Comparison of nanoparticle-mediated transfection methods for DNA expression plasmids: Efficiency and cytotoxicity

Durán, Maria Carolina; Willenbrock, Saskia; Barchanski, Annette; Müller, Jessika-M.V.; Maiolini, Arianna; Soller, Jan T.; Barcikowski, Stephan; Nolte, Ingo; Feige, Karsten; Murua Escobar, Hugo (London : Biomed Central, 2011)

Background: Reproducibly high transfection rates with low methodology-induced cytotoxic side effects are essential to attain the required effect on targeted cells when exogenous DNA is transfected. Different approaches and ...
Gold Nanoparticle Mediated Laser Transfection for Efficient siRNA Mediated Gene Knock Down

Heinemann, Dag; Schomaker, Markus; Kalies, Stefan; Schieck, Maximilian; Carlson, Regina; Murua Escobar, Hugo; Ripken, Tammo; Meyer, Heiko; Heisterkamp, Alexander (San Francisco, California, US : PLOS, 2013)

Laser based transfection methods have proven to be an efficient and gentle alternative to established molecule delivery methods like lipofection or electroporation. Among the laser based methods, gold nanoparticle mediated ...
In vitro impact of platinum nanoparticles on inner ear related cell culture models

Berger, Elisabeth; Brandes, Gudrun; Reifenrath, Janin; Lenarz, Thomas; Durisin, Martin; Wissel, Kirsten (San Francisco, California, US : PLOS, 2023)

So far, it was supposed that the increase of electrical impedance following cochlear implant (CI) insertion was due to technical defects of the electrode, inflammatory and/or formation of scar tissue along the electrode. ...
Investigation of biophysical mechanisms in gold nanoparticle mediated laser manipulation of cells using a multimodal holographic and fluorescence imaging setup

Kalies, Stefan; Antonopoulos, Georgios C.; Rakoski, Mirko S.; Heinemann, Dag; Schomaker, Markus; Ripken, Tammo; Meyer, Heiko (San Francisco, CA : Public Library of Science (PLoS), 2015)

Laser based cell manipulation has proven to be a versatile tool in biomedical applications. In this context, combining weakly focused laser pulses and nanostructures, e.g. gold nanoparticles, promises to be useful for high ...
Platinum corrosion products from electrode contacts of human cochlear implants induce cell death in cell culture models

Wissel, Kirsten; Brandes, Gudrun; Pütz, Nils; Angrisani, Gian Luigi; Thieleke, Jan; Lenarz, Thomas; Durisin, Martin (San Francisco, CA : Public Library of Science, 2018)

Despite the technological progress made with cochlear implants (CI), impedances and their diagnosis remain a focus of interest. Increases in impedance have been related to technical defects of the electrode as well as ...
Silver nanoparticle-doped zirconia capillaries for enhanced bacterial filtration

Wehling, Julia; Köser, Jan; Lindner, Patrick; Lüder, Christian; Beutel, Sascha; Kroll, Stephen; Rezwan, Kurosch (London : Elsevier Ltd., 2014)

Membrane clogging and biofilm formation are the most serious problems during water filtration. Silver nanoparticle (Agnano) coatings on filtration membranes can prevent bacterial adhesion and the initiation of biofilm ...
