Bivalent kinetic binding model to surface plasmon resonance studies of antigen-antibody displacement reactions

Dagmar Gelinsky-Wersing, Wolfram Wersing, Wolfgang Pompe

Analytical Biochemistry > 2017 > 518 > C > 110-125

Molecular and functional analysis of small molecule binding to protein can provoke insights into cellular signaling and regulatory systems as well as facilitate pharmaceutical drug discovery. In label free small molecule detection the displacement assay format can be applied. This is beneficial because displacement of high molecular weight receptors is detected instead of low molecular weight ligand...

The Role of Osteocalcin in the Remodeling of Biomimetic Hydroxyapatite-Collagen Materials for Bone Replacement

Wolfgang Pompe, Katharina Flade, Michael Gelinsky, Birgit Knepper-Nicolai, więcej

Mathematics and Biosciences in Interaction > Function and Regulation of Cellular Systems > Cellular Materials: Mechanics and Motility > 177-183

The increasing interest of materials scientists in biomineralisation phenomena is caused by the option of new biomimetic processing routes for materials with unusual structures and properties. Among them new biomaterials for application in medicine are of great interest. In this paper we will discuss a new biomimetic approach for manufacturing of bone implants based on hydroxyapatite (HAP)-collagen...

Colorimetric As (V) detection based on S-layer functionalized gold nanoparticles

Mathias Lakatos, Sabine Matys, Johannes Raff, Wolfgang Pompe

Talanta > 2015 > 144 > C > 241-246

Herein, we present simple and rapid colorimetric and UV/VIS spectroscopic methods for detecting anionic arsenic (V) complexes in aqueous media. The methods exploit the aggregation of S-layer-functionalized spherical gold nanoparticles of sizes between 20 and 50nm in the presence of arsenic species. The gold nanoparticles were functionalized with oligomers of the S-layer protein of Lysinibacillus sphaericus...

Biological activity and mechanical stability of sol–gel-based biofilters using the freeze-gelation technique for immobilization of Rhodococcus ruber

Angela Pannier, Martin Mkandawire, Ulrich Soltmann, Wolfgang Pompe, więcej

Applied Microbiology and Biotechnology > 2012 > 93 > 4 > 1755-1767

Biofilters with long lifetime and high storage stability are very important for bioremediation processes to ensure the readiness at the occurrence of sudden contaminations. By using the freeze-gelation technique, living cells can be immobilized within a mechanically and chemically stable ceramic-like matrix. Due to a freeze-drying step, the embedded microorganisms are converted into a preserved form...

Friction-Controlled Traction Force in Cell Adhesion

Tilo Pompe, Martin Kaufmann, Maria Kasimir, Stephanie Johne, więcej

Biophysical Journal > 2011 > 101 > 8 > 1863-1870

The force balance between the extracellular microenvironment and the intracellular cytoskeleton controls the cell fate. We report a new (to our knowledge) mechanism of receptor force control in cell adhesion originating from friction between cell adhesion ligands and the supporting substrate. Adherent human endothelial cells have been studied experimentally on polymer substrates noncovalently coated...

Engineering of self-assembling proteins for biosensing applications

Melinda Varga, Gerhard Roedel, Wolfgang Pompe

2011 11th IEEE International Conference on Nanotechnology > 1602 - 1606

2011 IEEE 11th International Conference on Nanotechnology (IEEE-NANO)

The ability of isolated bacterial cell surface layer (S-layer) protein subunits to self-assemble into protein layers on solid surfaces makes them an almost ideal biological template for sensor oriented applications. Here, we used this remarkable property of the recombinant S-layer protein of Sporosarcina ureae bacterium to display streptavidin in defined order and orientation into two dimensional,...

A microkinetic model of ammonia decomposition on a Pt overlayer on Au(111)

Karsten Rasim, Manfred Bobeth, Wolfgang Pompe, Nicola Seriani

Journal of Molecular Catalysis. A, Chemical > 2010 > 325 > 1-2 > 15-24

Ammonia decomposition is important for a series of technological applications. For developing efficient catalysts for this reaction, basic understanding of underlying mechanisms is fundamental. We have investigated ammonia decomposition on platinum (111) and (100) surfaces, and on a platinum overlayer on a (111) gold substrate within a microkinetic model. The kinetic parameters in the corresponding...

Film bulk acoustic resonators for DNA and protein detection and investigation of in vitro bacterial S-layer formation

Martin Nirschl, Anja Blüher, Christiane Erler, Beate Katzschner, więcej

Sensors & Actuators: A. Physical > 2009 > 156 > 1 > 180-184

We report investigations on the use of film bulk acoustic resonators for the label-free, multiplexed biosensing of DNA and proteins. The used acoustic resonators were operated in shear mode at about 800MHz. From the measured changes of frequency and in dissipation, the mass and the viscoelasticity of biomolecular films formed at the top electrode of the device could be derived, respectively. A mass...

Catalytic Carbon Monoxide Oxidation Using Bio-Templated Platinum Clusters

Regina Hüttl, Frank Ullrich, Gert Wolf, Alexander Kirchner, więcej

Catalysis Letters > 2009 > 132 > 3-4 > 383-388

The catalytic properties of highly dispersed, bacterial surface layer supported nanoscale platinum clusters immobilized at alumina particles are studied with respect to carbon monoxide oxidation. Compared to samples prepared from platinum impregnated alumina, the templated metal clusters are catalytically active at lower temperatures. The catalytic behaviour of the samples is discussed with respect...

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology > 2008 > 105 > 3 > e9-e14

Calcium phosphates are clinically established as bone defect fillers. They have the capability of osseoconduction and are characterized by a slow resorption process. The present study evaluated the suitability of a newly developed calcium phosphate cement modified with collagen type I.The modified cement paste was inserted in differently designed defects of 10 minipigs. Further, an alveolar ridge...

Ab initio study of element segregation and oxygen adsorption on PtPd and CoCr binary alloy surfaces

Arezoo Dianat, Janina Zimmermann, Nicola Seriani, Manfred Bobeth, więcej

Surface Science > 2008 > 602 > 4 > 876-884

The segregation behavior of the bimetallic alloys PtPd and CoCr in the case of bare surfaces and in the presence of an oxygen ad-layer has been studied by means of first-principles modeling based on density-functional theory (DFT). For both systems, change of the d-band filling due to charge transfer between the alloy components, resulting in a shift of the d-band center of surface atoms compared...

Anne Bernhardt, Anja Lode, Sabine Boxberger, Wolfgang Pompe, więcej

Journal of Materials Science: Materials in Medicine > 2008 > 19 > 1 > 269-275

In the field of bone tissue engineering there is a high demand on bone graft materials which promote bone formation. By combination of collagen type I with nanocrystalline hydroxyapatite (HA) we generated a resorbable material which structure and composition is close to those of the extracellular bone matrix. This nanocomposit material was produced in a biomimetic process in which collagen fibril...

Of fine powders, hardmetals, hazard and health risk

Volkmat Richter, Annegret Potthof, Wolfgang Pompe, Michael Gelinsky, więcej

Metal Powder Report > 2007 > 62 > 11 > 12-14

We hear a lot these days about health and safety. Whether it's at work, in the home, driving between the two, or even when we’re taking part in sport or gardening, HSE considerations are ever present. And while it's easy to get cheap laughs at the expense of over-zealous guardians of our ‘best interests’, there is no doubt that health and safety are important topics worthy of close attention. With...
