PhD student in Paper-based Diagnostics

Department of Chemistry, with more than 200 employees, is one of the largest departments at Stockholm University. The Research spans all areas of chemistry such as analytical chemistry, physical chemistry, materials chemistry, inorganic and structural chemistry and organic chemistry. The research projects are many from theory to experiment, from basic research to more applied projects often focusing on sustainable chemistry but also advanced analytical methods of chemicals and materials. The department has a very well-developed research infrastructure with state-of-the-art equipment with qualified support from staff scientists.

The department also hosts the Bachelor's degree programme in chemistry and three Master's programmes: analytical chemistry, sustainable chemistry, and organic chemistry. PhD programmes are conducted in five areas: analytical chemistry, physical chemistry, materials chemistry, inorganic chemistry and organic chemistry.

Subject area 

The PhD student will work in the Research Group of Associate Professor Georgios A. Sotiriou (https://sotirioulab.org) located at the Department of Chemistry and Science for Life Laboratory (SciLifeLab). The co-supervisor is Professor Nicole Pamme from the same Department at Stockholm University.

Project title: Paper-based diagnostics with optically active nanoparticles.

Project description: Paper-based diagnostics exhibit great potential for environmental and health sciences applications. In this project, the doctoral candidate will directly deposit optically active nanoparticles on filter papers by flame aerosol direct deposition and utilize them for point-of-care diagnostics in biomedicine (e.g. to detect bacterial presence in biological fluids), and for environmental applications, for example to detect the presence of pesticides in agricultural products. The project includes:

• Production of nanoparticles by flame aerosol synthesis.
• Physicochemical characterization of nanoparticles.
• Deposition of nanoparticles on paper substrates and their characterization.
• Establishing structure-function relations to understand the sensing capabilities of optically active nanoparticles.
• Assess their performance in detecting bacterial presence and/or toxic substances.

Qualification requirements

In order to be admitted to postgraduate education, the applicant must have the general and specific entry requirements. The qualification requirements must be met by the deadline for applications.

You meet general entry requirements if you have completed a second-cycle degree, or completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

Specific entry requirements are described in the general syllabus for doctoral studies in the field of chemistry.

Selection

The selection among the eligible candidates will be based on their capacity to benefit from the training. The following criteria will be used to assess this capacity:

• documented knowledge in a relevant field of research
• capacity for analytical and creative thinking
• initiative
• independence
• ability to collaborate
• written and oral proficiency in English.

The candidate should hold a MSc in Chemical and/or Process Engineering, Nanotechnology, Engineering Physics or similar field. Experience in flame aerosol processes, nanoparticle technology and solid state characterization is desirable. Further experience with biosensors and diagnostics is considered a plus.

About the employment

We offer a fixed-term employment as a doctoral student according to Chapter 5 of the Higher Education Ordinance (1993:100). The period of employment may not be longer than what corresponds to full-time doctoral education for four years. As a doctoral student, you should primarily devote yourself to your own doctoral education, but the employment may include work with education, research and administration to a limited extent (maximum 20 %).

A new employment as a doctoral student is for a maximum of one year, the employment is then renewed for a maximum of two years at a time.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
