High viscosity environments: an unexpected route to obtain true atomic resolution with atomic force microscopy.
Atomic force microscopy (AFM) is widely used in liquid environments, where true atomic resolution at the solid-liquid interface can now be routinely achieved. It is generally expected that AFM operation in more viscous environments results in an increased noise contribution from the thermal motion of the cantilever, thereby reducing the signal-to-noise ratio (SNR). Thus, viscous fluids such as ...
متن کاملForce-feedback High-speed Atomic Force Microscope
High-speed atomic force microscopy (HSAFM) has enabled researchers to view the nanometer-scale dynamic behavior of individual biological and bio-relevant molecules at a molecular-level resolution under physiologically relevant time scales, which is the realization of a dream in life sciences. These high-speed imaging applications now extend to the cellular/bacterial systems with the use of a sm...
متن کاملElectrostatic force microscope for probing surface charges in aqueous solutions.
A scanning force microscope was converted to an electrostatic force microscope by charging the usually neutral cantilever with phospholipids. The electrostatic force microscope was used to study surface electrostatic charges of samples in aqueous solutions. Lysozymes, DEAE-Sephadex beads, 3-propyltriethoxysilane-treated glass and mica were imaged in water or phosphate buffer with electrostatic ...
متن کاملHigh-resolution scanning SQUID microscope
We have combined a novel low temperature positioning mechanism with a single-chip miniature superconducting quantum interference device ~SQUID! magnetometer to form an extremely sensitive new magnetic microscope, with a demonstrated spatial resolution of ;10 mm. The design and operation of this scanning SQUID microscope will be described. The absolute calibration of this instrument with an idea...
متن کاملAtomic force microscope based biomolecular force-clamp measurements using a micromachined electrostatic actuator.
The authors describe a method for biomolecular force clamp measurements using atomic force microscope (AFM) cantilevers and micromachined membrane-based electrostatic actuators. The actuators comprise of Parylene membranes with embedded side actuation electrodes and are fabricated on a silicon substrate. The devices have a displacement range of 1.8 μm with 200 V actuation voltage, and displacem...
