Cetuximab is a monoclonal antibody that binds to the epidermal growth factor receptor, which is important in the growth of many cancers. However, the biophysical characteristics of cetuximab as an anti-cancer drug remain elusive. In this study, we adopted atomic force microscopy to measure the mechanical properties of cancer cells following cetuximab treatment and the biomechanical properties of cetuximab and epidermal growth factor receptor interactions. Atomic force microscopy can be implemented as a platform for further investigations that target the cellular stiffness and affinity of ligand-receptor as a therapeutic choice.
西妥昔单抗是一种单克隆抗体，可与表皮生长因子受体结合，而表皮生长因子受体在许多癌症的生长过程中起着重要作用。然而，西妥昔单抗作为一种抗癌药物的生物物理特性仍然难以捉摸。在本研究中，我们采用原子力显微镜来测量西妥昔单抗治疗后癌细胞的力学性质以及西妥昔单抗与表皮生长因子受体相互作用的生物力学性质。原子力显微镜可作为一个平台用于进一步研究，这些研究以细胞硬度和配体 - 受体亲和力作为治疗选择为目标。
