SPM-Nanoa - Applications
Scanning Probe Microscope/Atomic Force Microscope
Application software for a wide variety of samples, from soft to hard materials, can provide powerful help for observing what you want to observe.
What do you want to observe?
Observation of silica nanoparticles confirmed uniformity of nanoparticle sizes.
The large particles shown in the center are extracellular vesicles. With the ability to not only observe shapes, but also evaluate mechanical properties, the system is expected to be useful for identification and Drug Delivery System (DDS) research for exosomes, liposomes, and typical polymer micellization pathogens, and other applications (using Nano 3D Mapping Fast).
PVP/CNF Composite Materials
A water mixture of cellulose nanofiber (CNF) and polyvinylpyrrolidone (PVP) was observed electrospun onto a silicon substrate. The surface shape image shows the cylindrical shape of the fibers and the phase image shows physical property differences of CNF and PVP fibers as differences in contrast.

A patch-shaped lipid membrane about 6 nm thick was observed (arrow) near the center of the surface shape image (left). The force curve acquired from on top of the lipid membrane (right) indicates the variations in force generated as the probe penetrated the membrane.
Single BaTiO3 Crystal
BaTiO3, a strong dielectric, was observed using the piezoelectric force mode (PFM).
The amplitude and phase images clearly show the polarized domain structure.
