Information about the Research Project
Nanotechnology promises smart solutions for the future in many areas. However, manufactured and unintentionally produced nanoparticles are released into nature with unknown environmental consequences. To this end, it is known that nanoparticle dimension, composition and shape may play a critical role in determining their toxicity and fate. Furthermore, there is a knowledge gap about transformations of nanoparticles upon environmental entry and how these transformations affect the acute toxicity and long- term sub-lethal effects at low nanoparticle concentrations.
A so-far unexplored concept in the field of environmental nanosafety is to study the interaction of individual nanoparticles with the environment. The main motivation for the development of methodologies that enable studies of single nanoparticles is that they entirely eliminate ensemble-averaging artifacts, which may hinder understanding of particle structure - toxicity correlations down to the atomic level. Therefore, the focus of this postdoc position is the application of our experimental method "single particle plasmonic nanospectroscopy" to investigate the interaction of single metal nanoparticles with natural organic matter, in an effort to understand how atomistic details of nanoparticle structure deterimine their toxicity. The project is part of a large Swedish research consortium entitled "Mistra Environmental Nanosafety", coordinated by Prof. Tommy Cedervall at Lund University.

Information about the research group
The Langhammer group at the Chemical Physics Divison at the Department of Physics operates at the interface between materials science, nanoscience, catalysis, nanoplasmonics and in situ spectroscopy, with a particular focus on sustainable energy-related materials, nanosensors, nanoparticles and more recently also environmental nanosafety. For that purpose we continuously develop and evolve our own methodologies for state-of-the-art nanofabrication, as well as build our own customized research instrumentation. Now we intensify our efforts towards employing single particle techniques for the investigation of interactions between natural organic matter and nanoparticles in an environmental nanosafety context.
For more info, please visit the group home page: www.langhammerlab.se; and the home page of the Chemical Physics Division that hosts the Langhammer Group:
• design experiments and samples for the study of natural organic matter interaction with single metal nanoparticles with tailored size, shape and structure.
• learn and implement the use of single particle plasmonic nanospectroscopy for environmental nanosafety applications.
• study the interaction of natural organic matter with individual nanoparticles with respect to the impact of particle size and shape, as well as microstructure.
• evaluate and summarize your data and share them with our cross-diciplinary research team, as well as with the researchers within the Mistra Environmental Nanosafety consortium on a regular basis.
Your major responsibility as postdoc is to perform your own research in a research group. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.
Full-time temporary employment. The position is 1+1 year postdoc position.
To qualify for the position of postdoc, you must have a doctoral degree in Physics, Applied Physics, Nanotechnology, Chemistry or the Life Sciences/Biology. The degree should generally not be older than three years.
Mandatory experiences and skills:
You must have hands-on experience with experimental work involving nanoparticles in at least one of the following contexts:
(i) nanoparticle synthesis/nanofabrication;
(ii) nanoplasmonic sensing and spectroscopy;
(iii) environmental nanosafety.
Meritorious experiences and skills:
- Excellent collaboration skills.
- Experience with single particle experimental methods.
- Experience with experimental assessment of nanoparticle-biomolecule interactions.
- Experience with analysis of complex scientific data.
- Experience with computer programming using Python or MATLAB.
- Experience with working in a highly cross-disciplinary project at the interface between physics, chemistry and biology.
The position also requires excellent communication skills in written and spoken English. Applicants who do not have English or a Scandinavian language as their mother tongue need to provide documentation of good communication skills in English, typically evidenced by an English language test, for example TOEFL 550 (paper-based)/TOEFL 213 (computer-based), and exemplified during the interview process prior to admission. Chalmers offers Swedish courses.
Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
