301R_IX71 顯微鏡簡介                                                                      2011/06/13 版本

各項功能說明:

1. 暗視野顯微鏡(Dark Field Microscopy)

功能:可增強物體之影像對比,樣品需為可見光能(部分)穿透之樣品,主要為觀測物體之散射光。

光源:鹵素燈

解析能力:空氣聚光鏡式50nm,

應用:奈米金屬顆粒或活體、未經染色的生物樣品。

2. 內全反射式螢光顯微鏡(Total internal reflection fluorescence microscope, TIRFM)

功能:利用光學漸逝波(evanescent wave)激發物品之螢光,可觀測距離蓋玻片表面300nm(主要為100nm)內之螢光訊號,能達到高SNR的影像

光源:488nm、532nm、638nm 雷射光源

解析能力:單顆蛋白質修飾螢光或單顆量子點(Quantum ot)可辨析 (但間距需>500 nm)

應用:細胞貼附(adhesion)偵測、螢光修飾之單分子觀測

3. 顯微鏡式可見光波段光譜儀(Spectrometer)

功能:分析400-700nm 波段之光譜、EM CCD 拍照

光源:穿透式氦氣燈、反射式汞燈、488nm、532nm、638nm 雷射光源

光譜解析能力:0.1 nm wavelength

應用:螢光波段光譜分析

4. 共軛焦顯微鏡(Confocal Scanning Microscope)

功能:利用PZT移動Z軸做切片掃描試片,可建立3-D螢光影像,可提高螢光SNR(觀測物體範圍較TIRF 大、光訊號較弱)

Z 軸空間解析度:約300nm (100X 油鏡)

拍照能力及限制:約1-10 張/秒 ,視樣本狀況與掃描區域決定(若螢光強則速度快,反之則慢)。

光源:488nm、532nm、638nm 雷射光源for 高效率共軛焦切片,其他光源效果較差

應用:細胞螢光3-D分佈觀測

PS.以上每項功能基本訓練3 次(至少含兩次自行操作),並協助更新使用手冊後,方可申請考核,考核皆由Super User進行,如需考核,請自行與super user聯繫約定考核時間。

申請訓練注意事項 :

1. 所需功能可單項申請,請先向學長姐或老師確認是否需求,再諮詢superuser細節,再填申請表決定所需功能,即可申請訓練。

2. 申請期限:每年統一於寒、暑假期間固定訓練與考核,每周僅提供兩時段,每時段上限兩人,訓練時間由管理者視該年度情況而定。報名請至新館703R 洽詢填表或逕行寄e-mail於管理者(見下面Super User List)。其餘時間(除寒暑假外),僅提供自行操作訓練或考核,並請與合格使用者約陪同練習時間。

3. 每位合格使用者有義務認養至少一位需陪同練習訓練的訓練者,無故不願陪同訓練者,將予以停權。

4. 一般使用者開放時段: 周一至周五10:00~22:00。若有特殊需求請洽儀器管理者,待評估後可開放延長使用時間。一般使用者一周內可預約時段為6 小時,每training 其他使用者一次,可增加預約時段1 小時,當累積時數至12 小時,且經管理者評估其使用能力後可晉升為Super User。Super User 於一般使用者開放時段內,可預約上限為12 小時,非一般使用者開放時段則不受限。
