Stella Vallejos^1,2, Naděžda Pizúrová³, Jan Čechal⁴, Isabel Gràcia¹, Carles Cané¹

¹Instituto de Microelectrónica de Barcelona (IMB-CNM, CSIC), ²SIX Research Centre, Brno University of Technology, ³Institute of Physics of Material, Academy of Science of Czech Republic, ⁴Institute of Physical Engineering and Central European Institute of Technology, Brno University of Technology

Columnar zinc oxide structures in the form of rods are synthesized via aerosol-assisted chemical vapor deposition without the use of pre-deposited catalyst-seed particles. This method is scalable and compatible with various substrates based on either silicon, quartz or polymers.

¹Department of Chemistry and Biochemistry, Mendel University in Brno, ²Central European Institute of Technology, Brno University of Technology

This protocol describes the synthesis of magnetic particles and evaluation of their DNA-binding properties via dynamic and electrophoretic light scattering. This method focuses on monitoring changes in particle size, their polydispersity and zeta potential of particle surface which play major role in binding of materials such as DNA.

A graphical user interface for exploring and sharing a database of optogenetically-induced vascular responses in mouse somatosensory cortex in vivo measured by 2-photon microscopy is presented. It allows browsing the data, criteria-based selection, averaging, localization of measurements within a 3D volume of vasculature and exporting the data.
