Probing starch-iodine interaction by atomic force microscopy.

Light Emission from CdS Quantum Dots Stabilized by Sugars

CdS nanoparticles were successfully synthesized using starch, amylopectin and maltodextrin, as a capping agent. Optical properties of the final products have been investigated by photoluminescence spectroscopy and Raman scattering. The atomic force microscopy gave a particle of an average size of approximately 6 nm. Our research reveals that all prepared sugar–quantum dot aqueous solutions were...

Probing attractive forces at the nanoscale using higher-harmonic dynamic force microscopy

Probing Specific Interaction Forces Between Human IgG and Rat Anti-Human IgG by Self-Assembled Monolayer and Atomic Force Microscopy

Interaction forces between biological molecules such as antigen and antibody play important roles in many biological processes, but probing these forces remains technically challenging. Here, we investigated the specific interaction and unbinding forces between human IgG and rat anti-human IgG using self assembled monolayer (SAM) method for sample preparation and atomic force microscopy (AFM) f...

Probing the morphology and tribo-response of nanostructured fluid films for personal care applications

A methodology is presented for probing silicone-based polymer-surfactant complex films a few nanometers in thickness with atomic force microscopy (AFM). The films include 2D regions of liquid character interspersed in regions of solid character. Images in dynamic regimes of net repulsive compared to net attractive interaction show remarkable differences, and are compared with contact mode image...

Ultrastructural analysis of buckwheat starch components using atomic force microscopy.

UNLABELLED Morphological and structural features of buckwheat starch granules and nanocrystals were examined using atomic force microscopy and dynamic light scattering. Partially digested starch granules revealed a clear pattern of growth rings with the central core revealing lamellar structure. Atomic force microscopy and dynamic light scattering experiments revealed that the buckwheat starch ...
