News & Innovations

smartWLI compact used for basic bio-medical research (development of new vaccines and drugs)
In view of the current Covid-19 situation, new drugs and vaccines must be developed under high timely pressure. In this context, the bio-medical research of the German Max Planck Institute of Colloids and Interfaces may arouse some interest.
The Institute uses a smartWLI-compact table-top measurement instrument for the topographical vertical scanning interferometry (VSI) in order to collect 3D surface images of the bound antibodies „anti-Flag“ and „anti-HA“ to the corresponding peptides on the array.
So called „docking points" are created for bio-molecules, whose size is checked with the smartWLI compact *. The antibodies are usually around 10 nm in size.
The method used ultimately serves to accelerate the development of new drugs and vaccines.
