• microbalance with dissipation monitoring (QCM-D) reveals that reducing D below RPEG (D < RPEG) forces chain extension through lateral compression, forming brush conformations where the excluded volume effect dominates [14]. For PEG2k (RPEG2k ≈ 8.2 nm), achieving this brush regime requires interchain distances

• Flory radius (RPEG) of PEG and the interchain distance (D). According to polymer scaling theory, when D exceeds twice RF (D > 2RPEG), chains exist as isolated mushrooms with minimal overlap, enabling protein penetration to the nanoparticle surface. Experimental validation using quartz crystal

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
