Nanocrystals multicolor nanopatterns for advanced biosensing
Master
Cover

Short Description:
Semiconductor nanocrystals (NCs) exhibit fluorescent that is a powerful tool for sensing. The fluorescent properties of NCs originate from quantum confinement that occurs when the size scale of the material becomes less than or equal to the characteristic length of the probing property, here the distance between electron-hole pair or exciton Bohr radius. The fluorescent of NCs results from recombining an electron-hole pair in which the photoexcited electron in the conduction band recombines with the hole left behind in the valance band. The energy of the emitted photon, i.e., wavelength or emitting color, depends on the NC band-gap that is determined by the size and the shape of the material. Multicolor patterning of NCs, fabrication of highly ordered multicolor patterns from NCs with different sizes/shapes, is an essential step in producing novel sensing platforms. In this project, the main task is to address the challenges of producing distinct NC patterns using the electron beam lithography technique.

Tasks:
1- Carry out literature research on nanopatterning of semiconductor nanocrystals
2- Establish an experimental plan for the fabrication of the PMMA template and optimize the nanopatterning parameters
3- Pattern-assisted stacking of red- and green-emitting semiconductor nanocrystals

Requirements:
We are looking for a top-level student in Materials Science or Natural Science with excellent verbal and written communication skills in English who wants to make a mark in science. Knowledge of working with colloidal semiconductor nanocrystals is an advantage. The candidate must be able to work independently and progress in the research work by own achievements. He/she must be creative in solving experimental challenges. A fundamental part of the work will be reporting the results. The candidate must be experienced in writing technical/scientific reports. It is expected that the candidate has a solid research-ethical approach. The primary workplace will be the Institute of Materials Science and Nanotechnology and Max Bergmann Center of Biomaterials Dresden.
Our group does not discriminate based on race, color, gender identity, religion, or national origin. The application from students with disabilities will be particularly welcome.

Benefits:
We offer exciting tasks in a robust international academic environment as well as an open and inclusive work environment with dedicated colleagues. The student will learn advanced nanofabrication techniques and experience multidisciplinary nanomaterial research and development.
