers (SAMs) of hexa(ethylene glycols) (EG6) has previously been shown to be dependent on the alkoxyl end-group termination of the SAM, which determines wettability [S. Herrwerth, W. Eck, S. Reinhardt, and M. Grunze, J. Am. Chem. Soc. 125, 9359 (2003)]. In the present study, the same series of hexa(ethylene glycols) was used to examine the correlat...... hiện toàn bộ
Surface Functionalized Nanofibrillar Cellulose (NFC) Film as a Platform for Immunoassays and Diagnostics Tập 7 Số 1 - 2012
Hannes Orelma, Ilari Filpponen, Leena‐Sisko Johansson, Monika Österberg, Orlando J. Rojas, Janne Laine
We introduce a new method to modify films of nanofibrillated cellulose (NFC) to produce non-porous, water-resistant substrates for diagnostics. First, water resistant NFC films were prepared from mechanically disintegrated NFC hydrogel, and then their surfaces were carboxylated via TEMPO-mediated oxidation. Next, the topologically functionalized film was activated via EDS/NHS chemistry, an...... hiện toàn bộ
Protein adsorption on and swelling of polyelectrolyte brushes: A simultaneous ellipsometry-quartz crystal microbalance study - 2010
Eva Bittrich, Keith B. Rodenhausen, Klaus‐Jochen Eichhorn, Tino Hofmann, M. Schubert, Manfred Stamm, Petra Uhlmann
With a coupled spectroscopic ellipsometry-quartz crystal microbalance with dissipation (QCM-D) experimental setup, quantitative information can be obtained about the amount of buffer components (water molecules and ions) coupled to a poly(acrylic acid) (PAA) brush surface in swelling and protein adsorption processes. PAA Guiselin brushes with more than one anchoring point per single polyme...... hiện toàn bộ
Advanced nanostructures for the control of biofouling: The FP6 EU Integrated Project AMBIO Tập 3 Số 1 - Trang IR1-IR5 - 2008
Axel Rosenhahn, Thomas Ederth, Michala E. Pettitt
The colonization of man made structures by marine or freshwater organisms or “biofouling” is a problem for maritime and aquaculture industries. Increasing restrictions on the use of toxic coatings that prevent biofouling, create a gap in the market that requires new approaches to produce novel nonbiocidal alternatives. This review details the systematic strategy adopted by an FP6 EU Integr...... hiện toàn bộ
Formation of supported bacterial lipid membrane mimics Tập 3 Số 2 - Trang FA41-FA50 - 2008
Christoph Merz, Wolfgang Knoll, Marcus Textor, Erik Reimhult
In recent years, a large effort has been spent on advancing the understanding of how surface-supported membranes are formed through vesicle fusion. The aim is to find simple model systems for investigating biophysical and biochemical interactions between constituents of cell membranes and, for example, drugs and toxins altering membrane function. Designing and controlling the self-assembly...... hiện toàn bộ
