In this regard, the quartz crystal microbalance with dissipation monitoring (QCM-D) has proven to be a powerful technique to follow in situ the binding of S

The SLB membranes represent a simplified model system of the living cells membranes, which makes the successful observation of SERS on these films promising in view
