In situ AFM Measurements of Ionic Liquid Gating

The in situ AFM measurements were carried out in a Cypher (Asylum Research)
atomic force microscope. An integrated blueDrive (Asylum Research)
laser was used to actuate the oscillation of the cantilever (AC-55
TS, Olympus) in the IL. During AFM scanning, the cantilever, gate
electrode plate (Au), and SCO sample were all covered by the IL (Figure 1a), and the gate
voltage was applied by an external source meter (Keithley 2400). The
ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide
(EMIM-TFSI), was used for all IL gating experiments. The IL and the
devices were separately baked at 380 K in high vacuum (10^–7 mbar) for at least 12 h before the gating experiments were carried
out. Except for the H₂O-vol % dependent XPS measurements,
dried IL was otherwise used for all measurements.

Atomic Force Microscopy of Titin Molecules

Check if the same lab product or an alternative is used in the 5 most similar protocols

Titin samples were imaged with a high-resolution atomic force microscope (Cypher, AsylumResearch, Santa Barbara, CA). Dehydrated samples were imaged in tapping mode with a stiff cantilever (Olympus AC160 or AC55TS with nominal tip radii of 9 and 7 nm, respectively) at a line-scan rate of 3–6 Hz and pixel resolution of 0.5 - 2 nm. Hydrated samples were scanned in tapping mode with a soft, high-resonance-frequency cantilever (Olympus BL-RC150VB, BioLever B, nominal tip radius 25 nm) a a line-scan rate of 2–3 Hz and a pixel resolution of 2–4 nm. Images were corrected for flatness of field and color contrast (offset and range) by using built-in algorithms of the AFM driver software. Topographical distance (e.g., filament width) measurements were corrected for tip convolution as published earlier [29] (link). Accordingly, titin molecule width (W) was calculated as where W_m is measured width at half of the maximum, r is tip radius and h is topographical height in the filament axis. The width of topographical gaps (G) was obtained as where G_m is the measured gap width.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
