Probing physical properties at the nanoscale using atomic force microscopy

Techniques that measure physical properties at the nanoscale with high sensitivity are significantly limited considering the number of new nanomaterials being developed. The development of atomic force microscopy (AFM) has lead to significant advancements in the ability to characterize physical properties of materials in all areas of science: chemistry, physics, engineering, and biology have ma...

Chemical Force Microscopy Nanoscale Probing of Fundamental Chemical Interactions

Intermolecular forces impact a wide spectrum of problems in condensed phases: from molecular recognition, self-assembly, and protein folding at the molecular and nanometer scale, to interfacial fracture, friction, and lubrication at a macroscopic length scale. Understanding these phenomena, regardless of the length scale, requires fundamental knowledge of the magnitude and range of underlying w...

Characterization of Fish Gelatin at Nanoscale Using Atomic Force Microscopy

Atomic force microscopy (AFM) was used as a meaningful tool to characterize the nanostructure of gelatin from catfish (Ictalurus punctatus) skin. The gelatins extracted with pretreatments including acid pretreatment, alkaline pretreatment, and alkaline followed by acid pretreatment (optimized extraction conditions). The resulting gelatins were imaged using AFM and their nanostructure was studie...
