超高速視頻級原子力顯微鏡（Sample-Scanning High-Speed Atomic Force Microscope ，HS-AFM SS-NEX）是由日本 Kanazawa 大學(xué) Prof. Ando 教授團(tuán)隊歷經(jīng)數(shù)十年研發(fā)而成的，也是世界上第一臺可以達(dá)到視頻級成像的商業(yè)化原子力顯微鏡。

相較于目前市場上的原子力顯微鏡成像設(shè)備，HS-AFM突破了 “掃描成像速慢”的限制，掃描速度最高可達(dá) 20 frame/s，并且有 4 種掃描臺可供選擇。樣品無需特殊固定染色，不影響生物分子的活性，尤其適用于生物大分子互作動態(tài)觀測。液體環(huán)境下直接檢測，超快速動態(tài)成像，分辨率為納米水平。探針小，適用于生物樣品；懸臂探針共振頻率高，彈簧系數(shù)小，避免了對生物樣品等的損傷。懸臂探針可自動漂移校準(zhǔn)，適用于長時間觀測。采用動態(tài)PID控制，高速掃描時仍可獲得清晰的圖像。XY軸分辨率2nm；Z軸分辨率0.5nm。
超高速視頻級原子力顯微鏡HS-AFM推出至今，全球已有80多位用戶，發(fā)表 SCI 文章 200 余篇，包括Science, Nature, Cell 等頂級雜志。
