Shear acoustic wave biosensor for detecting DNA intrinsic viscosity and conformation: a study with QCM-D.


Direct biosensors are devices operating by monitoring the amount of surface-bound analyte. In this work a new approach is presented where a label-free acoustic biosensor, based on a QCM-D device, and solution viscosity theory, are used to study DNA intrinsic viscosity. The latter is quantitatively related to the DNA conformation and specifically the… (More)
