We have studied the formation of histone Hv1–DNA complexes using an acoustic biosensor and AFM imaging. Our results show that DNA and histone molecules aggregate into amorphous accumulations which form a compact rigid layer on the sensor’s surface. By measuring changes in the acoustic wave amplitude, it was possible to titrate surface bound DNA with Hv1 and discriminate between DNA molecules of different...
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 molecule's shape and size, in a manner that is independent...
