Study Drug-Molecule Interactions at the Nanoscale

Part of: Drug Research

Visualization and characterization of small molecule-protein interactions.

In this example, optical tweezers are used to catch a DNA molecule tethered between two beads, while a motor protein and differently labeled small molecules are visualized by correlative fluorescence microscopy. The illustration shows how small molecules interact with the motor protein, thereby reducing or altering its activity. Alternatively, the small molecules can interact with the DNA template, resulting in barriers that restrict the movement of the proteins.

This is only one example of what can be investigated using this technology. Contact us to see how optical tweezers can benefit your research.


C-Trap® Optical Tweezers Fluorescence & Label-free Microscopy

Optical Tweezers and Fluorescence Microscopy

The C-Trap is the world’s first instrument that allows simultaneous manipulation and visualization of molecular interactions in real-time. It combines high-resolution optical tweezers, confocal microscopy or STED nanoscopy with an advanced microfluidics system in a truly integrated and correlated solution.
