Molecular Materials (Molmat)

Molecular Materials (Molmat) is a multidisciplinary research group consisting of physicists, chemists and biologists aiming at functional materials based on supramolecular and supracolloidal self-assembly and its hierarchies.
Molmat_sample

We use polymers, conjugated polymers, polypeptides, liquid crystals, nanocellulose, metal nanoparticles, dendrimers, virus particles, carbon nanotubes and other carbon-based materials as structural and functional units in supramolecular assemblies.  Recently, we have been engaged in bio-mimetic self-assembly with a special emphasis on nacre and silk mimetics.

HYBER

The Molmat group is a part of HYBER, the Academy of Finland´s Centre of Excellence in Molecular Engineering of Biosynthetic Hybrid Materials research (2014-2019), led by Professor Ikkala. HYBER aims to use biological concepts for next generation materials science.

Nanomicroscopy Centre (NMC)

Molmat is also a part of the Nanomicroscopy Center administered by Professor Janne Ruokolainen. NMC is a cutting-edge microscopy facility offering us a number of high-resolution imaging and fabrication tools for soft, hard and biomaterial characterization.

Group leader

Professor Olli Ikkala 

I head the Molecular Materials laboratory at the Department of Applied Physics of Aalto University in Greater Helsinki and the Centre of Excellence in Molecular Engineering of Biosynthetic Hybrid Materials Research (HYBER) of the Academy of Finland. My research interest is to develop functional materials based on hierarchical self-assemblies, biomimetics, and materials originating from nature, such as nanocellulose. The laboratory is multidisciplinary, combining physics, chemistry, and materials science. I have published nearly 300 articles, including several articles in the Science and Nature family, as well as ca 20 patents, and have been cited nearly 15,000 times (H-index 66). I have twice been awarded an ERC Advanced Grant and twice an Academy Professorship of the Academy of Finland. I am an elected member of the Finnish Academy of Science and Letters and the Technology Academy of Finland.

Molecular Materials Facilities

The Molecular Materials research group is located in Nanotalo. The building also houses the Nanomicroscopy Center (NMC).

All equipment is available for external users.  Contact details of the responsible persons are listed below (Note: Each facility has a different contact person).
