etal nanoparticles attract a lot of interest due to

their electronic and optical properties, but uniform

physical properties can only be expected if the size, shape

and composition of particles are homogeneous. Microfluidic

techniques allow to generating colloidal solutions of

differently shaped and constructed nanoparticles with very

high yield and homogeneity. The spectral properties of their

colloidal solutions allow to improving the understanding of

their physical properties and their growth and aggregation

behavior. It was found that electrical charges, electrostatic

interaction, electrochemical processes and mixed potential

formation as well as self-polarization and enhanced charging

and polarization due to attachment and mobility of poly ionic

macromolecules play key roles in nanoparticle formation. In

result, homogenous colloids of simple spheres, core/shell

particles, nanorods, Nano cubes, nanotriangles of metals as

well as spherical, ellipsoidal, Dumbell like, branched, astragal-

and flower-like polymer nanoparticles and different metal/

polymer composite particle types have been obtained. The

mechanisms of their formation and application in particle-

based SERS-sensorics and flow catalysis will be discussed.

Speaker Biography

J. Michael Köhler is the head of the Department of Physical Chemistry and Micro

Reaction Technology at the Technical University of Ilmenau (Germany) since 2001.

He studied Chemistry in Halle an der Saale and Jena, where he also habilitated in

General and Physical Chemistry (1992). He led a research department at the Institute

of High Technologies in Jena between 1991 and 2001. During this time, he also taught

at the Universities of Wuppertal and Jena. Professor Koehler inter alias has edited

books on microlithography, micro system technology and nanotechnology. His current

research interests are focussed on nanotechnology, on application of droplet-based

microfluidics in nanoparticle syntheses and bio screenings and on physicochemical

aspects of sustainable chemistry.

Microfluidic synthesis supply new insights into properties and behavior of metal and composite

nanoparticles
