Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Area of Science:

  • Colloid and Surface Science
  • Materials Science
  • Physical Chemistry

Background:

  • Colloidal particle stability is governed by interfacial forces, primarily van der Waals and electrostatic forces described by Derjaguin, Landau, Verwey, and Overbeek (DLVO) theory.
  • Emerging research suggests short-ranged forces, or structure forces, play a crucial role in colloidal systems, necessitating advanced measurement techniques.
  • Understanding these forces is critical for controlling interfacial phenomena in various applications, from nanotechnology to material formulation.

Purpose of the Study:

  • To investigate interfacial forces between silica particles and silica wafer surfaces using atomic force microscopy (AFM) colloid probe technique.
  • To analyze measured forces against predictions from the classical Derjaguin, Landau, Verwey, and Overbeek (DLVO) theory, considering 'constant charge' and 'constant potential' models.
  • To identify and characterize short-range forces influencing colloidal interactions, particularly in low ionic strength environments.

Main Methods:

  • Utilized atomic force microscopy (AFM) with a colloid probe to measure the resultant force as a function of separation distance between silica surfaces.
  • Conducted measurements in solutions with varying ionic concentrations, including high-purity Milli-Q water.
  • Analyzed experimental force-distance curves by comparing them with theoretical predictions derived from DLVO theory models.

Main Results:

  • AFM measurements revealed discrepancies between predicted forces from DLVO theory and experimentally observed forces between hydrophilic silica surfaces.
  • A strong, short-range structure force was identified between the silica particle and silica wafer surfaces.
  • This structure force was observed even at extremely low ionic concentrations, such as in Milli-Q water.

Conclusions:

  • The classical DLVO theory, while foundational, does not fully capture the interfacial forces governing interactions between hydrophilic silica surfaces.
  • Short-range structure forces exert a significant influence on colloidal particle stability and interfacial phenomena, especially in dilute solutions.
  • These findings underscore the importance of considering structure forces for accurate modeling and prediction of colloidal system behavior.
