Finding the right balance : By utilizing the Gaussian shaped oscillation–amplitude distribution across the surface of a sensor, it is demonstrated how the driving voltage of the crystal of a quartz crystal microbalance can be used to ensure binding of vesicles above a predefined radius to the peripheral regions of the crystal only, thus ensuring the presence of smaller sized vesicles in the central region of the crystal.
