New publication using Attana’s QCM-technology for optimization of biosensor surfaces using different flow types

Researchers at the University of Chemical Technology and Metallurgy, Bulgaria and Sofia University have with Attana’s QCM-technology investigated the effect of different process parameters when preparing functionalized biosensor surfaces. This is important for developing and optimizing new sensors for many different applications.

Polymers and biomolecules, such as proteins, are used as recognition elements for different kind of biosensors. In order to develop new or improved biosensor surfaces, it is important to understand the influence of different process parameters. In the publication “Effects of the Flow type on the immobilization of Horseradish peroxidate on polymers”, assistant professor Spaska Yaneva and co-workers have studied the effect of turbulent and laminar flow and an intermediate state with respect to immobilization properties of biosensor surfaces.  They demonstrated a flow type effect on coating amount, time, structure and moleculular orientation, and consequently the function of the surface.. Attana QCM was used to quantify the amount of immobilized enzymes at laminar flow. This work can be combined with other studies on biosensors optimization, such as effect of pH and surface charge to form a comprehensive knowledge of biosensor surfaces development.
