Using Complementary Acoustic and Optical Techniques for Quantitative Monitoring of Biomolecular Adsorption at Interfaces

Abstract The great wealth of different surface sensitive techniques used in biosensing, most of which claim to measure adsorbed mass, can at first glance look unnecessary. However, with each technique relying on a different transducer principle there is something to be gained from a comparison. In this tutorial review, different optical and acoustic evanescent techniques […]

A comparative study of protein adsorption on titanium oxide surfaces using in situ ellipsometry, optical waveguide lightmode spectroscopy, and quartz crystal microbalance / dissipation

Abstract The adsorption kinetics of three model proteins—human serum albumin, fibrinogen and hemoglobin—has been measured and compared using three different experimental techniques: optical waveguide lightmode spectroscopy (OWLS), ellipsometry (ELM) and quartz crystal microbalance (QCM-D). The studies were complemented by also monitoring the corresponding antibody interactions with the pre-adsorbed protein layer. All measurements were performed with […]

QCM-I QCM-D Quartz Crystal Microbalance Device By MicroVacuum Ltd

QCM-I (QCM-D)

QCM-I Quartz Crystal Microbalanace With Impedance Measurement: The QCM-I measuring unit is a high-sensitivity mass sensor, which measures the change in frequency of a quartz crystal resonator and as a label free biosensor it measures the “wet mass” of the adsorbed layer in processes occurring at or near the sensor surface.
