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 ...
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 ...
Low-frequency magnetic response of gold nanoparticles

Harke, Saba; Habibpourmoghadam, Atefeh; Evlyukhin, Andrey B.; Calà Lesina, Antonio; Chichkov, Boris N. ([London] : Macmillan Publishers Limited, part of Springer Nature, 2023)

Gold nanoparticles (AuNPs) exposed to low frequency magnetic fields have shown promise in enhancing biological processes, such as cellular reprogramming. Despite the experimental evidence, a comprehensive understanding of ...
A remarkable discovery of electrum on the island of Sylt, northern Germany, and its Scandinavian origin

Schlüter, Jochen; Schuth, Stephan; Fonseca, Raúl O. C.; Wendt, Daniel (Göttingen : Copernicus Publications, 2021)

An electrum-quartz pebble with a weight of 10.4μg was discovered in a cliff of Saalian glaciogenic sediments on the west coast of the German North Sea island of Sylt in 2012. It has a roundish water-worn appearance and ...
Spectroelectrochemical Investigation of the Charge Carrier Kinetics of Gold-Decorated Cadmium Chalcogenide Nanorods

Miethe, Jan F.; Lübkemann, Franziska; Poppe, Jan; Steinbach, Frank; Dorfs, Dirk; Bigall, Nadja C. (Weinheim : Wiley-VCH, 2017-10-16)

The interfacial transfer of charge carriers across the semiconductor nanoparticle/electrolyte boundary is an elementary process for applications such as photoelectrochemical sensing and photocatalysis. This mechanism is ...
UV-fs-LA-ICP-MS analysis of CO2-Rich fluid inclusions in a frozen state: Example from the dahu au-mo deposit, xiaoqinling region, central China

Jian, Wei; Albrecht, Moritz; Lehmann, Bernd; Mao, Jingwen; Horn, Ingo; Li, Yanhe; Ye, Huishou; Li, Zongyan; Fang, Guanguan; Xue, Yongsheng (London : Hindawi Limited, 2018)

recently developed technique of ultraviolet femtosecond laser ablation inductively coupled plasmamass spectrometry (UV-fs-LA-ICP-MS) combined with a freezing cell is expected to improve the analysis of CO2-rich fluid ...
