一種以原子力顯微鏡為定量檢測之藥物篩選方法,係將欲結合之蛋白質固定在原子力顯微鏡之探針上,藉以量測與晶片上所固定之蛋白質間相互鍵結之結合力。其可運用到任何與疾病有關之細胞膜接受器固定於晶片上,以原子力顯微鏡量測之定量差異來篩選相關之藥物,同時藉由外加電場以改變蛋白質固定在晶片上之均一性方向,進而改變蛋白質晶片之使用效率。不僅可以多次量測且只要蛋白質之活性不消失,其實驗係可在同晶片上重複使用;若搭配微陣列技術,將多種藥物加在不同之區域,即可在同一晶片上,穫得量測多種藥物之效果,不僅快速且成本低,係一項具有潛力之蛋白質晶片分析及應用技術,可製造出更有效率之蛋白質晶片,並於降低成本同時亦能提升其品質。 A method for drug screening is provided. An atomic force microscopy (AFM) is used to obtain quantitative difference. At least one receptor is immobilized on a probe of the AFM and at least one ligand is immobilized on chips. By flowing a candidate drug on the chips or even applying different candidate drugs to different areas of each chip, drug screening is processed through measuring the binding force between the receptor and the ligand. Multiple drugs can be screened without weakening activity of the proteins during repeated drug screening processes. The drug screening process is cost saved and has high quality. Highly effective protein chips can be developed based on the present disclosure.
