Real-time resonant frequency changes ΔF (Hz) after repeated injections of MIP-PQ, MIP-SV, and NIP dispersions of increasing concentration on functionalized QCM-D sensor chips modified with (A) PQ, (B) SV, (C) hCG, and (D) LH. Figures (A) and (B) also show the frequency changes upon injecting nanogels dispersions pre-incubated with 0.1 mg·mL-1 peptide solutions (MIP-PQ + PQ and MIP-SV + SV, respectively).
