Label-free detection of the aptamer binding on protein patterns using Kelvin probe force microscopy (KPFM)
The KPFM characterization of lysozyme patterns.
Subsurface characterization of carbon nanotubes in polymer composites via quantitative electric force microscopy
Enhanced EFM subsurface imaging of 0.5% SWCNT (LA)–polyimide nanocomposite film using an HAR probe. EFM bias voltage and lift height is 12 V and 50 nm, respectively. (a) SEM image of a conventional probe, (b) SEM image of an HAR probe. Inset: enlarged image of circled area near tip apex. (c) and (d) EFM phase image of subsurface CNTs using a conventional and HAR probe, respectively. (e) and (f) Cross-section analysis of segmented line at (c) and (d), respectively. EFM phase scale 20◦. The EFM phase signal at circled peak in (f) is both stronger and sharper than that in (e).
Selective self-assembly at room temperature of individual freestanding Ag2Ga alloy nanoneedles
X-ray-diffraction pattern from needles grown on a thin film of Ag.Inset(SAD) selected area diffraction pattern from a single needle that shows that single needles are highly crystalline.
Micro-Wilhelmy and Related Liquid Property Measurements Using Constant-Diameter Nanoneedle-Tipped Atomic Force Microscope Probes
(a) SEM images of a NeedleProbe with simple cylindrical geometry. (b) Schematic o the AFM experimental setup for liquid probing using NeedleProbe. (c) Top: schematic of the meniscus formation between the NeedleProbe and the liquid surface. Bottom: Typical force vs. distance (F-D) curve of the NeedleProbe on a liquid surface. The red line is extension and the blue line is the retraction force curve.
Free-Standing Biomimetic Polymer Membrane Imaged with Atomic Force Microscopy
