In this chapter we describe recent advances in the use of quartz crystal microbalance frequency shift and quartz crystal admittance/impedance analysis of self-assembled protein films complemented by ellipsometric thickness, and comparison of acoustic and optical mass/thickness. These protein films can be regarded as model systems among other applications of electrochemical biosensors based on molecular recognition and electrical signal generation through electrocatalysis of “wired “ (electrically connected) enzyme electrodes
