The work investigates the adhesive/cohesive molecular and physical interactions together with nanoscopic features of commonly used orally disintegrating tablet (ODT) excipients microcrystalline cellulose (MCC) and D-mannitol. This helps to elucidate the underlying physico-chemical and mechanical mechanisms responsible for powder densification and optimum product functionality. Atomic force micr...
Visualisation of nano-scale biomolecules aids understanding and development in molecular biology and nanotechnology. Detailed structure of nucleosomes adsorbed to mica has been captured in the absence of chemical-anchoring techniques, demonstrating the usefulness of non-contact atomic force microscopy (NC-AFM) for ultra-high resolution biomolecular imaging. NC-AFM offers significant advantages ...
Knowledge of surface forces is the key to understanding a large number of processes in fields ranging from physics to material science and biology. The most common method to study surfaces is dynamic atomic force microscopy (AFM). Dynamic AFM has been enormously successful in imaging surface topography, even to atomic resolution, but the force between the AFM tip and the surface remains unknown...
Polydimethylsiloxane (PDMS) surface consisting irregular pattern was investigated to develop cell-based biochip using PDMS. PDMS surface was modified with nano- and micro-combined patterns using surface deformation technology. Hydrophobicity of nano-patterned PDMS surface was sustained. Nevertheless it has irregular patterns consisting of micro- and nano-patterns. According to atomic force micr...
We demonstrated embossed and intaglio nanopatterning using Nanopipette based on the QTF-AFM (Quartz Tunning Fork-Atomic Force Microscopy) system. Used materials in the patterning system were nanoparticles solution and acetone for delivery solution mica and flat plastic for substrate mica. By realizing the nano-scaled liquid ejection technique with the pulled nanopipette conbined QTF-AFM, variou...
Most biologists think that AFM has only a limited use in biological research due to its inability to study other than surface structures. Therefore, a BIO-AFM system has been developed to combine both AFM imaging and fluorescence detection, which acts as a powerful tool for a better understanding of dynamic cell processes. In this study, based on a custom-made BIO-AFM system, the elasticity and...
