Applications of MAC Mode AFM in Biology, Pharmaceutical, and Other Bio-Related Industries

This paper studies the process of corrosion using scanning probe microscopy (SPM)

Manipulation of gold nanoparticles in liquids using MAC mode Atomic Force Microscopy allows for the free construction of arbitrary shaped nanostructures.

This document introduces the use of AFM probes as chemically selective biosensors with affinity probes. By attaching ligand molecules to the tips of the probes, AFM probes can be transformed into sensitive, chemically selective biosensors.

This application note thoroughly characterizes the oxygen-elimination capability of the standard environmental chamber of the Agilent 5500 AFM. The note provides measurements of liquid imaging and atomic resolution in oxygen-free environment. The well-known transition between Au (1 x 1) atomic lattice and Cu (√3 x √3) under potential deposition (UPD) structure on Au (111) surface at different electrochemical potentials is demonstrated with the in situ high-resolution capability.

This document introduces the capability of Atomic Force Microscopy (AFM) in studying the temperature and humidity control application of Polyvinyl Alcohol (PVA) surfaces. AFM can image insulating materials with atomic resolution and measure various properties of polymers and surface structures, including friction, adhesion, and viscoelasticity. AFM measurements can be performed at the molecular level. The document also discusses the influence of the environment and the history of a polymer on its morphology and material properties, as well as the effects of annealing and exceeding the glass transition temperature on polymer chains. Taking polyvinyl alcohol as an example, exceeding its glass transition temperature can give the polymer chains the mobility to migrate into more energetically favorable orientations.
