Welcome!
We are a new lab investigating chemical and physical properties of matter at the nanoscale. We are particularly interested in:
* New approaches to the synthesis of nanocrystals
* Self-assembly of nanoparticles
* Organic nanostructures
* Supramolecular chemistry
* Chemical reactivity in confined spaces
* Molecular switches
* Stimuli-responsive materials
Available positions:
Rotation, M.Sc. and Ph.D. positions available. Postdoc positions available for outstanding candidates.
Please inquire with Dr. Rafal Klajn.

NANOPARTICLE HELICES
Controlled assembly of nanoparticles is of paramount importance for the understanding of their fundamental properties and for the development
of new functional materials. We have recently developed a method to assemble nanocrystals into well-defined helices as thin as 100 nm and as
long as 1 mm (see SEM pictures below). Note that the pitch of the helices is on the order of the wavelength of the visible light (and can
be regulated!), making these structures attractive candidates for investigating the effect of light on various material properties.

WORLD'S SMALLEST METALLIC BOWLS?
We have developed a solution synthesis of metallic nanoparticles with a unique shape of tiny bowls. These "nanobowls" have cavities just few
nanometers across and can be used to "trap" other nanosized objects. The picture below is a collage made of several tomograms reconstructed
from data collected using scanning transmission electron microscopy. This is how the nanobowls really look like in three dimensions!
