Application of Atomic Force Microscopy in Food Sciences and Detection of Food Toxin

Abstract

In recent years, atomic force microscopy (AFM) has shown to be a versatile tool for determining surface morphology, interaction forces and roughness measurement. The AFM technique is a 3D topographical modality with a high atomic resolution, especially in the vertical orientation. AFM is a type of scanning probe microscope that uses a near-field technique that involves a sharp tip interacting with the atoms on the sample surface. This adaptable method can be used to get high resolution sample images and examine local interactions in air or liquid environments. Qualitative macromolecule, quantitative structure analysis and polymer imaging, molecular interaction, surface topography, and Nano food characterization are all examples of AFM applications in food science and technology research. The current challenge in applying AFM to food research is a lack of adequate methods for various food systems. A better grasp of AFM technology and the development of related methodology for complex food systems would lead to a deeper understanding of food qualities at the macromolecular level and expand their applicability.
