What you can do

Pre-deposition Langmuir-Blodgett layer quality check

  • Monolayer/film homogeneity. When combined with a KSV NIMA L&LB Trough, observation can be performed during compression/expansion at known surface pressures. Verifying the homogeneity of the monolayer already prior to deposition will speed up the research considerably.
  • Optimizing the deposition parameters. For a high quality LB coating, the measurement parameters such as compression speed, waiting times, temperature and subphase content need to be optimized. With MicroBAM it is easy to study the effects of these parameters and choose the optimal conditions.

Langmuir layer structure and behavior studies

  • Monolayer/film behavior. It is possible to observe phase changes, phase separation, domain size, shape and packing.
  • Monitoring of surface reactions. For example, photochemical reactions, polymerization reactions as well as enzyme kinetics can be followed in real-time.
  • Monitoring and detection of surface active materials. For example protein adsorption and nanoparticle flotation.

3 reasons to invest

Camera to capture monolayers

The MicroBAM camera features a good resolution (12 µm) combined with a large field of view, which is preferred for film homogeneity and domain size studies. You are able to capture still images of monolayers manually or automatically as a function of time or surface pressure. 

Quick quality check

Before depositing your monolayer make sure it is exactly the way you want it. The MicroBAM is an optimal tool for routine LB film homogeneity check prior to deposition.

Compatible with most L&LB troughs

Compatible with most of our L&LB troughs, this easy-to-use instrument connects directly to the computer via USB starting you off in minutes.

Product in detail

The KSV NIMA MicroBAM is an easy-to-use instrument for non-invasive imaging of mono-molecular layers at the air-water interface.

By detecting changes in the refractive index of the water surface in the presence of surfactant molecules, MicroBAM provides information on homogeneity, phase behavior and film morphology without the need for any external agents such as fluorescent dyes which could interfere with the Langmuir layer. 

The good image quality and lateral resolution make it an ideal instrument for the visualization of morphological film parameters (e.g. compressed film homogeneity, domain size, shape and packing). Real-time observation and recording of film structure enables dynamic activity to be captured.

The KSV NIMA MicroBAM can be used with most KSV NIMA Langmuir and Langmuir-Blodgett Troughs, to provide real-time image measurements as a function of time or surface pressure. The KSV NIMA MicroBAM connects directly to the computer via USB making it remarkably easy to setup and use.
