Post-doc Scholarship in New Types of Colorants

KTH Royal Institute of Technology

Stockholm, Sweden

KTH Royal Institute of Technology in Stockholm is the largest and oldest technical university in Sweden. No less than one-third of Sweden’s technical research and engineering education capacity at university level is provided by KTH. Education and research spans from natural sciences to all branches of engineering and includes Architecture, Industrial Management and Urban Planning. There are a total of 12,400 full year students at first and second levels, almost 1,900 active (at least 50 per cent) research students and 5,100 employees.

The workplace

Your postdoctoral studies will take place at the Department of Fibre and Polymer Technology, in the group of Polymeric Materials and in collaboration with the group of Dr. Magnus Jonsson at the Laboratory of Organic Electronics at Linköping University.

Project description

Colorants (dyes and pigments) are used to enhance the attractiveness of a number of different products such as plastics, textiles, packaging, inks, food, paints, cosmetics and pharmaceuticals. Pigments and dyes absorb certain wavelengths of light and the color of the pigment or dye is the non-adsorbed wavelengths of the light that are reflected or transmitted. The vast number of colorants includes natural pigments, bio-derived dyes as well as synthetic pigments and dyes. Unfortunately there are many synthetic colorants available on the markets that are not safe to humans and/or animals, and thus there is a need for more environmentally benign colorants.
Nature is rich in examples of structural colors. A structural color is obtained by making a periodic structure that reflects or scatters light so that the light waves of certain wavelengths can constructively interfere. The aim of the present project is to prepare a new type of particles with structural colors that are non-toxic and environmentally benign and that can be utilized as colorants of e.g. packaging, plastics and cosmetics.


The applicant should have a PhD degree obtained within the last five years (time for e.g. parental leave will be deducted), in a subject relevant to the research project, such as chemistry, physics, nanotechnology or similar. Candidates without a PhD degree, but expected to defend prior to the starting date are also welcome to apply.

Applicants should have a background in micro- and nanocapsule/particle synthesis. Candidates with expertise in microfluidics will be prioritized. Knowledge in different characterization techniques of capsules/particles (DLS, SEM, TEM, FTIR, NMR) is required.

Candidates should have good knowledge in English and a good ability to express themselves in both speech and writing. The applicant must show documented ability to publish in peer-reviewed international journals. She or He must be highly motivated, be able to work independently or together with other members in the group. Project management and good communications skills are required.
