Polydopamine can form black nanoparticles and has recently been gaining attention due to its extraordinary heating properties upon excitation with light. Herein, polydopamine hybrid nanoparticles are synthesized in different sizes and subsequently added to a solar fluid to analyze heating ability. The solar fluids with the differently sized hybrid polydopamine particles are compared to a...

ZHO-1, an intrinsic MBL from the environmental Gram-negative species Zhongshania aliphaticivorans

Kieffer, Nicolas ; Guzmán-Puche, Julia ; Poirel, Laurent ; Kang, Hyo Jung ; Jeon, Che Ok ; Nordmann, Patrice

In: Journal of Antimicrobial Chemotherapy, 2019, vol. 74, no. 6, p. 1568–1571

Objectives: Our aim was to characterize the putative MBL of the environmental strain Zhongshania aliphaticivorans isolated from a marine environment.Methods: The putative MBL was identified in silico using the NCBI database. The β-lactamase gene was cloned into different Escherichia coli backgrounds. Kinetic parameters were determined using the purified enzyme.Results: The enzyme named ZHO-1...

Plasmon-assisted Förster resonance energy transfer at the single-molecule level in the moderate quenching regime

Bohlen, J. ; Cuartero-González, Á. ; Pibiri, E. ; Ruhlandt, D. ; Fernández-Domínguez, A. I. ; Tinnefeld, P. ; Acuna, Guillermo P.

In: Nanoscale, 2019, vol. 11, no. 16, p. 7674–7681

Metallic nanoparticles were shown to affect Förster energy transfer between fluorophore pairs. However, to date, the net plasmonic effect on FRET is still under dispute, with experiments showing efficiency enhancement and reduction. This controversy is due to the challenges involved in the precise positioning of FRET pairs in the near field of a metallic nanostructure, as well as in the...

Distribution of polymer-coated gold nanoparticles in a 3D lung model and indication of apoptosis after repeated exposure

Chortarea, Savvina ; Fytianos, Kleanthis ; Rodriguez-Lorenzo, Laura ; Petri-Fink, Alke ; Rothen-Rutishauser, Barbara

In: Nanomedicine, 2018, vol. 13, no. 10, p. 1169–1185

Aim: The distribution and impact of aerosol-delivered gold nanoparticles (AuNPs) functionalized with a mixture of aminated-polyvinyl alcohol and amino-PEG ([polyvinyl alcohol/PEG]-NH2) upon repeated administration onto a 3D lung model were explored. Materials & methods: AuNPs were aerosolized and uptake and epithelial translocation was assessed by inductively coupled plasma optical-emission ...
