Photoswitches – graphene functionalization using chiral organic molecules

In the current project, we are particularly interested in the covalent attachment of small organic molecules to 2D materials[i] and the linking of the latter via the former. While in most of our projects, the organic molecules used for surface modification are commercially available or readily available from such, some projects require more extensive synthetic efforts.…

Imaging surface of immune cells with nanoscopic precision 

Surface of immune cells commands organisation of their signalling molecules. A proper molecular organisation of these molecules determines effectivity of immune response to pathogens and cancer cells. Advanced imaging techniques such as superresolution microscopy, are required to characterise organisation of molecules with nanoscopic precision. However, sample preparation is not yet well established these methods. The…

Detection of pathogens or antibodies against pathogens using the series of LSPR active nanocomposites

The main aim of this study is to develop a new detection system for selected bacteria and viruses, as well as their proteins and antibodies against them. The detection system is focused on the localized surface plasmon resonance (LSPR) where pathogen/protein/antibody attached to the LSPR sensors (containing metal nanoparticles) changes the optical and electrical characteristics.…

Příprava a optimalizace anorganických krystalů pro detekci ionizujícího záření

Student se v průběhu stáže seznámí s charakterizací a přípravou krystalů pro scintilační detektory ionizujícího záření. Krystaly budou připravovány moderní metodou micro-pulling-down, která je v ČR instalována zatím pouze na Fyzikálním ústavu AV ČR. Bude studován vliv složení (stechiometrie) krystalů na bázi gadolinito-galito-hlinitých granátů Gd3(Al,Ga)5O12 (GAGG) a lutecito-hlinitých granátů Lu3Al5O12 (LuAG) na jejich luminiscenční a scintilačních vlastnosti. Oba…
