General
Q-Sense D300 is the system of choice to get detailed information about complex surface
chemistry or biology. When you need to know how molecules adsorb to a chosen
surface or need to examine the difference between two very similar approaches for a
polymer-based biomaterial, the QCM-D technique provides crucial information about
mass and structural changes taking place at the surface.
For all applications, the instruments can:
track events in real time; be used with a large selection of substrate materials; provide information about structural changes; measure changes in mass; operate with non-labelled molecules.
QCM-D instruments from Q-Sense are already being used in a broad range of research and the technique’s potential covers most surface science applications. Here are just a few examples.
| BIOFOULING | Protein and bacterial films on stainless steel and other materials. |
| BIOMATERIALS | Identifying cell, protein and peptide adsorption/immobilisation kinetics to control the properties of biomaterial interfaces. |
|
BIO-RECOGNITION |
Investigating the interactions of molecules such as those involved in DNA hybridisation. |
| DRUG DEVELOPMENT | Looking at aspects of drug delivery such as the way in which polymer films dissolve. |
| ELECTROCHEMISTRY | Studying complex surface reactions in depth with QCM-D during electrochemical measurements. |
| FUNCTIONALISED SURFACES | Examining the properties of functionalised molecular layers, e.g. design of inert layers with active sites. |
| MATERIAL PROPERTIES | Evaluating the effect of cleaning and etching agents such as, for example, the enzymatic degradation of lipid films. |
| THIN FILM CHARACTERISATION | Examples include the study of phase transitions in liquid crystals or water absorption in polymer films. |
