April 2011, Issue 01 – Dimension Icon: A User's View

Field of Study

Dr. Rolf Seemann and his students at the Universitat des Saarlandes are exploring the properties of droplet-based microfluidics, which could be used for combinatorial applications in chemistry and biotechnology. Besides the applications, they are interested in such fundamental questions as what are the topological rearrangements, stability, friction and rupture of thin films, and how (bio) molecules can be oriented with the help of emulsion topology.

The Need

Dr. Rolf Seemann was searching for an atomic force microscope (AFM) that would accommodate soft matter sample characterization, and which could perform in situ scanning of liquid polymer structures at both high temperatures and at best possible time resolution. The polymer features have slopes as high as 75 degrees, and the right AFM would allow for a temperature change of more than twenty degrees Celsius while scanning. Furthermore, the AFM would need to quantify the elastic properties of the samples relatively quickly with good lateral resolution.

The Solution

The Dimension Icon.

"To make a long story short: we received the first Icon delivered in Europe. The first pleasant surprise was that the Icon was ready for shipment even before the scheduled date. Since the first day of installation, the Icon has worked extremely well, stably, and reliably."
-- Dr. Rolf Seemann

Dr. Seemann was looking for a new solution to address the application's special needs, and his experience led him to select a new advancement in AFM technology. The Icon is built upon the next-generation Dimension platform to advance optical quality, trackability, imaging speed, and thermal stability to the next level. Dr. Seemann says;

Dimension Icon

"The closed-loop system works very well with a very low noise level and was never turned off within more than one year of usage. The excellent heater allows for continuous scanning even when a steep temperature ramp is applied. For our time-resolved experiments, we gain almost one order of magnitude in time resolution compared to your former AFM platforms. The HarmoniX® mode allows for fast and quantitative determining of elastic properties at typical AFM resolution."

The Icon proved to be an excellent choice for Dr. Seemann. After a year of daily use, Dr. Seemann summarized his experience working with our team and the Dimension Icon:

"It was always a pleasant and trustful interaction, and their promises were never too high. The Icon gave our projects a big boost."

Bruker's goal is to provide next-generation solutions to help further your research, backed by unsurpassed customer service.
