System for characterization of colloids by dynamic light scattering within a size range of 0.8 nm to 6.5 µm. Suitable for material systems with concentrations from ppm up to 40% vol., depending on substance type. Minimum is 1 droplet. Particle Size Distribution The NANO-flex® 180° DLS System measures size distributions in the range of 0.8 nm to 6.5 µm. The applied heterodyne 180° back scattering principle of the Nanotrac® is characterised by its high selectivity in the nano-range and is therefore also suitable for samples with broad size distribution. Highly concentrated samples are measured without interfering multiple scattering. The applied Nanotrac® back scattering in the NANO-flex® is designed as a flexible measuring probe with 8 mm ø. Thus, it can be used in many ways, even in-situ and in the measuring cylinder of the Stabino®! Molecular weight determination according to Debye Further to the DLS size, a Debye plot feature with automatic dn/dc determination provides molecular weight.

Lateral force microscopy on polystyrene-polybutadiene blend
The lateral force imaging mode was used to image local friction differences between the two polymersPolystyrene and polybutadiene are shown to have quite different surface properties
This report demonstrates the capability of the FlexAFM in studies of charged solid-liquid interfacesIn order to carry out electrochemical(in-situ)AFM experiments, a conductive sample was mounted in an electrochemical liquid cell and connected to a lab-build bipotentiostat. We employed Clavilier-type Au(111) single crystal bead crystal electrodes with facets of micrometer-wide terraces. As examples, we studied the lifting of the Au(111)-(pxV3)reconstruction, surface oxidation as well as the growth and dissolution of copper clusters in sulfuric acid solution.

KPFM using the Nanosurf FlexAFM
Kelvin probe force microscopy imagingKelvin Probe Force Microscopy (KPFM) is an extension of AFM. The technique was first published in 1991 by Nonnenmacher and coworkers. Using KPFM, images can be recorded that contain information on the local work function or local contact potential difference between tip and sample. Although all Nanite systems with an SPM S200 controller and all current Easyscan 2 AFM systems are in principle capable of performing KPFM, the FlexAFM has demonstrated best KPFM performance and is therefore the instrument of choice for this type of measurement.

Performance without compromise
The DriveAFM, Nanosurf‘s new flagship instrument, utilizes the latest technology to deliver stable, high-end performance. It was designed to fulfill the needs of top notch research, today and in the future.
- CleanDrive: stable excitation in air and liquid
- Ultra-low noise
- Direct drive: high-resolution imaging and large scan area
- Fully motorized system: full control via software
CleanDrive: stability in air and liquid with photothermal excitationPhotothermal excitation of the cantilever provides unparalleled stability, a linear frequency response, and a high excitation bandwidth in air and liquid environments. These benefits allow measurements at multiple frequencies and highspeed applications and open new horizons for innovative new measurement modes (e.g. Cytomass Monitor). These advantages are amplified in liquids since only the cantilever beam is excited and the liquid environment remains largely unperturbed. This results in clean resonance peaks and not the “forest of peaks” commonly seen with the piezo acoustic excitation of cantilevers. Furthermore, this method of exciting the cantilever is insensitive to changes in the environment and distance to the sample, making the whole measurement system much more stable. The DriveAFM, with its small light spots, is compatible with the use of small cantilevers, which have several advantages that make them superior in performance. While they have the same spring constant as a conventional cantilever, small cantilevers show a significantly higher resonance frequency and operational bandwidth. Also, the noise performance is better. Due to the small dimensions, the sensitivity is increased, and hydrodynamic drag is decreased. All of this results in better imaging performance.
Ultra-low noiseThe DriveAFM has a very low overall noise floor, which is achieved through a combination of a low-noise/low-coherence superluminescent diode and a low-noise/high-bandwidth photodetector used in the beam deflection detection module and the low-noise/high-bandwidth CX Controller. This is the basis for the stable, sensitive, and high-resolution imaging and force spectroscopy capability of the DriveAFM.
Direct drive scanner
The DriveAFM exploits the power of direct drive piezo actuation. The 1:1, non-geared actuation scheme of the DriveAFM’s flexure scanner provides more force and can drive stiffer scanners. The resulting higher resonance frequency of the scanner components allows for a higher available actuation bandwidth than with geared drives of the same scan size. The direct drive scanner actuation in combination with the low noise 28-bit CX Controller allows for both imaging at large scales and at high resolution. The DriveAFM is the perfect solution for high-resolution imaging of demanding samples such as nanostructures, proteins, or polymeric structures (e.g. DNA), and also for larger, micrometer-sized structures.
