Survey on photoluminescent Gold Quantum Clusters - for scientists working with fluorescence-based techniques

Dear fellow scientists!

I am a hungarian PhD student working in the field of nanochemistry. I develop photoluminescent gold quantum clusters (GQCs) for biological application. GQCs are novel material systems with visible emission. They can substitute organic fluorophores and semiconductor quantum dots in imaging techniques.…

Electronic properties probed by scanning tunneling spectroscopy: From isolated gold nanocrystal to well-defined supracrystals

Scanning tunneling microscopy and spectroscopy at 5 K have been used to determine the electronic properties of 7-nm dodecanethiol-passivated Au nanocrystals in three different configurations: isolated nanocrystal, self-organized thin films (few nanocrystal layers), and large three-dimensional well-defined thick films (over 30 nanocrystal layers) called supracrystals. The electronic properties of both thin and thick well-ordered supracrystals are analyzed in scanning tunneling spectroscopy…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at

Dr. András Paszternák, founder of Nanopaprika
