A strategy utilizing PEG linkers to enhance binding avidity and selectivity of hetero‐HMAs: a) A schematic illustration of the incorporation of the PEG linkers to increase interpeptide distances of HMAs. b) The retention of surface‐bound MCF‐7 and Jurkat cells on the HMAs and PEGylated HMAs upon washing at a flow rate of 50 µL min⁻¹, which corresponds to a maximum shear stress of 0.36 dyne cm⁻². c) The retention of surface‐bound MCF‐7 cells upon washing at a flow rate of 500 µL min⁻¹, which corresponds to a shear stress of 3.6 dyne cm⁻². d) AFM adhesion force measurements on HeMA versus PEGylated HeMA using a BSA‐immobilized probe. Significance levels are indicated as ^* p < 0.05, ^** p < 0.01, and ^*** p < 0.001, which are analyzed using Student's t‐test (cell retention) or the Mann–Whitney U test (AFM analysis).
