超高速視頻級(jí)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(duì)歷經(jīng)數(shù)十年研發(fā)而成的,也是世界上第一臺(tái)可以達(dá)到視頻級(jí)成像的商業(yè)化原子力顯微鏡。

相較于目前市場(chǎng)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(tái)可供選擇。樣品無(wú)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(dòng)態(tài)觀測(cè)。液體環(huán)境下直接檢測(cè),超快速動(dòng)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(duì)生物樣品等的損傷。懸臂探針可自動(dòng)漂移校準(zhǔn),適用于長(zhǎng)時(shí)間觀測(cè)。采用動(dòng)態(tài)PID控制,高速掃描時(shí)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(jí)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(jí)雜志。
